Abstract
A method of processing fish fillets into seafood products is disclosed. Fish fillets can be readily and quickly processed into frozen seafood products having desired shapes. After catching fish and other fishery products, only fillets thereof that are suited for food are converted to frozen blocks aboard ship. The frozen blocks cut into pieces are pressure-formed into a desired shape after they are transported to a processing place on land.

- freezing the arranged fillets into a frozen block;
- cutting said frozen block into individual pieces and pressure-forming each of said pieces into an elongate shape, in which the fillets are bound in the frozen integrated state and said spaces between adjacent fillets are eliminated by said pressure-forming.
