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 ...

One of the most helpful additions to an aquarist breeders kit is a phial of dried brine shrimp eggs. These eggs arent in themselves a food, but when hatched out they offer an outstanding early live food diet.. You are able to hatch the eggs in two-pound jam jars, in which a saline answer has been added. To make the answer, mix a tablespoon of salt with a pint of water thoroughly, shaking the container, then permit it to settle and strain via a piece of muslin to remove any sediment. Pour this water into the jar and sprinkle some eggs on the surface, and then stand the jar in an aquarium to maintain at a temperature of 75°-80°F. This serves as an incubator. The eggs will hatch in 48 hours, leaving the small shrimps dancing about in the container. To feed, strain the water via a pad made of a number of thicknesses of muslin, and rinse in the aquarium. You should only make up quantities sufficient for one feeding in every jar, as the collection of newly hatched shrimps can only be done by ...
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 ...
Genealogical concordance is a critical overlay of all phylogenetic analyses, irrespective of taxonomic level. To assess such patterns of congruence we have compiled and derived sequence data for two mitochondrial (16S rRNA, COI) and two nuclear (ITS1, p26) markers in 14 American populations of the hypersaline branchiopod Artemia franciscana. Cladistic analysis revealed three reciprocally monophyletic mitochondrial clades. For nuclear DNA, incomplete lineage sorting was evident presumably as a result of slower coalescence or male-mediated dispersal. Our findings capture the genealogical interval between gene splitting and population divergence. In this sense, strong indications are provided in favour of a superspecies status and ongoing speciation in A. franciscana.
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.

The brine shrimp Artemia comprises a group of seven to nine species very likely to have diverged from an ancestral form living in the Mediterranean area about 5.5 million years ago.[6]. The Laboratory of Aquaculture & Artemia Reference Center (ARC) at Ghent University possesses the largest known Artemia cyst collection, a cyst bank containing over 1,700 Artemia population samples collected from different locations around the world.[7]. Artemia is a typical primitive arthropod with a segmented body to which is attached broad leaf-like appendages. The body usually consists of 19 segments, the first 11 of which have pairs of appendages, the next two which are often fused together carry the reproductive organs, and the last segments lead to the tail.[8] The total length is usually about 8-10 millimetres (0.31-0.39 in) for the adult male and 10-12 mm (0.39-0.47 in) for the female, but the width of both sexes, including the legs, is about 4 mm (0.16 in). The body of Artemia is divided into head, ...

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.

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.. Differences in the enrichment efficiencies through time were found not only between liposome and emulsion based ...
Mackeen, M.M.; Khan, M.N.; Zainudin Samadi; Lajis, N.H., 2000: Brine shrimp toxicity of fractionated extracts of Malaysian medicinal plants
Chemobehavioural phenotypic analysis using small aquatic model organisms is becoming an important toolbox in aquatic ecotoxicology and neuroactive drug discovery. The analysis of the organisms behavior is usually performed by combining digital video recording with animal tracking software. This software detects the organisms in the video frames, and reconstructs their movement trajectory using image processing algorithms. In this work we investigated the impact of video file characteristics, video optimization techniques and differences in animal tracking algorithms on the accuracy of quantitative neurobehavioural endpoints. We employed larval stages of a free-swimming euryhaline crustacean Artemia franciscana,commonly used for marine ecotoxicity testing, as a proxy modelto assess the effects of video analytics on quantitative behavioural parameters. We evaluated parameters such as data processing speed, tracking precision, capability to perform high-throughput batch processing of video files. Using a

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. ...

