The synthesis of a small heat shock/alpha-crystallin protein in Artemia and its relationship to stress tolerance during development. (1/390)

Fertilized oocytes of the brine shrimp Artemia franciscana undergo either ovoviviparous or oviparous development, yielding free-swimming larvae (nauplii) or encysted gastrulae (cysts), respectively. Encystment is followed by diapause, wherein metabolism is greatly reduced; the resulting cysts are very resistant to extreme stress, including desiccation and long-term anoxia. The synthesis of p26, a small heat shock/alpha-crystallin protein produced only in oviparously developing Artemia, is shown in this paper to be transcriptionally regulated. A p26 mRNA of about 0.7 kb was detected on Northern blots in the second day after oocyte fertilization. It peaked as embryos encysted and declined rapidly when activated cysts resumed development. The appearance of p26 protein, as indicated by immunoprobing of Western blots, followed mRNA by 1 day; it also increased as encystment occurred but remained constant during postgastrula development of cysts. However, p26 underwent a marked reduction during emergence of nauplii and could not be detected in cell-free extracts of second-instar larvae. p26 entered nuclei of encysting embryos soon after synthesis and was localized therein as late as instar II, when it was restricted to a small set of salt gland nuclei. First-instar larvae derived from cysts were more thermotolerant than larvae that had developed ovoviviparously, but synthesis of p26 was not induced by heat under the experimental conditions employed. Additionally, transformed bacteria synthesizing p26 were more thermotolerant than bacteria that lacked the protein. The results support the proposal that p26, a developmentally regulated protein synthesized during embryo encystment, has chaperone activity in vivo and protects the proteins of encysted Artemia from stress-induced denaturation.  (+info)

Microbial control of the culture of Artemia juveniles through preemptive colonization by selected bacterial strains. (2/390)

The use of juvenile Artemia as feed in aquaculture and in the pet shop industry has been getting more attention during the last decade. In this study, the use of selected bacterial strains to improve the nutritional value of dry food for Artemia juveniles and to obtain control of the associated microbial community was examined. Nine bacterial strains were selected based on their positive effects on survival and/or growth of Artemia juveniles under monoxenic culture conditions, while other strains caused no significant effect, significantly lower rates of survival and/or growth, or even total mortality of the Artemia. The nine selected strains were used to preemptively colonize the culture water of Artemia juveniles. Xenic culture of Artemia under suboptimal conditions yielded better survival and/or growth rates when they were grown in the preemptively colonized culture medium than when grown in autoclaved seawater. The preemptive colonization of the culture water had a drastic influence on the microbial communities that developed in the culture water or that were associated with the Artemia, as determined with Biolog GN community-level physiological profiles. Chemotaxonomical characterization based on fatty acid methyl ester analysis of bacterial isolates recovered from the culture tanks was performed, and a comparison with the initially introduced strains was made. Finally, several modes of action for the beneficial effect of the bacterial strains are proposed.  (+info)

Natural copepods are superior to enriched artemia nauplii as feed for halibut larvae (Hippoglossus hippoglossus) in terms of survival, pigmentation and retinal morphology: relation to dietary essential fatty acids. (3/390)

Replicate groups of halibut larvae were fed to d 71 post-first feeding (PFF) either the marine copepod, Eurytemora velox, or Artemia nauplii doubly enriched with the marine chromist or golden algae, Schizochytrium sp., (Algamac 2000) and a commercial oil emulsion (SuperSelco). The fatty acid compositions of eyes, brains and livers from larvae fed the two diets were measured, and indices of growth, eye migration and skin pigmentation were recorded along with histological examinations of eye and liver. The docosahexaenoic acid [22:6(n-3); DHA]/eicosapentaenoic acid [20:5(n-3); EPA] ratios in Artemia nauplii enriched with the SuperSelco and Algamac 2000 were 0.4 and 1.0, respectively. The E. velox copepods were divided into two size ranges (125-250 and 250-400 microm) with the smaller size range containing the highest level of (n-3) highly unsaturated fatty acids (HUFA). The DHA/EPA ratios for the two size ranges of copepods were 2.0 and 0.9, respectively. The total lipids of eyes, brains and livers of larvae fed copepods had higher levels of DHA and lower levels of EPA than those of larvae fed enriched Artemia. The percentage of survival of the halibut larvae was significantly higher when copepods rather than enriched Artemia nauplii were fed, but larval specific growth rates did not differ. The indices of eye migration were high and not significantly different in larvae fed the two diets, but the percentage of larvae undergoing successful metamorphosis (complete eye migration and dorsal pigmentation) was higher in larvae fed copepods (40%) than in larvae fed enriched Artemia (4%). The rod/cone ratios in histological sections of the retina were 2.5 +/- 0.7 in larvae fed copepods and 1.3 +/- 0.6 in larvae fed enriched Artemia (P < 0.01). Histological examination of the livers and intestines of the larvae were consistent with better assimilation of lipid from copepods than lipid from Artemia nauplii up to 46 d post-first feeding. Thus, marine copepods are superior to enriched Artemia as food for halibut larvae in terms of survival, eye development and pigmentation, and this superiority can be related to the level of DHA in the feed.  (+info)

Distinct functions of eukaryotic translation initiation factors eIF1A and eIF3 in the formation of the 40 S ribosomal preinitiation complex. (4/390)

We have used an in vitro translation initiation assay to investigate the requirements for the efficient transfer of Met-tRNAf (as Met-tRNAf.eIF2.GTP ternary complex) to 40 S ribosomal subunits in the absence of mRNA (or an AUG codon) to form the 40 S preinitiation complex. We observed that the 17-kDa initiation factor eIF1A is necessary and sufficient to mediate nearly quantitative transfer of Met-tRNAf to isolated 40 S ribosomal subunits. However, the addition of 60 S ribosomal subunits to the 40 S preinitiation complex formed under these conditions disrupted the 40 S complex resulting in dissociation of Met-tRNAf from the 40 S subunit. When the eIF1A-dependent preinitiation reaction was carried out with 40 S ribosomal subunits that had been preincubated with eIF3, the 40 S preinitiation complex formed included bound eIF3 (40 S.eIF3. Met-tRNAf.eIF2.GTP). In contrast to the complex lacking eIF3, this complex was not disrupted by the addition of 60 S ribosomal subunits. These results suggest that in vivo, both eIF1A and eIF3 are required to form a stable 40 S preinitiation complex, eIF1A catalyzing the transfer of Met-tRNAf.eIF2.GTP to 40 S subunits, and eIF3 stabilizing the resulting complex and preventing its disruption by 60 S ribosomal subunits.  (+info)

