Whitefish (fisheries term)
Whitefish or white fish is a
Atlantic freshwater fish
.
Whitefish live on or near the
seafloor, and can be contrasted with the oily or pelagic fish, which live away from the seafloor.[citation needed][dubious ] Whitefish do not have much oil in their tissue, and have flakier white or light-coloured flesh. Most of the oil found in their bodies is concentrated in the organs, e.g. cod liver oil
.
Whitefish can be divided into
).Whitefish is sometimes eaten straight but is often used reconstituted for
clipfish and traded as a world commodity.[1] It is commonly used as the fish in the classic British dish of fish and chips
.
Growth
The growth amidst whitefish species can be altered due to intraspecific competition. Fish populations such as Vendace and Roach share zooplankton for food which is crucial for young populations of whitefish. As this competition occurs, growth rate can be affected within multiple age groups or at an older age.[2]
