Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. PLANTS, which convert SOLAR ENERGY to food by PHOTOSYNTHESIS, are the primary food source. In a predator chain, a plant-eating animal is eaten by a larger animal. In a parasite chain, a smaller organism consumes part of a larger host and may itself be parasitized by smaller organisms. In a saprophytic chain, microorganisms live on dead organic matter.Biological Evolution: The process of cumulative change over successive generations through which organisms acquire their distinguishing morphological and physiological characteristics.Water Movements: The flow of water in enviromental bodies of water such as rivers, oceans, water supplies, aquariums, etc. It includes currents, tides, and waves.Electric Organ: In about 250 species of electric fishes, modified muscle fibers forming disklike multinucleate plates arranged in stacks like batteries in series and embedded in a gelatinous matrix. A large torpedo ray may have half a million plates. Muscles in different parts of the body may be modified, i.e., the trunk and tail in the electric eel, the hyobranchial apparatus in the electric ray, and extrinsic eye muscles in the stargazers. Powerful electric organs emit pulses in brief bursts several times a second. They serve to stun prey and ward off predators. A large torpedo ray can produce of shock of more than 200 volts, capable of stunning a human.

Fish - Kosherquest.org - Online Kashrus Informationeat of the fishes, all that have fins and scales…" (Vayikrah XI:9-12) Bony tubercles and plate or thorn-like scales that can be removed only by removing part of the skin are not considered scales in this context. Some fish that have such scales, such as eels, lumpfish, shark, sturgeon, and swordfish, are not kosher. All shellfish and mammals (such as whales, and dolphins) are not kosher. Only the eggs of kosher fish, such as fish roe or caviar, are allowed, therefore supervision is necessary. Care must be taken when buying fresh, whole fish, filleted, or frozen, because of the possibility of substitution by non-kosher fish or of contamination by remnants of non-kosher fish from knives and cutting boards. Fish sticks have three problems: the fish, the oil, and the frying utensils and equipment (which is usually used for non-kosher fish as well as kosher fish). Smoked fish is frequently soaked in brine and then smoked along with non-kosher fish. According to Jewish law, this soaking and ...
Fish Handling and GearFish may die after release for a variety of reasons. The most common causes of post-release mortality are physiological stress on the fish resulting from struggle during capture, injuries caused by the hook, and mishandling of the fish by the angler.. Unfortunately, some fish may die after release even though they appear unharmed and despite efforts by the angler to revive the fish.. Fish that struggle intensely during capture are usually exhausted and stressed from the accumulation of excessive amounts of lactic acid in their muscles and blood. The stress of capture may be more severe for larger fish such as tarpon, therefore, using the proper weight-class tackle, landing your catch quickly, and releasing the fish as quickly as possible increases the fish's chance of survival. Bringing an exhausted fish out of the water is like asking a triathlon winner to jump back in the water and hold their breath---they both need oxygen to recover!. Fish that are reeled to the surface from deep water may ...
Extinction, survival or recovery of large predatory fishes | Philosophical Transactions of the Royal Society B: Biological...Large predatory fishes have long played an important role in marine ecosystems and fisheries. Overexploitation, however, is gradually diminishing this role. Recent estimates indicate that exploitation has depleted large predatory fish communities worldwide by at least 90% over the past 50-100 years. We demonstrate that these declines are general, independent of methodology, and even higher for sensitive species such as sharks. We also attempt to predict the future prospects of large predatory fishes. (i) An analysis of maximum reproductive rates predicts the collapse and extinction of sensitive species under current levels of fishing mortality. Sensitive species occur in marine habitats worldwide and have to be considered in most management situations. (ii) We show that to ensure the survival of sensitive species in the northwest Atlantic fishing mortality has to be reduced by 40-80%. (iii) We show that rapid recovery of community biomass and diversity usually occurs when ...