Isolation and characterization of the gene coding for Artemia franciscana TATA-binding protein: expression in cryptobiotic and developing embryos. (5/390)

Genomic and cDNA clones coding for the Artemia franciscana homolog of the TATA box-binding protein (TBP) were isolated. The C-terminal region of the predicted protein displays up to 92% sequence identity with the conserved C-terminal regions of TBPs from other species. The gene is divided in seven exons that expand over a region of 33 kb. The position of the four introns located in the conserved C-terminal region has been compared with those of other species. Two of these introns have been generally conserved during evolution, another is an arthropod specific intron, present in Drosophila melanogaster and A. franciscana, and the other is only conserved between vertebrates and A. franciscana. Primer extension experiments detected several transcription initiation sites. Northern blot analyses showed the presence of four mRNAs of estimated sizes of 6.8, 2.6, 1.6 and 1.1 kb. Except for the low expression of the 6.8 and 2. 6 kb RNAs in encysted embryos, steady-state levels showed little variation during the activation of the encysted embryo and the first steps of embryonic and larval development. The amount of TBP protein expressed in encysted embryos and developing larvae has been analyzed by Western blot. Cryptobiotic embryos contain significant amounts of TBP although the level of expression increased almost twice during the first 20 h of development. The presence of TBP protein in cryptobiotic embryos suggests that TBP does not play, by itself, a critical role in the arrest of transcription characteristic of these resistance forms.  (+info)

APH-1, a POU homeobox gene expressed in the salt gland of the crustacean Artemia franciscana. (6/390)

We characterized the first POU-homeoprotein in a crustacean (designated APH-1 for Artemia POU-Homeoprotein, EMBL Y15070). The amino acid sequence of the APH-1 POU-domain is identical, except for two residues, to that of the two class III POU proteins Cf1-a (Drosophila) and POU-M1 (Bombyx mori). Southern blot analysis suggests that crustaceans have only one class III POU gene. RT-PCR and whole-mount in situ hybridization show that APH-1 mRNA is present in larvae specifically in the salt gland, an organ which is involved in osmoregulation, and disappears in the adult.  (+info)

NF-Y associates with H3-H4 tetramers and octamers by multiple mechanisms. (7/390)

NF-Y is a CCAAT-binding trimer with two histonic subunits, NF-YB and NF-YC, resembling H2A-H2B. We previously showed that the short conserved domains of NF-Y efficiently bind to the major histocompatibility complex class II Ea Y box in DNA nucleosomized with purified chicken histones. Using wild-type NF-Y and recombinant histones, we find that NF-Y associates with H3-H4 early during nucleosome assembly, under conditions in which binding to naked DNA is not observed. In such assays, the NF-YB-NF-YC dimer forms complexes with H3-H4, for whose formation the CCAAT box is not required. We investigated whether they represent octamer-like structures, using DNase I, micrococcal nuclease, and exonuclease III, and found a highly positioned nucleosome on Ea, whose boundaries were mapped; addition of NF-YB-NF-YC does not lead to the formation of octameric structures, but changes in the digestion patterns are observed. NF-YA can bind to such preformed DNA complexes in a CCAAT-dependent way. In the absence of DNA, NF-YB-NF-YC subunits bind to H3-H4, but not to H2A-H2B, through the NF-YB histone fold. These results indicate that (i) the NF-Y histone fold dimer can efficiently associate DNA during nucleosome formation; (ii) it has an intrinsic affinity for H3-H4 but does not form octamers; and (iii) the interactions between NF-YA, NF-YB-NF-YC, and H3-H4 or nucleosomes are not mutually exclusive. Thus, NF-Y can intervene at different steps during nucleosome formation, and this scenario might be paradigmatic for other histone fold proteins involved in gene regulation.  (+info)

Use of ribonuclease VI from Artemia for the determination of cytidine 2'-phosphate. (8/390)

An enzymatic method has been developed for the quantitative measurement of cytidine 2'-phosphate. Concentrations in the micromolar range can be measured even in the presence of at least five times greater concentrations of a variety of related nucleotides. The method is also suitable for detection of the 2',3'-cyclic nucleotide 3'-phosphodiesterase (EC 3.1.4.37) and its discrimination from the 2',3'-cyclic nucleotide 2'-phosphodiesterase (EC 3.1.4.16).  (+info)

Since Darwins time, waterbirds have been considered an important vector for the dispersal of continental aquatic invertebrates. Bird movements have facilitated the worldwide invasion of the American brine shrimp Artemia franciscana, transporting cysts (diapausing eggs), and favouring rapid range expansions from introduction sites. Here we address the impact of bird migratory flyways on the population genetic structure and phylogeography of A. franciscana in its native range in the Americas. We examined the sequence variation for two mitochondrial gene fragments (COI and 16S for a subset of the data) in a large set of population samples representing the entire native range of A. franciscana. Furthermore, we performed Mantel tests and redundancy analyses (RDA) to test the role of flyways, geography and human introductions on the phylogeography and population genetic structure at a continental scale. A. franciscanamitochondrial DNA was very diverse, with two main clades, largely corresponding to Pacific

Hydrated encysted embryos of the brine shrimp Artemia franciscana have the ability to withstand years in anaerobic sea water using metabolic strategies that enable them to inactivate all cell metabolic activities and then to resume development when placed in aerobic sea water. However, this unique characteristic of Artemia franciscana embryos is lost during a very short period, at the embryonic­larval transition period of development, coincident with the appearance of prenauplius larvae. Thus, while encysted embryos show complete inhibition of proteolysis over at least 4 years under anoxia, control of this activity, together with resistance to anoxia, is lost in newly hatched nauplius larvae after only a few days in anaerobic sea water. In contrast to encysted embryos, young larvae in anaerobic sea water produce large amounts of lactic acid, which reaches a concentration of nearly 50 mmol l-1 within 12 h of incubation. The accumulated lactic acid is believed to reduce the intracellular pH ...

