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 ...
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.
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.
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.
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 ...

It has a traditional shaking (oscillating) table design with a riffled deck. [1] It is one of several brands of wet tables used for the separation and concentration of heavy ore minerals which include the ...

Tropical wet forests are characterized by the complex, physical structure of the ecosystem. There are many layers of plant communities, though they are rarely visible from the ground. Shrubs and creepers fill the forest floor with saplings dispersed throughout. Large trees hold their full crowns in the canopy, prohibiting sunlight from plants ...
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 ...
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture, which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans, molluscs and so on, in natural or pseudo-natural environments.