FISH WONTON W/ ANCHOVY, GARLIC , TABASCO - Lady and Pups - an angry food blogimported Italian goods), and they turned out to be little drops of afternoon delights. So why fish wonton? Why fish? See, I don't know about you, but when other people stock up their freezer with prime rib-eye steaks from Cosco, I do mine with frozen catfish fillets. I don't know why. Cheapness, possibly. Don't make me admit that I like frozen catfish. I'm supposed to have taste-buds of high caliber. How dare you. No, the point is, I was saying… as I was cleaning out my frozen fish tank, I thought, fish wonton, why not?. Ground fish, here in Asia, is actually quite a common ingredient with wide applications. What it lacks in meaty-ness, it gains in an uniquely light, soft and creamy texture which resembles between ricotta filling and French quenelles. It makes a wonton that is light in body and texture, with a particular sweetness in its gentle nature. To dress it up, I used a deeply savory olive oil with salty specks of anchovies and crispy garlic, brightened with fresh grated ginger, chopped ...
Ken Ham on Tiktaalik roseae - Dispatches from the Creation WarsIn the case of the fish to amphibian transition, we're talking about the very first amphibians to appear on the earth. Prior to about 365 million years ago, there were no amphibians on this planet, no terrestrial animals at all other than insects (which had only appeared about 400 million years ago). The earliest amphibian tetrapods looked remarkably like lobe-finned fish, called sarcopterygians, which led scientists to posit that they probably evolved from a species in that group. But it doesn't end there; we can get more specific. The earliest amphibians were not just closest to lobe-finned fish but to a particular subset of those fish known as osteolepiform. Osteolipiform fish share a trait with amphbians called a choana, an opening between the nostrils and the mouth that is essential for breathing air. In the water, it's used for smell, not for breathing, but it allows air to pass into the body through the nostrils so on land it could be adapted for breathing. Amphibians and osteolipiforms ...
Scat, Scatophagus argus Profile, with care, maintenance requirements and breeding information for your tropical fishScats . I am keeping all types Silver, Green, and Red. They are kept in a 20 gallon tank with monodactyls, both types. I use lots of filtration in a 20 gal tank and only three fish, to allow for growth. The Mono Sebae is huge-ten inches, and was aggressive enough to deter two small argentus. I bought four mollys, and two black finned sharks to break up the fighting, added a small silver scat, and then pulled out the dither fish (the mollys and the black finned shark-cats). This leaves me with two tanks of three fish each. In one a Mono argentus with a mono sebae and silver scat: the other tank holds two scats, one green (very large) and the other red, with the addition of a hefty mono argentus. There should be no problem with these guys. I can get them to eat anything really; they are funny swimmers in that they go horizontal, they duck under things and they come to the hand quite well. You can get them to eat frozen peas, by first cooking them a bit and breaking the shells with you finger; they ...

These truly fresh shad are then offered for sale. Thousands of others visit Lambertville for the broader festivities including tastes of shad (planked, roe, etc), environmental programs, and art gallery-hopping with over-the-top shad themes ...
SierraClubGreenHome: March 2009For decades, health advocates have exhorted us to eat more fish. It's low in saturated fat, rich in healthy omega-3 fatty acids, and a good source of protein, minerals, and vitamins. But these days the arguments for eating fish aren't so cut and dried. Many species, especially tuna, swordfish, and shark, are poisoned with mercury (much of which comes from emissions from coal-burning power plants). Mercury contamination is especially harmful to developing fetuses.The environmental news about fish is equally dire. According to WWF, an international conservation group, the populations of all species currently fished for food will collapse by 2048 if humans don't dramatically change our fishing and fish consumption practices.Unfortunately, fish farming has not turned out to be a panacea. Huge quantities of wild fish are caught to feed farmed fish, exacerbating overconsumption problems. Waste from fish farms contaminates the oceans, and the flesh of farmed fish may contain artificial dyes, as well as ...
The Angry Lab Rat: Fish That Will Eat You Alive And Make You Healthier At The Same TimeBack in 1917, a shepherd dipped his wounded leg into the hot water. These little fish, which are a little under 4 inches, or 9.7 cm, long, nibbled off the dead flesh from the wound. "Miraculously" his wound healed nicely. The fish are of the species Garra rufa, and became known as "doctor fish." By the 1950s, a local family enclosed the hot pool and a population of the fish in it, then started charging people for the right to let the fish eat their wounds. Normally the fish would move back and forth between the hot water (34 degrees C, or 93 degrees F) and an adjoining cool stream, eating algae and insects. But almost nothing grows in the hot spring, so the fish are very eager to eat human flesh as a food source. They only pick off the dead skin, though, and it isn't painful ...