Late Embryogenesis Abundant (LEA) proteins are highly hydrophilic, low complexity proteins that were originally discovered in plants. The expression of LEA proteins has been tightly correlated with desiccation tolerance in anhydrobiotic organisms. We have currently identified and sequenced six LEA genes in embryos of the brine shrimp Artemia franciscana. Two of the six Afrlea genes (Afrlea2 and Afrlea3m) have been cloned into a bacterial expression system, over-expressed, and purified. Based on deduced amino acid sequences, AfrLEA3m is predicted by subcellular targeting programs to be mitochondrial localized (now confirmed experimentally), while AfrLEA2 is predicted to be cytosolic. Multiple splice variants for both AfrLEA2 and AfrEA3m have been detected in A. franciscana using antibodies produced against recombinant AfrLEA2 and AfrLEA3m. Two splice variants are observed for AfrLEA2 with estimated molecular weights of 75 and 45 kDa, and four splice variants are observed for AfrLEA3m with ...
Heat shock proteins (HSPs) are highly conserved and present in organisms under normal physiological conditions and function in protein folding, degradation and localization. HSPs are also synthesized in response to environmental stressors such as heat, anoxia, desiccation and cold. These molecular chaperones protect other proteins from irreversible denaturation during stress, thereby maintaining proteostasis and allowing cells to survive unfavorable conditions. Artemia franciscana, commonly known as brine shrimp, are micro-crustaceans that live in harsh aquatic environments and experience high salinity, extreme temperatures, variable water levels, and hypoxia. In anticipation of stressful conditions, A. franciscana alter their life cycle by releasing cysts that enter diapause. Nauplii (larvae) emerge after diapause termination or when favorable conditions return. The effect of cold shock on three HSPs, HSP90, HSP70 and HSP40 was studied in the nauplii of A. franciscana during 6 h of cold-shock ...
The physicochemical factors of the trial pond (table 1), was determined according to the recommended procedure to measure the environmental factors [7].. Importance of Artemia as the live food source has been recognized as of 1930s in aquaculture. For the time being, shrimp, various decorative and sea and caviar fish husbandry industry depend on Artemia [1,8], so that annually, more than 10000 tons of the same is produced and consumed in various countries all over the world. Whereas harvesting the Artemia cysts from global natural water sources such as Great Salt Lake, Urmia Lake and other relevant natural habitats indicate a significant decline due to a variety of reasons, therefore during recent year Artemia culture in pound, ponds and salty lakes and water drainages of the countries, especially those with arid and semi-arid climates is of high importance. Through culturing the Artemia species, while optimized utilizing the salty water sources of such countries, the same will be resulted in ...

The limited availability of alternative foods to replace natural prey hinders cost-effective mass production of ladybird beetles for augmentative biological control. We compared the effects of powdered vs. whole Artemia franciscana (A. franciscana) (brine shrimp) eggs with or without a dietary supplement on development and reproduction of Coleomegilla maculata (C. maculata) (Coleoptera: Coccinellidae). We tested the hypotheses that (1) powdered A. franciscana eggs are more suitable than whole eggs; and (2) palmitic acid, a common fatty acid in natural prey, i.e., aphids, is an effective dietary supplement. Development time, pre-imaginal survival, sex ratio, and body weight of adults did not differ significantly amongst individuals fed powdered vs. whole eggs, with or without 5% palmitic acid. Significantly more oviposition occurred when females were fed powdered eggs than whole eggs and powdered eggs with 5% palmitic acid than whole eggs with or without 5% palmitic acid.

ABSTRACT: Development of Artemia culture is needed to support larvae production sustainability for fisheries commodities such as fish and shrimps. One of concern facing Artemia production is newly infectious and non-infectious diseases that cause lowering quality of the Artemia growth and survival. Disease control on Artemia production was depend on the different sensitivity of the cyste uses and divers patogenity that potentially infect the Artemia. Amongs them, bacterium, called Vibrio spp is the most prominent infectious agents. As an invertebrate, Artemia has no equipped with an adaptive immune system, thus, they depends on the natural immune system without memory system. One of natural immune system owned by Artemia is activation of prophenoloxidase (proPO) and phenoloxidase (PO) enzymes that play key role on melanization, cell-adhesion, degranulation and encapsulation processes. This review article focus on the effectiveness of natural immune system activated by β-glukan and their immune ...

The authors suggest that the nematocysts and spirocysts have complementary roles, but that their level of interactivity depends on the nature of the prey. Thus, nematocysts predominate with soft-bodied prey that they can penetrate, while spirocysts predominate when the target surface is hard enough for the spirocysts to adhere, but too hard for the nematocysts to penetrate. The authors also speculate that the spirocysts may assist in prey capture by tangling and interfering with the swimming appendages of the prey. How much force is exerted by a small swimming crustacean like the nauplius of a brine shrimp Artemia salina, and how many nematocysts and/or spirocysts would it take to secure a single, struggling individual? Based on motion analysis of swimming Artemia nauplii (each 0.01mg live mass), the researchers estimate that a force of 0.2 µN is exerted per power stroke. Since a single microbasic-p-mastigophore (penetrant) nematocyst can withstand forces of 1.5-4.4 µN (authors estimates for ...
In the present study, the effect of salinity (50, 100, 150, 200 and 250 ppt) was studied on competition between the sexual Artemia urmiana and parthenogenetic Artemia population of lake Urmia neighbouring lagoons. After cysts hathing, nauplii of both Artemia were reared separately in 1.5 L cylindrical containers containing different salinity. After puberty, the competition experiments between the Artemia populations were set up. Three pairs of sexual Artemia (3 adult male and 3 adult female) and three adult asexual female Artemia were randomly collected from each salinity and transferred to 1.5 L cylindrical containers (in 4 replicates) containing water with similar salinities. Whole population were counted once a week and the population composition were determined in all experimental treatments and compared with the control group. The experiments continued until one population overcome the other population or both population reach to equilibrium. At the end of the culture period in order to ...
The present study aimed to optimize the enrichment protocols of Artemia nauplii with highly unsaturated fatty acid liposomes. Three different types of liposomes formulated with krill phospholipid extract were tested, using a commercial emulsion as the control treatment. The incubation time of the nauplii in the enrichment medium was chosen as the first variable studied. Total lipid, lipid class and fatty acid profiles were analyzed in enriched nauplii after 18 and 21 h incubation in the enrichment media. A third sampling point at 24 h, where nauplii had been kept in clean seawater at 28 °C for 3 h, was established to emulate potential changes in the nutritional value of the nauplii after some hours in the larval rearing tank. A second objective of the study was the establishment of a suitable liposome-based diet for the rearing of gilthead sea bream larvae, as a model of marine fish..

