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 ...
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.
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.
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.
Canned or tinned fish are food fish which have been processed, sealed in an airtight container such as a sealed tin can, and subjected to heat. Canning is a method of preserving food, and provides a typical shelf life ranging from one to five years.
Bacteria, yeasts and molds need the water in the food to grow, and drying effectively prevents them from surviving in the food. Fish are preserved through such traditional methods as drying, smoking and salting. The oldest traditional way of preserving fish was to let the wind and sun dry it.
Aquaculture can be conducted in completely artificial facilities built on land (onshore aquaculture), as in the case of fish tank, ponds, aquaponics or raceways, where the living conditions rely on human control such as water quality (oxygen), feed, temperature.
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.
As opposed to dry salting, fish brining or wet-salting is performed by immersion of fish into brine, or just sprinkling it with salt without draining the moisture. To ensure long-term preservation, the solution has to contain at least 20% of salt, a process called "heavy salting" in fisheries; heavy-salted fish must be desalted in cold water or ...
In a typical recirculating aquaculture system, a series of filtration steps maintains a high level of water quality that promotes rapid fish growth. Steps include solids removal, biofiltration, oxygenation, and pumping, with each one requiring different equipment and engineering considerations.