Is Eating Raw Fish Safe and Healthy? | AlternetCooking kills bacteria and parasites that can cause disease. So is it safe to eat sushi? There are several practical reasons people cook fish before eating it, rather than simply serving it raw.Most importantly, cooking kills bacteria and parasites that can cause disease. Nevertheless, some people prefer the texture and taste of raw fish. It is especially popular in Japan as part of dishes like sushi and sashimi.But how safe is raw fish? This article reviews the risks and benefits. Types of Raw Fish DishesRaw fish dishes are growing in popularity. Here are a few examples:
Colorful and Bizarre New Fish Discovered - Looks Delicious Scientists Say - ZooillogixA completely new family of fishes may have been discovered in the coral beds of Indonesia. Dive company owners, Buck and Fitrie Randolph of Maluku Divers spotted the fish in January but waited to photograph additional specimens before contacting the experts. Interviewed by Seattle PI, University of Washington ichthyologist Ted Pietsch, who specializes in anglerfish, said it was unlike anything he had ever seen, sputtering "I'm still thrilled. It's an incredible thing. It's remarkable.". The pink-and-tan striped frogfish cannot be identified by any fish experts so far. While Pietsch is relatively sure it is a type of frogfish, given the sheath on the eggs and arm-like fins, there are some strong differentiators: It lacks a lure, has tiny pelvic fins and, most bizarrely, has a flat face with forward facing eyes. Typically a fish's eyes are on opposite sides of their head rather than side by side like human eyes. This means it is possible that this fish has binocular vision for improved depth ...

What Does Science Say? Bioavailability of Triglyceride vs. Ethyl Ester Forms of Fish OilConsumers and health professionals like concentrated fish oil products. Higher doses of EPA and DHA are often required to achieve desired nutrition and health benefits. Concentrated fish oil products can provide double or more of the amount of EPA and DHA than regular fish oil but not at double the price. Concentrated fish oil products offer more omega-3 in fewer capsules and are often a better value.. Manufacturing concentrated fish oil: EE and rTG forms. To begin, the three types of fatty acids (saturated, monounsaturated, or polyunsaturated) in the triglyceride are liberated from glycerol and attached to an ethyl alcohol and become ethyl ester (EE) fatty acids.

Fish Are Animals Who Do ThingsSocial learning is illustrated by the migrations of the surgeon fish (Acathurus nigrofuscus), described in detail by Arthur A. Myrberg Jr. in 1998. These fish leave their territories all over the lagoon, and travel in single file through paths in the coral to their traditional spawning grounds. They go and return along the same paths each night at precisely the same time, as I saw in the local lagoon, year after year. Their spawning ground was the only place along the lagoon's border where the outflowing current was exactly balanced by the incoming surge, so that the huge cloud of spawn that they left in the gathering night, stayed in place. These short term migrations had been shown to be the result of social learning; each generation of fish learned from its elders where to go to spawn, and when ...
Diseases And Parasites | Green AquariumSome of the things you should look for however when purchasing a new fish are:. 1. Behavior- How is it swimming? Is it interacting with the other fish?. Take some time to watch the fish you have your eye on. If it is swimming erratically or off-balance you need to look for another fish. Is it scratching its body against the rocks or substrate? If so you don't want it either. Is it hidden in a corner and not active? All of these are cause for concern and you should refrain from purchasing. Trust me I know how tempting it is. You will ignore me much as I have and do it anyway. I just did and I regret it wholeheartedly.. 2. Condition- How does the fish look?. Visually inspect the fish for lesions, imperfections, spots, dots, bumps you get the idea. Are the fins torn? Maybe you think it is just from another fish picking on it, or perhaps it has parasites that are eating away at its tissue. All that can come of us purchasing sick fish is that our local stores will keep stocking them. After all it ...

(2/5700) Three receptor genes for plasminogen related growth factors in the genome of the puffer fish Fugu rubripes.
