A medieval view of fish processing, by Peter Brueghel the Elder (1556). There is evidence humans have been processing fish since the early Holocene. For example, fishbones (c. 8140–7550 BP, uncalibrated) at Atlit-Yam, a submerged Neolithic site off Israel, have been analysed. What emerged was a picture of "a pile of fish gutted and processed ...
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.
Fermentation is a method which attacks the ability of microbials to spoil fish. It does this by making the fish muscle more acidic; bacteria usually cease multiplying when the pH drops below 4.5. A modern approach, biopreservation, adds lactic acid bacteria to the fish to be fermented.
In Europe, brown trout are the most commonly reared fish for recreational restocking. [4] Commonly farmed non-salmonid fish groups include tilapia, catfish, black sea bass and bream. In 2007, the aquaculture of salmonids was worth USD $10.7 billion globally. Salmonid aquaculture production grew over ten-fold during the 25 years from 1982 to 2007.
Fish preservation is the method of increasing the shelf life of fish and other fish products by applying the principles of different branches of science in order to keep the fish, after it has landed, in a condition wholesome and fit for human consumption. [1][2] Ancient methods of preserving fish included drying, salting, pickling and smoking.
The 2008 global returns for fish farming recorded by the FAO totaled 33.8 million tonnes worth about US$60 billion. [6] Although fish farming for food is the most widespread, another major fish farming industry provides living fish for the aquarium trade. The vast majority of freshwater fish in the aquarium trade originate from farms in Eastern ...
Canning is a method of food preservation in which food is processed and sealed in an airtight container (jars like Mason jars, and steel and tin cans). Canning provides a shelf life that typically ranges from one to five years, [a] although under specific circumstances, it can be much longer. [2] A freeze-dried canned product, such as canned ...
Commercial fish feed. A betta fish eating commercial fish food. Manufactured feeds are an important part of modern commercial aquaculture. They provide the balanced nutrition needed by farmed fish. The feeds, in the form of granules or pellets, give nutrition in a stable and concentrated form, enabling the fish to feed efficiently and grow to ...
