Claims10
A method of filleting fish comprising the steps of making a pair of initial longitudinal cuts into the fish one on each side of, closely adjacent, and parallel to the vertebral column of the fish to be filleted, which cuts pass down through the skin towards but not into the parapophyses, accommodating ploughs in each of said initial cuts, and by relative movement between the ploughs and the fish, drawing a side fillet clear of the rib and pin bones and main bone structure on each side of the fish.
An apparatus for filleting fish comprising a carrier saddle to carry the fish in the machine, a pair of cutter knives located to make initial longitudinal cuts one on each side of, closely adjacent, and parallel to the vertebral column of a fish located on said carrier saddle, and a pair of ploughs each located and arranged to enter into one of said cuts during movement of the carrier relative to said ploughs and then to draw a side fillet clear of the rib and pin bones and main bone structure of the fish on the said carrier.