Plasminogen related growth factors (PRGFs) and their receptors play major roles in embryogenesis, tissue regeneration and neoplasia. In order to investigate the complexity and evolution of the PRGF receptor family we have cloned and sequenced three receptors for PRGFs in the teleost fish Fugu rubripes, a model vertebrate with a compact genome. One of the receptor genes isolated encodes the orthologue of mammalian MET, whilst the other two may represent Fugu rubripes orthologues of RON and SEA. This is the first time three PRGF receptors have been identified in a single species. (+info)
(3/5700) Subunit dissociation in fish hemoglobins.
The tetramer-dimer dissociation equilibria (K 4,2) of several fish hemoglobins have been examined by sedimentation velocity measurements with a scanner-computer system for the ultracentrifuge and by flash photolysis measurements using rapid kinetic methods. Samples studied in detail included hemoglobins from a marine teleost, Brevoortia tyrannus (common name, menhaden); a fresh water teleost, Cyprinus carpio, (common name, carp); and an elasmobranch Prionace glauca (common name, blue shark). For all three species in the CO form at pH 7, in 0.1 M phosphate buffer, sedimentation coefficients of 4.3 S (typical of tetrameric hemoglobin) are observed in the micromolar concentration range. In contrast, mammalian hemoglobins dissociate appreciably to dimers under these conditions. The inability to detect dissociation in three fish hemoglobins at the lowest concentrations examined indicates that K 4,2 must have a value of 10(-8) M or less. In flash photolysis experiments on very dilute solutions in long path length cells, two kinetic components were detected with their proportions varying as expected for an equilibrium between tetramers (the slower component) and dimers (the faster component); values of K 4,2 for the three fish hemoglobins in the range 10(-9) to 10(-8) M were calculated from these data. Thus, the values of K 4,2 for liganded forms of the fish hemoglobins appear to be midway between the value for liganded human hemoglobin (K 4,2 approximately 10(-6) M) and unliganded human hemoglobin (K 4,2 approximately 10(-12) M). This conclusion is supported by measurements on solutions containing guanidine hydrochloride to enhance the degree of dissociation. All three fish hemoglobins are appreciably dissociated at guanidine concentrations of about 0.8 M, which is roughly midway between the guanidine concentrations needed to cause comparable dissociation of liganded human hemoglobin (about 0.4 M) and unliganded human hemoglobin (about 1.6 M). Kinetic measurements on solutions containing guanidine hydrochloride indicated that there are changes in both the absolute rates and the proportions of the fast and slow components, which along with other factors complicated the analysis of the data in terms of dissociation constants. Measurements were also made in solutions containing urea to promote dissociation, but with this agent very high concentrations (about 6 M) were required to give measureable dissociation and the fish hemoglobins were unstable under these conditions, with appreciable loss of absorbance spectra in both the sedimentation and kinetic experiments.

(5/5700) Importance of air and water breathing in relation to size of the African lungfish Protopterus amphibius Peters.
1. Oxygen uptakes from air and water have been measured in relation to weight of the African lungfish Protopterus amphibius Peters. 2. Combined O2 uptake from air and water ranged from 60 ml O2 kg-1 h-1 STPD, in a 3-7 g specimen, to 30 ml O2kg-1 h-1, in a 255 g specimen. 3. While the combined O2 uptake changed by a factor of 2, within the weight range under study, the aquatic O2 uptake changed 8-fold within the same range. The smaller fish satisfy 70% of their O2 requirement by aquatic breathing compared to 10-15% in the grown specimens. 4. The pattern of bimodal breathing in P. amphibius is discussed in relation to the natural habitat of the species. (+info)
(6/5700) Midbrain combinatorial code for temporal and spectral information in concurrent acoustic signals.