The metabolic status of encysted Artemia embryos under anoxic conditions has been studied by calorimetry. Previous work demonstrated a very low, but still measurable, source of metabolic heat (31 nW mg-1 dry mass) after 6 days of anoxia, attributed to the catabolism of small amounts of carbohydrate storage compounds and the unusual nucleotide diguanosine tetraphosphate. Our results indicate that the heat measured drops below the detection limits of our calorimeter (11 nW mg-1 dry mass) after 1.5 h of anoxia, in sharp contrast with previously published results. The possible sources of error that could explain this difference, and a re-evaluation of the metabolic status of cysts during anoxia, are discussed. We conclude that if the cysts are carefully protected from oxygen they become essentially ametabolic. ...

Artemia cysts is known as the shrimp of brine and regarded as a kind of important biological bait by the extens - Manufacturer - Producer - PSL47986YH
Use brine to hatch the artemia. Wilkerson (1998) recommends the use of inexpensive granular salts with low salinity. Mix 2 teaspoons of granulated salt tea with 2 liters of tap water (chlorinated). When the salt dissolves, aerate about 1 hour and add nearly ¼ teaspoon of artemia eggs. Adequate aeration will result in high hatching rates and healthy larvae. Airstone should not be used, but rigid plastic tubes should be attached to the bottom of the incubator. Do not be afraid of strong aeration. Air bubbles can cause strong water disturbance. Once the eggs have hatched, they can be carried by air bubbles to the surface of the water and fly out, so reduce the amount of aeration. Make sure your aeration tank is illuminated on the first day and for the next 16-20 hours you can see the artemia larvae appear. The newly hatched larvae are very nutritious and can bring about fry immediately. The abdominal sac makes the larvae yellow. By the way, if you have clownfish you have to raise them with newly ...
Artemia is a genus of aquatic crustaceans also known as brine shrimp. Artemia, the only genus in the family Artemiidae, has changed little externally since the Triassic period. The first historical record of the existence of Artemia dates back to the first half of the 10th century AD from Urmia Lake, Iran, with an example called by an Iranian geographer an "aquatic dog", although the first unambiguous record is the report and drawings made by Schlösser in 1757 of animals from Lymington, England. Artemia populations are found worldwide in inland saltwater lakes, but not in oceans. Artemia are able to avoid cohabiting with most types of predators, such as fish, by their ability to live in waters of very high salinity (up to 25%). The ability of the Artemia to produce dormant eggs, known as cysts, has led to extensive use of Artemia in aquaculture. The cysts may be stored for long periods and hatched on demand to provide a convenient form of live feed for larval fish and crustaceans. Nauplii of ...

Encysted embryos of Artemia franciscana undergo a dramatic respiratory depression upon release from the adult female as they enter a state of hypometabolism termed diapause. The mechanisms by which such a respiratory depression is achieved remain unexplained. Evidence presented here shows that strategic enzymes involved in trehalose catabolism are inhibited during diapause, namely trehalase, hexokinase, pyruvate kinase and pyruvate dehydrogenase. Trehalose is the sole source of fuel in the embryos of A. franciscana, and hence downregulation of trehalose catabolism results in severe limitation of metabolic fuel available to the embryo during diapause. Western blot data demonstrates that pyruvate dehydrogenase becomes phosphorylated during entrance into diapause, and as a consequence, one would predict PDH to be strongly inhibited in this state. Restriction of glycolytic flux will lead to metabolic starvation of the mitochondrion, and in turn will reduce mitochondrial oxidative phosphorylation during

How do desert plants survive baking heat and constant drought? With the help of cryptobiotic friends!. Cryptobiotic? It sounds like something out of a graveyard horror movie. Actually, the word means "hidden life" (from the Greek words kruptos and biotikos). Invisible to the casual observer, dense mats of cryptobiotic organisms, including cyanobacteria, lichens, mosses, green algae, and microfungi, mix with sand and clay to form a life-sustaining soil in desert regions. Without it, a lot of desert plants wouldnt survive.. Imagine yourself as a desert plant exposed to constant heat that threatens to bake you dry and wind that blows sand out from under your roots. You would have a hard time making it. Desert heat and sand are not hospitable to vegetation that needs stable, moist soil for root growth. But weave together a combination of tiny organisms, sand, and clay, and you get a mat of living soil that resists erosion and holds on to water like a sponge-enough to make a difference to a lot of ...
The estimation of LC50 for plant extract is a valuable criterion to demonstrate the presence of toxic constituents. The results obtained for LC50 of MBM on brine shrimp lethality assay exerted that the extract possesses bioactive compounds with very week cytotoxic effects. Previously significant correlation has been reported between the LC50 of brine shrimp lethality and the LD50 for oral acute toxicity in mice [31]. Accordingly LC50 , 10 μg/ml possesses LD50 between 100 and 1000 mg/kg; LC 50 , 20 μg/ml possesses LD50 between 1000 and 2500 mg/kg, and LC50 , 25 μg/ml possesses LD 50 between 2500 and 8000 mg/kg. The LC50 obtained at 24 h of the treatment of MBM for brine shrimps demonstrated that LD50 for oral acute toxicity study should be higher from 4000 mg/kg treatment.. Free radicals are classified as extremely reactive species and are considered to be implicated in varied human diseases including the chronic and acute renal disorders. These are recognized as the main factors involved in ...