The abundance and distribution of shrimp larvae were studied along four transects off West Greenland in June-July 1996. Zooplankton samples and vertical profiles of temperature, salinity, and fluorescence were obtained along the transects in order to relate larval distribution to hydrographical and biological characteristics. Eight species of shrimp larvae occurred in the samples; Pandalus montagui and Pandalus borealis were the most numerous constituting 61 and 29% of the larvae, respectively. Other species of shrimp larvae were, in declining order of abundance, Sabinea septemcarinata, Lebbeus groenlandicus, Spirontocaris spinus, Eualus galmardi, Pontophilus (norvegicus?), and Argis dentata. Pandalus shrimp larval density showed a significant positive association with mean fluorescence (5-80 m), but no association with mean temperature, or densities of copepod eggs and nauplii. However, most larvae were caught in water columns with temperatures and salinities of ~2°C. and ~33 psu, ...

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 ...

TY - JOUR. T1 - Determination and toxicity evaluation of the generated products in sulfamethoxazole degradation by UV/CoFe2O4/TiO2. AU - Gong, Han. AU - Chu, Wei. PY - 2016/8/15. Y1 - 2016/8/15. N2 - The photodegradation of sulfamethoxazole (SMX) under UV radiation with a recyclable catalyst CoFe2O4/TiO2was examined. The reaction mechanism during the treatment was determined. The toxicity of the degradation intermediates to aquatic organisms, including the green alga Chlorella vulgaris and the brine shrimp Artemia salina was investigated. SMX was completely removed and about 50% TOC was degraded in 5 h. Sixteen intermediates were detected, from which four of them were reported for the first time in this study. Four main decay pathways, i.e., hydroxylation, cleavage of SN bond, nitration of amino group, and isomerization were proposed. About 45% of the total mass sulfur source transformed to sulfate ion, and around 25%, 1%, and 0.25% of the total nitrogen transformed to ammonium, nitrogen, and ...
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, ...

We studied the feeding behavior of the nauplii and adult females of the marine cyclopoid copepod Oithona davisae in the laboratory. Functional response experiments showed that O. davisae can feed on a broad size range of prey but that high clearance rates only occur in a narrow prey size range. Neither the nauplii nor the females were able to feed on Nannochloropsis oculata 2.5µm, but , 4 µm prey were ingested. The highest clearance rates occurred when the nauplii and females were offered the dinoflagellate Oxyrrhis marina and the ciliate Strombidium sulcatum, respectively. O. davisae females preyed on Acartia grani nauplii but not on nauplii of their own species. Optimal prey : predator size ratios were similar for the nauplii and the females ∼10ofthepredator′sbodylength and were higher than those reported for suspension-feeding calanoid copepods 2-6. The finding that the nauplii and females of O. davisae feed on relatively larger prey appears to be a consequence of their strict ...
Abstract:. Introduction: Terminalia spp. are characterised by their high levels of antioxidant phytochemicals and several species have anticancer activity. This study examines the anti-proliferative activity of T. sericea leaf extracts against Caco2 and HeLa carcinoma cell proliferation. Methods: Solvent extracts were prepared from T. sericea leaves and their antioxidant capacities were determined by the DPPH free radical scavenging assay. Anti-proliferative activities against Caco2 and HeLa cancer cells were determined by an MTS based cell proliferation assay. Toxicity was determined using the Artemia franciscana nauplii bioassay. Results: The methanolic and aqueous T. sericea leaf extracts displayed high antioxidant capacities (equivalent to 150 and 340 mg of ascorbic acid per gram of plant material extracted respectively). In contrast, the ethyl acetate, chloroform and hexane extracts had relatively low antioxidant contents (≤5 mg of ascorbic acid equivalents per gram of plant material ...
Meal frequency is a key parameter in fish larviculture, especially in highly cannibalistic species. Knowledge of the biological bases of cannibalism (growth capacity of cannibals, morphological constraints on cannibalism, prey size preference) can help predicting the risks of cannibalism for different feeding schedules under culture conditions. This study relied on the day-by-day analysis of prey size preference and bioenergetics of individual cannibals of the catfish Pseudoplatystoma punctifer (8-65 mm standard length, SL, 0.5-400 mg dry mass, DM) at 28.5 °C under 12L:12D. The results were equated with the ontogenetic variations of morphological factors (head and mouth width) and feed efficiency of larvae feeding on Artemia nauplii, in order to calculate the risks of cannibalism among fish fed 2-7 daily meals. The predation capacities of P. punctifer were highest at 8 mm SL and decreased in larger fish (largest prey = 86% and 70% SL in fish of 8 and ,30 mm SL, respectively). Cannibals of ...