All vocal species, including humans, often encounter simultaneous (concurrent) vocal signals from conspecifics. To segregate concurrent signals, the auditory system must extract information regarding the individual signals from their summed waveforms. During the breeding season, nesting male midshipman fish (Porichthys notatus) congregate in localized regions of the intertidal zone and produce long-duration (>1 min), multi-harmonic signals ("hums") during courtship of females. The hums of neighboring males often overlap, resulting in acoustic beats with amplitude and phase modulations at the difference frequencies (dFs) between their fundamental frequencies (F0s) and harmonic components. Behavioral studies also show that midshipman can localize a single hum-like tone when presented with a choice between two concurrent tones that originate from separate speakers. A previous study of the neural mechanisms underlying the segregation of concurrent signals demonstrated that midbrain neurons temporally encode a beat's dF through spike synchronization; however, spectral information about at least one of the beat's components is also required for signal segregation. Here we examine the encoding of spectral differences in beat signals by midbrain neurons. The results show that, although the spike rate responses of many neurons are sensitive to the spectral composition of a beat, virtually all midbrain units can encode information about differences in the spectral composition of beat stimuli via their interspike intervals (ISIs) with an equal distribution of ISI spectral sensitivity across the behaviorally relevant dFs. Together, temporal encoding in the midbrain of dF information through spike synchronization and of spectral information through ISI could permit the segregation of concurrent vocal signals. (+info)
(7/5700) Characterization of K+ currents underlying pacemaker potentials of fish gonadotropin-releasing hormone cells.
Endogenous pacemaker activities are important for the putative neuromodulator functions of the gonadotropin-releasing hormone (GnRH)-immunoreactive terminal nerve (TN) cells. We analyzed several types of voltage-dependent K+ currents to investigate the ionic mechanisms underlying the repolarizing phase of pacemaker potentials of TN-GnRH cells by using the whole brain in vitro preparation of fish (dwarf gourami, Colisa lalia). TN-GnRH cells have at least four types of voltage-dependent K+ currents: 1) 4-aminopyridine (4AP)-sensitive K+ current, 2) tetraethylammonium (TEA)-sensitive K+ current, and 3) and 4) two types of TEA- and 4AP-resistant K+ currents. A transient, low-threshold K+ current, which was 4AP sensitive and showed significant steady-state inactivation in the physiological membrane potential range (-40 to -60 mV), was evoked from a holding potential of -100 mV. This current thus cannot contribute to the repolarizing phase of pacemaker potentials. TEA-sensitive K+ current evoked from a holding potential of -100 mV was slowly activating, long lasting, and showed comparatively low threshold of activation. This current was only partially inactivated at steady state of -60 to -40 mV, which is equivalent to the resting membrane potential. TEA- and 4AP-resistant sustained K+ currents were evoked from a holding potential of -100 mV and were suggested to consist of two types, based on the analysis of activation curves. From the inactivation and activation curves, it was suggested that one of them with low threshold of activation may be partly involved in the repolarizing phase of pacemaker potentials. Bath application of TEA together with tetrodotoxin reversibly blocked the pacemaker potentials in current-clamp recordings. We conclude that the TEA-sensitive K+ current is the most likely candidate that contributes to the repolarizing phase of the pacemaker potentials of TN-GnRH cells. (+info)
(8/5700) Activities of citrate synthase, NAD+-linked and NADP+-linked isocitrate dehydrogenases, glutamate dehydrogenase, aspartate aminotransferase and alanine aminotransferase in nervous tissues from vertebrates and invertebrates.
1. The activities of citrate synthase and NAD+-linked and NADP+-linked isocitrate dehydrogenases were measured in nervous tissue from different animals in an attempt to provide more information about the citric acid cycle in this tissue. In higher animals the activities of citrate synthase are greater than the sum of activities of the isocitrate dehydrogenases, whereas they are similar in nervous tissues from the lower animals. This suggests that in higher animals the isocitrate dehydrogenase reaction is far-removed from equilibrium. If it is assumed that isocitrate dehydrogenase activities provide an indication of the maximum flux through the citric acid cycle, the maximum glycolytic capacity in nervous tissue is considerably greater than that of the cycle. This suggest that glycolysis can provide energy in excess of the aerobic capacity of the tissue. 2. The activities of glutamate dehydrogenase are high in most nervous tissues and the activities of aspartate aminotransferase are high in all nervous tissue investigated. However, the activities of alanine aminotransferase are low in all tissues except the ganglia of the waterbug and cockroach. In these insect tissues, anaerobic glycolysis may result in the formation of alanine rather than lactate. (+info)
