The term fish processing refers to the processes associated with fish and fish products between the time fish are caught or harvested, and the time the final product is delivered to the customer. Although the term refers specifically to fish, in practice it is extended to cover any aquatic organisms harvested for commercial purposes, whether ...
A fish fillet processor processes fish into a fillet. Fish processing starts from the time the fish is caught. Popular species processed include cod, hake, haddock, tuna, herring, mackerel, salmon and pollock. Commercial fish processing is a global practice. Processing varies regionally in productivity, type of operation, yield and regulation
"Multi-trophic" means that the various species occupy different trophic levels, i.e., different (but adjacent) links in the food chain. [ 2 ] IMTA is a specialized form of the age-old practice of aquatic polyculture , which was the co-culture of various species, often without regard to trophic level.
Fish and other aquatic organisms are also processed into various food and non-food products. Live, fresh or chilled is often the most preferred and highly priced form of fish and represents the largest share of fish for direct human consumption, 45 percent in 2016, followed by frozen (31 percent), prepared and preserved (12 percent) and cured ...
An integrated aquaculture system consists of a number of species at different trophic levels of the food chain. Thus waste generating (fed organisms) such as fish and shrimp are coupled with extractive organisms such as abalone, sponges or sea urchins, as a mechanism of removing excess nutrient matter from the water column.
A fish factory, also known as a fish plant or fish processing facility, is a facility in which fish processing is performed. They are commonly located near bodies of water but can be located inland and on fishing vessels. The availability and variety of fish influences the scale of fish factories and the processing methods they utilize.
A relatively new concept is relationship farming. This is a way of operating farms so they restore the food chain in their area. Re-establishing a healthy food chain can result in the farm automatically filtering out impurities from feed water and air, feeding its own food chain, and additionally producing high net yields for harvesting.
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