It has been observed that the various part of Baccaurea ramiflora plant is used in rheumatoid arthritis, cellulitis, abscesses, constipation and injuries. This plant also has anticholinergic, hypolipidemic, hypoglycemic, antiviral, antioxidant, diuretic and cytotoxic activities. The present studyaimed to assess the cytotoxic, analgesic, anti-inflammatory, CNS depressant and antidiarrheal activities of methanol extract of Baccaurea ramiflora pulp and seeds in mice model. The cytotoxic activity was determined by brine shrimp lethality bioassay; anti-nociceptive activity was determined by acetic acid-induced writhing, formalin- induced licking and biting, and tail immersion methods. The anti-inflammatory, CNS depressant and anti-diarrheal activities were assessed by carrageenan-induced hind paw edema, the open field and hole cross tests, and castor oil-induced diarrheal methods, respectively. The data were analyzed by one way ANOVA (analysis of variance) followed by Dunnetts test. In brine shrimp
Nitrogenous heterocyclic compounds, oxindoles especially isatins and related heterocyles have excellent antifungal, anti-inflammatory, antimicrobial and anticancer activities. Oxindoles keto lactams (1-3) were synthesized according to modified Sandmayer method and their N-acetylated compounds (4-6) gave diazo-biphenyls (7-10) through ring cleavage and consequent cyclization reaction. Bis-amide (11), and Schiff-base (12) were synthesized from oxindoles respectively. The investigation of cytotoxicity of the synthesized compounds was carried out against brine shrimp lethality bioassay. In our present investigation some of the synthesized compounds such as halogen substituted acetylisatins (4-6) and the ring extended diazo-biphenyls, (7-10) have been shown to exhibit strong cytotoxic effect.. Key words: diazo-biphenyls; oxindoles; cytotoxicity; brine shrimp. DOI: 10.3329/dujps.v9i1.7423. Dhaka Univ. J. Pharm. Sci. 9(1): 1-6, 2010 (June). ...

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 ...
In this study, we have evaluated the antimicrobial and cytotoxic activities of the aqueous, Hexane, ethyl acetate and methanolic extracts of Diospyros canaliculata. The study of the antimicrobial activity has been achieved by the Agar well diffusion method for the determination of the the inhibition zones and the liquide dilution method for the determination of the minimal inhibition concentraion of the different extracts on ten bacterial strains implicated in several human infections. Brine Shrimp lethality bioassay was used in the cytotoxicity investigations. The results showed a weak inhibitory activity of the aqueous extract, on 9 of the 10 microbial strains. Ethyl acetate and methanolic extracts also presented a weak inhibitory effects though active on all the tested bacterial strains. On the other hand a strong antibacterial activity of the hexane extrat was observed on all the tested pathogenic agents. Cytotoxic assay showed that the different extracts were non toxic. The LD50 has been ...

Sea Monkeys, or brine shrimp (of the Artemia Genus) are very small organisms that live in marine environments. However, you wont find them in the ocean but rather in inland saltwater lakes. A unique characteristic of brine shrimp allows them to produce eggs, or cysts, that can remain dormant for long periods of time. As a result they are commonly used in the aquarium hobby as a food source for other organisms as well as to test toxicity levels. ...
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 ...