Brine Shrimp are a very common food for fresh and saltwater fish, but do not hold much when it comes to nutritional value, but when gut-loaded they can provide the same nutritional value of the food that is contained within the gut of the brine shrimp. Brine shrimp are commonly used to entice new, or finicky fish into

Argyrotaenia franciscana is bivoltine or multivoltine, depending on location. In warmer inland areas of California, larvae aestivate during the summer and only two generations are completed. In cooler coastal areas there may be up to 5 continuous overlapping generations with adults present year-round.. Eggs are laid on smooth surfaces of leaves, fruits, and twigs in masses that contain approximately 200 individual eggs. Early instar larvae skeletonize leaves under a silk shelter; later instars roll, fold, or web leaves together or to fruits. Larvae complete 5-7 instars in a period of 20-30 days. Larvae or pupae overwinter in dead leaves, in mummified fruits, under buds, or on weedy herbaceous plants in the same vicinity as the host. Pupation occurs in the final larval shelter.. Larvae can cause economic damage by directly feeding on developing fruit in citrus, apple, and grape. Larvae may also feed on stems, causing fruit to drop.. Host plants. Argyrotaenia franciscana has been described as one ...

Res., 71(4): 257-265 .. Early life stages from a marine fish species, Fundulus heteroclitus, were exposed to sublethal doses of 3,3,4,4,5 pentachlorobiphenyl (PCB126) to evaluate its effects on ecologically relevant responses: growth and behavior. A few hours after fertilisation, eggs were treated topically with PCB126 (2.5-50 pg egg-1). Four days post-hatching (dph), morphological changes (body length and malformations), spontaneous locomotor activity (active swimming speed, rate of travel, % inactivity), prey capture ability (Artemia franciscana nauplii) and whole body EROD activity were evaluated in larvae. Untreated larvae collected at 0.5, 1, 2, 3, 4 dph were also examined. PCB126 did not increase the mortality or malformation rates. Body length and spontaneous locomotor activity were altered ...
Figure 2b shows that the ethyl acetate extract from Mabea fistulifera was the most efficient one, while the butanol, dichloromethane and hexane fractions were less efficient or as efficient as the original M. fistulifera crude ethanol extract. Previous work showed that the ethanol extract from the fruits of this plant presented significant lethality to brine shrimp larvae. The isolation of a bioactive naringenin coumaroyl glycoside and two other inactive naringenin derivatives, along with gallic acid ethyl ester was reported (Garcez et al., 1997). The HPLC chromatogram of the ethyl acetate fraction of the ethanol extract of M. fistulifera showed peaks at Rt 2.45 and 3.31 min. (Table 2) which UV spectra are compatible with a benzenoid compound (Silverstein et al., 1991). In fact, gallic acid was isolated from the ethyl acetate fraction by our group, along with minor gallotannins (structure under elucidation).. Concerning Bathysa australis extracts (Figure 2c), we observed that the ethyl acetate, ...

We demonstrate how optical tweezers may provide a sensitive tool to analyze the fluidic vibrations generated by the movement of small aquatic organisms. A single gold nanoparticle held by an optical tweezer is used as a sensor to quantify the rhythmic motion of a Nauplius larva (Artemia salina) in a water sample. This is achieved by monitoring the time dependent displacement of the trapped nanoparticle as a consequence of the Nauplius activity. A Fourier analysis of the nanoparticles position then yields a frequency spectrum that is characteristic to the motion of the observed species. This experiment demonstrates the capability of this method to measure and characterize the activity of small aquatic larvae without the requirement to observe them directly and to gain information about the position of the larvae with respect to the trapped particle. Overall, this approach could give an insight on the vitality of certain species found in an aquatic ecosystem and could expand the range of ...

Great Salt Lake-biotype brine shrimp cysts were added to 440-1 saltwater cultures maintained at 20° ,25° , and 30° C. A micronized corn-byproduct was added each day as food. Planktonic bacteria found during growth of the brine shrimp were enumerated on Plate Count Agar (Difco). From the 25° and 30° brine shrimp cultures, a total of seven prevalent bacterial types (five gram-negative and two gram-positive) were isolated from throughout the 12-day growth cycle. Eight antimicrobial agents were tested against these bacteria, with chloramphenicol the most effective antibacterial agent overall, followed by erythromycin and carbenicillin. The bacterial density of the culture medium upon cyst addition was 106 colony forming units (cfu)/ml. The density increased similarly in all cultures from day 1 to day 3, and continued to increase in both the 25°- and 30°- cultures to between 108 and 109 cfu/ml at the end of day 12, at which time many brine shrimp had reached sexual maturity. However, the bacterial

ABSTRACT: Understanding the potential metabolic lifespan of a cohort of marine invertebrate embryos or larvae requires not just precise measurements of respiration rates, but also requires a large number of individual-level measurements to accurately describe the distribution of metabolic rate potentials within that cohort. To this end, we have developed a simple protocol for converting a 384-well microtiter plate into a 384-chamber, microrespirometer, optode using a plate-reading fluorometer for continuous, real-time data acquisition. We have ground-truthed this high-throughput technique using Artemia sp. nauplii at ~48 h post-hydration. In this paper we present ,1000 separate respiration rate measurements on nauplii, providing a novel look at the distribution of metabolic rates within a cohort of larvae. At this high level of individual sampling, we have applied a Shannon Weaver information entropy statistic to describe the complexity of these rate distributions and to show that the range of ...

You first need to obtain their eggs (which are called cysts). These are available from online web sites or your local pet shop. You then need to prepare a water container of around 2 litres and fill it with clean water. Add 1 tsp of Bicarbonate of soda to ensure the ph of the water is 7.5-8.5 and a KH of around 10d. Heat the water to around 18-28°C (64.4-82.4°F) . The eggs will hatch faster at 25-28°C (77-82.4°F) . Add to the water the salt, about 20g (1.5 tbsp) per litre of water. Stir until the salt is totally dissolved. Place the lamp over the container as the Artemia require a bright light source for the first 4 hours in order to hatch. Add the air-stone and pump so that the air-stone is at the bottom of the container. The water requires strong aeration throughout the process. Add the eggs.

