Fish have a unique position with respect to their taxonomic and phylogenic status among vertebrates and occupy an important place in vertebrate’s genealogy. Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary (1 – 2 ºC) as ambient temperatures change. Majority of siluroid fish are economically important for human consumption. Protein and vitamins content in fish flesh varies from high to moderate and make it as rich source of protein diet. Fishes of siluroid order ranges from freshwater to brackish waster to swamps and marshes both in temperate and tropical regions. The freshwater catfish, Clarias batrachus from siluroid order is a native specie of tropical south-east Asia and commonly known as “Magru” in India…
environment lead Pounder and his colleagues to investigate if doing so would be just as beneficial to captive fish. Fish are a hugely exploited research model as millions of tons of fish are farmed across the UK. Despite the massive commercial production occurring, inadequate research has been done on improving fish welfare in stressful situations. The large growth of the aquaculture industry should be synonymous with research about how to remedy production problems and facilitate humane…
As catches have gradually become smaller, so the mesh sizes used in fishing nets have decreased, allowing smaller and smaller fish to be caught. Many of these are too small to be used as food, so they are crushed to be made into either animal food or fertiliser. Fishing using nets is indiscriminate. Any fish which get in the way of the net will be caught in it if they are too big to get through the mesh. For every one tonne of prawns caught, three tonnes of other fish are killed and thrown…
Desjardins and Fernald (2010) wanted to discover whether fighting an opponent is similar to fighting a mirror image. These male fish are territorial and tend to engage in fighting when they encounter another size-matched male. Thus, Desjardins and Fernald (2010) measured differences in behavioral, hormonal and brain activity between the different conditions. They also measure the immediate early genes such as the egr-1 and c-fos in four brain regions: dorsomedial telencephalon (amygdala),…
I'm just a blue fish. I live in the living room of my owners house. I live in a small bowl with cool colorful rocks and a couple of plastic plants. Im sitting on top of a side table next to a picture of my favorite owner. She has brown hair and blue eyes. She's my favorite because she always gives me a little extra food when no one's watching. She also uses a fish net instead just dumping me while cleaning my bowl. Sometimes it gets a little boring being a fish. Most of the time I just swim…
communication by animals. Many fishes are capable of producing sounds with the help of specialized structures. Fish have evolved the largest diversity of sound-producing mechanisms among vertebrates, and sounds are emitted in numerous contexts: e.g. disturbance situations, during courtship, competitive feeding and territorial encounters. Sounds are also produced unintentionally including those made as a by-product of feeding or swimming. The majority of sounds produced by fishes are of low…
