Fish physiology. When threatened, the toxic pufferfish fills its extremely elastic stomach with water. [1] Fish physiology is the scientific study of how the component parts of fish function together in the living fish. [2] It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes.
Tilapia, often farmed, is a popular and common supermarket fish in the United States. [citation needed] In India, Nile tilapia is the most dominant fish in some of the South Indian reservoirs and available throughout the year. O. niloticus grows faster and reaches bigger sizes in a given time. The littoral areas of Kelavarappalli Reservoir are ...
Population dynamics describes the ways in which a given population grows and shrinks over time, as controlled by birth, death, and migration. It is the basis for understanding changing fishery patterns and issues such as habitat destruction, predation and optimal harvesting rates. The population dynamics of fisheries is used by fisheries ...
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish (but not cartilaginous fish) to control their buoyancy, and thus to stay at their current water depth without having to expend energy in swimming.
The fish are often "conditioned" (starved) before they are transported to reduce their metabolism and increase packing density, and the water can be cooled to further reduce metabolism. Live crustaceans can be packed in wet sawdust to keep the air humid. By air: Over five percent of the global fish production is transported by air.
Physostomes are fishes that have a pneumatic duct connecting the gas bladder to the alimentary canal. This allows the gas bladder to be filled or emptied via the mouth. This not only allows the fish to fill their bladder by gulping air, but also to rapidly ascend in the water without the bladder expanding to bursting point.
A fish fillet, from the French word filet (pronounced) meaning a thread or strip, is the flesh of a fish which has been cut or sliced away from the bone by cutting lengthwise along one side of the fish parallel to the backbone. In preparation for filleting, any scales on the fish should be removed. The contents of the stomach also need careful ...
A fish can have up to three dorsal fins. The dorsal fins serve to protect the fish against rolling, and assist it in sudden turns and stops. The bones that support the dorsal fin are called pterygiophores. There are two to three of them: "proximal" (axonosts), "middle" (baseosts), and "distal".
Taiyaki (鯛焼き, lit.'baked sea bream ') is a Japanese fish -shaped cake, commonly sold as street food. It imitates the shape of tai (鯛, red sea bream), which it is named after. [1] The most common filling is red bean paste that is made from sweetened adzuki beans.
Water table. Cross-section of a hillslope depicting the vadose zone, capillary fringe, water table, and the phreatic or saturated zone. (Source: United States Geological Survey .) The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with groundwater ...
