A fish company is a company which specializes in the processing of fish products. Fish that are processed by a fish company include cod, hake, haddock, tuna, herring, mackerel, salmon and pollock.
The United States, China, Peru and Chile have the highest number of fish companies specializing in fish processing. The Northwest Pacific Ocean is considered to be the most vital fishing zone in terms of volume caught and processed which results in the United States being regarded as the number one fish producing country.[citation needed]
In developing countries, the livelihood of over 500 million people depends on fish and seafood products.