This week it was widely reported that Mozilla-owned web browser Firefox is switching its default search engine from Google to Yahoo. Seen by many as a win for Yahoo (though not a significant loss for Google) it has also been suggested in this report by NPRs Marketplace that it may be more values-based, and that privacy concerns could have played a role. According to the report, Yahoo has promised to honor Mozillas do not track policy, based on the companys founding principles that individuals security and privacy on the Internet are fundamental and must not be treated as optional.. 2014 has been a big year for privacy concerns. From the consternation at the beginning of the year around the Facebook research which manipulated some users news feeds to Ubers recent PR stumble regarding its own privacy policies - which has led them to hire a privacy czar - it feels like we have reached a privacy tipping point.

A new 1907 Landing Utility Vessel (LUV), built by Dutch shipbuilder Nauplius Workboats, has been handed over to Marine Harvest Scotland. The LUV, a crossover between a landing craft and a Multi-Cat, is well-received by its new owner: one sister vessel and three larger versions are currently being built. Marine Harvest Scotland ordered two 1907 LUVs, designed by Argos Engineering. The first vessel has already been handed over to Marine Harvest Scotland at their Rum site, while the second vessel will be delivered in September. The 1907 LUV distinguishes itself by a special layout: a work deck on starboard along the entire ships length, facing the side of the pen. This was realised by placing the superstructure at portside, says Gerrit Knol, technical director of Nauplius Workboats. There is also enough space for a large crane, an HS Marine AK40 HE4.. An extra addition to the original design of the 19 meter long workboat, used as a site boat at the Marine Harvest site Rum, is an AKVA net washer ...

The pinecone fish, sometimes called the pineapple fish, is a tough little deep-sea dweller that grows to about 5 inches or 13 centimeters in length. It is covered with bright yellow to orange hard scales, called scutes, that are vibrantly outlined in black accentuating its pinecone-like appearance. Its sharp spines and locking dorsal and pelvic fins discourage predators. If they attempt to swallow the swimming pinecone, they risk getting it stuck in their throat.. It prefers to live in rocky areas of the deep ocean with reefs and caves where it can hide during the day. The fish emerges at night to feed on brine shrimp, small fish and plankton that it attracts to its mouth by way of two glowing organs located on its chin. These organs house bioluminescent bacteria that glow an orange-yellow during the day and dim to a bluish-green at night. The bacteria benefits by having a host that provides it with an advantageous place to grow. The pinecone fish benefits by using the the glow to attract meals. ...

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 ...
There is no doubt that flamingoes love the Salar de Atacama and salt flats elsewhere. These birds love them of course not for the high salinities of their brines or beautiful settings, but for the shrimps and algae that live in them. For eons, flamingoes come there to feed and breed, and will do so as long as salt flats are around.. We humans however like salt flats for other reasons, and it is definitely not for its tiny shrimps, nor the algae. Of course we love them for seeing the flamingoes, but more importantly we like them for the elements that are contained in the brines that make them. The brines on the surface are thereby not too much of interest, but rather those that are held in underground aquifers. So what are exactly brines? In general brines are formed when water from the surrounding mountains enter a restricted basin (ie. no exit) either on the surface or underground. Since the water enters a basin in a desert, the water slowly evaporates and the dissolved salts within it increase ...

Capital breeders must balance the energetic requirements of cellular function and the cost of reproduction. The subarctic copepod Neocalanus flemingeri, a small planktonic crustacean, depends on a short annual phytoplankton bloom to acquire the energy needed to support a non-feeding adult female that enters a period of diapause prior to spawning 5 to 7 months later. After emergence from diapause, the reproductive program takes 2 months starting with germline development. In this study, the regulation of genes involved in energy utilization and cellular maintenance were investigated using RNA-Seq as females progressed from diapause to end-of-life. Hierarchical clustering of expression profiles from 61 individual females identified four major transitions in transcriptional profiles along a timeline spanning from diapause to spawning and post-reproduction. The clusters were analyzed statistically for differential gene expression followed by functional analyses. The transition from diapause to post-diapause
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 ...