Sea Monkey Day. The history of sea monkeys starts, oddly enough, with ant farms. Milton Levine had popularized the idea of Ant-farm kits in 1956 and, presumably inspired by the success of his idea, Harold von Braunhut invented the aquatic equivalent with brine-shrimp. It was really ingenious looking back on it, and ultimately he had to work with a marine biologist to really bring it all together. With just a small packet of minerals and an aquarium youd suddenly have a place rich with everything your brine-shrimp needed to survive. So why sea monkeys? Because who was going to buy brine-shrimp? It was all a good bit of marketing, though the name didnt come about for nearly 5 years. They were originally called "instant life", referencing their just add water nature. But when the resemblance of their tails to monkeys tails was noted by fans, he changed it to Sea-Monkeys and so its been ever since! The marketing was amazing too! 3.2 million pages of comic book advertising a year, and the ...
One good scientific reason for putting brine shrimp into space is brought out by Spooner and colleagues (1992). Brine shrimp can put their eggs in tough cysts that can almost entirely dry out, and development stops until they get into salt water again. This means that you can put brine shrimp into space, start them growing, and be sure that all of that development did in fact occur in space. With almost any other animal, you will have a mix of growth on the ground and in space ...
Objective: The orange-red spectrum of the skin of electric yellow (Labidochromis caeruleus) is one of the idealistic and necessary schemas sought by aquarists and commercial producers. In this study, the effect of live foods meal on the skin coloration of juvenile electric yellow was examined. Methods: 270 fish with an average living body weight was 0.42 ± 0.11 g, and average total length was 3.3 ± 0.35 cm. Their sex was not taken into consideration. . The fish were fed twice in the morning and afternoon by 3-5 percent of the biomass for 8 weeks. The six different treatments (three replicates/treatment) used in the experiment were used. Skin color was measured in below the dorsal fin of all fish. Measurements were recorded at the end of the feeding trial using a Konica Minolta Chroma Meter CR400. Results: At the end of the trial, the carotenoid supplemented diets significantly increased the values of redness (a*), yellowness (b*), and chroma (C*), and decreased the values of

Similarly, for Artemia populations classified by their geographic origin, male and female individuals again separate the Colombian populations from the North American (SFB) populations. According to the analysis, Salina Cero male population is similar to its neighboring Galerazamba population and is also related to the other Colombian populations, and this is consistent with the previous findings using RAPDs and also likely to be explained by the existence of a geographic barrier (Sierra Nevada de Santa Marta). Apparently, as deduced from the influence of lunar cycles and sampling time study the conglomerates formed by brine shrimp are asynchronous. Finally, it is recommended to conduct Artemia surveys preferably late in the evening or alternatively during early morning since Artemia tends to distribute more uniformly during the evening (dark and cool), when water temperature is lower, particularly in saltworks, where the evaporation basins are shallow ...
A tiny marine crustacean inhabiting non-oceanic saline environments, there are over 13 species of brine shrimp. The best known, Artemia salina is located in the Great Salt Lake of Utah and also in the San Francisco Bay in California. These creatures are of great importance, since they provide food to many fish and birds. They are also of considerable interest to researchers and hobbyists.
Abstract: To investigate the maximum accumulation of highly unsaturated fatty acids (HUFA) in Artemia franciscana nauplii through bioencapsulation process, five different concentrations (0 - 4%) of emulsified Odonus niger liver oil were prepared. The prepared emulsions were used to enrich A. franciscana at different time intervals of 6, 12, 18 and 24 h. After the enrichment period, the fatty acid composition of the nauplii were analysed and estimated individually along with freshly hatched A. franciscana and O. niger liver oil. The HUFA content such as linoleic (18: 2n-6), linolenic (18: 3n-3), arachidonic (20: 4n-3 + n-6), eicosapentaenoic (20: 5-n3) and docosahexaenoic (22: 6n-3) acids were 12.87, 0.21, 2.66, 2.86 and 2.30% dry weight (DW), respectively, in O. niger liver oil, and 8.60, 17.20, 1.80, 2.40 and 0.1% DW, respectively, in freshly hatched A. franciscana. During 6 - 24 h of enrichment period, all the above HUFA increased considerably from 8.76 to 10.84, 17.24 to 23.84, 1.16 to 3.98, ...

ABSTRACT. Mixture of three compounds lupeol acetate (1), alpha amyrin acetate(2) and beta amyrin acetate(3) were isolated from the methanolic extract of the stem bark of Artocarpus lackoocha Roxb.(Family: Moraceae).The crude methanol extract as well as its petroleum ether, carbon tetrachloride; chloroform and aqueous soluble Kupchan fractions were studied for antioxidant, antimicrobial and cytotoxic activities. Among the different fractions tested for antioxidant activity, the aqueous soluble partitionate was the most potent with IC50 value of 3.47μg/ml as compared to tertbutyl-1-hydroxytoluene (IC50=27.54μg/ml). Antimicrobial screening of the different extractives was conducted by the disc diffusion method and the crude methanol extract as well as aqueous soluble fractions exhibited moderate antimicrobial activity with zone of inhibition ranging from 7-12 mm. In brine shrimp lethality bioassay, the aqueous soluble materials demonstrated the highest toxicity with LC50 of 1.6μg/ml. β-amyrin ...
Salaria fluviatilis is one of the few freshwater members of the family Blenniidae and occurs around the Mediterranean Basin. This species is vulnerable or endangered in most countries where it occurs. Thus, information on its developmental biology and the establishment of methods for ex situ reproduction of highly endangered populations, to preserve them until natural habitats are restored, are much needed. A technique for the culture of this endangered species in controlled conditions is presented, together with the description of the full developmental sequence, from egg to adult. The use of the rotifer Brachionus calyciflorus at the onset of exogenous feeding proved to be an efficient way to allow larvae to reach the size when they can feed upon Artemia nauplii. Embryonic development lasted 12-14 d at 20-21 C. Newly hatched larvae measured 5.1 mm total length (TL). The mouth and anus were opened; the eyes were pigmented; there were almost no yolk; and the pectoral fins were small and ...

