Fish fillet processor Fish fillet processor 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. Approximately 90% of processed fish are oceanic fish. The remaining 10% are from commercial freshwater operations and aquacultural production. Most fish processing industries are near commercial fishing zones. In certain regions, fish are transported or exported for processing. The largest fish processing countries in order are: These
Environmental issues with salmon 59 years of catch and escapement data of Bristol Bay sockeye to determine age and size at maturity trends attributable to the selectivity of commercial gillnet harvests. The study found that the larger females (>550 mm) of all age classes were most susceptible to harvest. The study suggests that smaller, younger fish were more likely to successfully traverse the gillnet fishery and reproduce than the larger fish. The study also found that the average length of sockeye harvested from 1946–2005 was 8 mm larger than the sockeye who escaped the gillnet fishery to spawn, reducing the fecundity of the average