The concept of botanical therapeutics has revitalized due to wide importance of plant derived pharmaceuticals. Therefore, the ameliorative characteristics of Ajuga bracteosa were studied. Total phenolic content, flavonoid content, antioxidant capacity, reducing power and free-radical scavenging activity were determined colorimetrically. Specific polyphenols were quantified by RP-HPLC analysis. Preliminary cytotoxicity was tested using brine shrimp lethality assay while antiproliferative activity against THP-1 and Hep-G2 cell lines was determined by MTT and SRB protocols respectively. Antileishmanial potential was assessed via MTT colorimetric method. To investigate antidiabetic prospect, α-amylase inhibition assay was adopted whereas disc diffusion method was used to detect likely protein kinase inhibitory, antibacterial and antifungal activities. Among fifteen different extracts, maximum total phenolic content (10.75 ± 0.70 μg GAE/mg DW), total reducing power (23.90 ± 0.70 μg AAE/mg DW) and total
At the level of the single cell, beings can trade genes back and forth horizontally with no regard for propriety or hygiene. So its not at all uncommon to see bacterial DNA stuffed full of foreign genes they picked up from their neighbors. But when you get into the multicellular world (i.e., the world of living things you can see with the naked eye) most of us get our genes the traditional way - from our parents and our parents parents and so on in a vertical ancestral lineage.. It seems that multicellular organisms typically keep their reproductive genomes carefully protected from foreign genes, preventing the kind of horizontal gene transfer seen in bacteria. So why would tardigrades, with their 1,000 cells, be so open to exotic genetic information? Boothby and his team theorized that the secret lay in the cryptobiotic process.. Apparently, when organisms dry out, their DNA breaks up into pieces. Luckily, tardigrades have a particular talent for stitching those pieces back together the ...

The developmental mode revealed by the minute larva of L. illecebrosa is similar to that in many extant eucrustaceans. Eucrustaceans (e.g., prawns, lobsters, brine shrimps, and barnacles) are so diverse morphologically that they share just a few specific and unique characters-one of which is the nauplius larva (14). Right after hatching, the nauplius (15) bears three pairs of functional appendages (14, 15). In subsequent stages, further segments and their appendages emerge from a growth zone in the posterior portion of the body (15, 16). The minute larva of L. illecebrosa resembles the late-stage metanauplius of certain eucrustaceans, especially anostracans (17), other branchiopods, and cephalocarids (14), in several aspects. First, the anterior (post-SGA segments 1-4) and posterior (post-SGA segments 5-14) portions of the body differ in outline (rounded vs. narrow and elongated; Fig. 3 and Fig. S2). This is not a result of flattening: The outline of soft-bodied fossils is not subject to ...
Fortunately there is a way to provide the nutrition of the algae without turning the display into an algae culture vessel. That is zooplankton; animals that feed on algae and condense its nutrition into compact bits of food suitable for coral and other invertebrate feeding. Probably the most well know critters are sea monkeys, brine shrimp, and they are simple to breed. Their basic problem is they lose their nutritional value less than a day after hatching when their yoke sac is exhausted. Feeding them algae culture is a great way to fatten them up and restore their food value. I won t go into breeding them as there are a ton of papers that detail the process. I ll provide links for those of you that wish to go that route at the end of this article. Another great food source is rotifers. These tiny critters are like individual grass catchers and can sweep the water column clear of algae in very short order, far faster than brine shrimp. Most rotifers are freshwater but a few of them are from ...

Mating in shrimps take place immediately after premating moult in matured female.Spawning occurs a few hours after mating. The incubation period of eggs lasts between 10-14 days depending upon the water temperature. The optimal water temperature being 25-35°C. At lower temperatures, the incubation period tales longer is stretching to more than 21 days. Hatching takes place due to body stretching of the zoea, which breaks the eggshell and comes out from the egg and starts swimming. Different larval rearing technologies such as static, clear, green water, closed or semi-closed, with or without circulation systems are practiced. The green water technique is generally reported to increase the post-larval production by 10-20°C over other techniques. But higher mortalities are encountered because of rise in pH and greater algal bloom. Also, there is enhanced increase in numbers of adult artemia, due to abundance of feed in green water, contributing to accumulation of ammonia in the culture medium. ...
Provided you are not directly adjacent to a saltwater disposal point, RO brine disposal is problematic and expensive. Brine concentration in traditional reverse osmosis membrane systems is limited by the amount of silica in the feed water. VSEPs vibratory oscillation prevents silica fouling, and thus VSEP is ultimately limited by osmotic pressure, not silica. Because of this unique capability, VSEP from Syngineering Water has become the market leader in non-thermal brine minimisation.. Syngineering Water - VSEP and Brine Minimisation.

SummaryWeight gain, length, and survival of Pacu (Piaractus brachypomus) larvae were analyzed after they were fed one of four diets. At 36 hours post-hatching larvae were fed for the first time and during three consecutive days: Artemia salinanauplii (T1), wild plankton filtered to 200 microns (T2),concentrated powder with 48% crude protein (T3) or no diet (fasting, T4). Animals were kept at a density of 70 larvae per liter. Statistically significant differences were observed with respect to the final weight for T1, T2, T3, and T4 (2.2 ± 0.3a, 1.7 ± 0.3b, 1.5 ± 0.3bc, 1.5 ± 0.2c mg, respectively) , final length (6.37 ± 0.29a, 0.20b ± 6.16, 5.95 ± 0.27c, 0.26c ± 5.87 mm, respectively), weight gain (0.77 ±0.39a, 0.31b ± 0.34, 0.16 ± 0.37bc, 0.08 ± 0.21 c mg, respectively) and length gain (0.39 ± 0.17A, 0.18± 0.15b, 0.16c ± -0023, -0102 ± 0.15c mm, respectively). The T1 diet had the best results for optimal growth, followed by T2. The survival rate was not statistically different ...

Family, Asclepiadeae) is implicated in a variety of ethno-medicinal therapies ranging form oral, skin, gastro-intestinal to respiratory problems. The effects of this plant on the sensitivity of micro-organisms need verification and its potential for cytotoxicity needs to be investigated. Thus, the anti-microbial and brine-shrimp lethality studies on the leaves and stem were carried out. The crude ethanolic extract of the stem and its ethylacetate fraction elicited good antibacterial activity against clinical strains of Bacillus subtilis ...
But there are other puzzles to the evolution of sex. And one involves sea monkeys. In a paper appearing in the Journal of Evolutionary Biology, Marta Maccari of the University of Hull and her colleagues describe a massive survey of brine shrimp from across Europe and Asia. They reared cysts from dozens of populations and closely examined the offspring over the course of two generations. The females in these populations can reproduce on their own. And yet in most of the populations they studied, they discovered a few males.. The males were exceedingly rare-around one in thousand in many cases, and around one in a hundred in a few. And yet they were healthy and fertile. The males couldnt mate with females of their own population, but they readily had sex with other species. Whats more, their hybrid offspring were healthy and fertile, too.. If asexual animal species are rare, species with asexual females and rare males are even more rare. Only a few other examples have turned up, such as certain ...
Sleeper goby I have a sleeper goby this is the only name I have . I would like to find the scientific name. It is bluish gray on the body , top fin is edged in red , lower fins are edged in white and behind the gill fins , his eyes are a very cloudy blue , he can be hand fed but at times has to make 2 or 3 tries to get the food into his mouth ( I think he has very poor vision) his tank has a pot large enough for him to hide in but he prefers to hide behind it vertically , he is very peaceful . he will eat anything but favors frozen blood worms , frozen brine shrimp and dried Tubifex worms. I have had him for about four years and he is thriving and seems content But I dont know for sure if I am doing everything right or is he just adapted to what Im doing. any help would be appreciated !

was studied in under laboratory conditions at a water temperature of 25-26 ℃, salinity of 30, and pH of 7.8-8.4. The embryogenesis of Portunus pelagicus was divided into six stages: cleavage, blastula, gastrula, nauplius, metanauplius, and protozoea. Embryogenesis lasted about 300 h post spawning. Eggs began superficial cleavage about 28 h after spawning when the nucleus appeared at the surface of the egg till the egg divided into 16 cells. The blastula stage was observed about 40 h post spawning and gastrula stage appeared when the presumptive endoderm and other cells near them invaginated. The fourth-stage of embryogenesis, nauplius, was characterized by three pairs of appendages appearing about 90 h post spawning, while metanauplius, the fifth-stage of embryogenesis, was characterized by five pairs of appendages, which appeared about 110 h post spawning. The sixth stage of embryogenesis was protozoea, which was characterized by seven pairs of appendages appearing about 140 h post spawning. ...

Eight marine cyanobacteria strains of the genera Cyanobium, Leptolyngbya, Oscillatoria, Phormidium, and Synechococcus were isolated from rocky beaches along the Atlantic Portuguese central coast and tested for ecotoxicity. Strains were identified by morphological characteristics and by the amplification and sequentiation of the 16S rDNA. Bioactivity of dichloromethane, methanol and aqueous extracts was assessed by the Artemia salina bioassay. Peptide toxin production was screened by matrix assisted laser desorption/ionization time of flight mass spectrometry. Molecular analysis of the genes involved in the production of known cyanotoxins such as microcystins, nodularins and cylindrospermopsin was also performed. Strains were toxic to the brine shrimp A. salina nauplii with aqueous extracts being more toxic than the organic ones. Although mass spectrometry analysis did not reveal the production of microcystins or other known toxic peptides, a positive result for the presence of mcyE gene was found in one

Background and objectives: Salvia species are important because of their medicinal, traditional and economical uses. They are used traditionally for treatment of several diseases. The genus Salvia is represented in the Iranian flora by 61 species of which, 17 are endemic. In the present study, the phytochemical and biological effects of two Iranian Salvia species have been evaluated. Methods: 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radicals scavenging activities of extracts of Salvia urmiensis Bunge and Salvia hydrangeawere evaluated. Total flavonoid and phenolic contents and brine shrimp lethality potential of the extracts were also determined. Results: Compared to podophyllotoxin (LC50 =42 µg/mL), the ethyl acetate extract of S. hydrangea demonstrated a significant cytotoxicity (LC50=36 µg/mL). The ethyl acetate extract of S. urmiensis was found to have significant antioxidant properties with IC50 value of 10.0±0.2 µg/mL. All tested
Alnus glutinosa, Fraxinus excelsior and Papaver rhoeas have long been used in folkloric medicine for the treatment of various ailments. As part of our continuing screening of plant extracts for activities, the extracts of A. glutinosa, F. excelsior and P. rhoeas have been screened for their antioxidant and antibacterial activities, as well as their general toxicity towards brine shrimps. Among the extracts, the methanol (MeOH) extract of F. excelsior displayed the highest level of antioxidant activity (RC50=1.35x10-2 mg/mL) and the dichloromethane (DCM) extract of P. rhoeas was the most toxic extract towards brine shrimps (LD50=2.4x10-2 mg/mL). The n-hexane and DCM extracts of F. excelsior and the MeOH extract of A. glutinosa were active (MIC values were within 1.25x10-1 and 1.00 mg/mL) against all 8 bacterial species tested, including methicillin-resistant Staphylococcus aureus (MRSA).
The seafloor is a unique environment, which allows insights into how geochemical processes affect the diversity of biological life. Among its diverse ecosystems are deep-sea brine pools - water bodies characterized by a unique combination of extreme conditions. The polyextremophiles that constitute the microbial assemblage of these deep hot brines have not been comprehensively studied. We report a comparative taxonomic analysis of the prokaryotic communities of the sediments directly below the Red Sea brine pools, namely, Atlantis II, Discovery, Chain Deep, and an adjacent brine-influenced site. Analyses of sediment samples and high-throughput pyrosequencing of PCR-amplified environmental 16S ribosomal RNA genes (16S rDNA) revealed that one sulfur (S)-rich Atlantis II and one nitrogen (N)-rich Discovery Deep section contained distinct microbial populations that differed from those found in the other sediment samples examined. Proteobacteria, Actinobacteria, Cyanobacteria, Deferribacteres, and ...

Centella asiatica (Umbelliferae) and Aegle marmelos (Rutaceae) are widely used as a vegetable and a fruit respectively. These two plants are used in Ayurvedic and indigenous medicinal systems in Sri Lanka.Earlier researchers have reported the effect of aqueous extracts of these two plants on the classical and alternative pathways of activation of human complement in vitro. Activity direvted fractionation of the aqueous extracts indicated that most of the activity was condined to the polysaccharide fraction. This thesis reports the preliminary chemical analysis of the polysaccharide fraction of Centella asiatica and Aegle marmelos. These polysaccharides were hydrolysed and methanolysed. T.L.C and H.P.L.C. analysis were done for analyzing their monomer composition. The immunomodulating activity and biological activity of these fractions using the Artemia bio assay were studied ...
