A method and an apparatus for taking out the viscera of a fish. A fish the head of which is cut off, is conveyed by conveying belts and the belly of the fish is incised with a cutting blade. The fish the belly of which has been incised, is caused to rise along a bone-supporting plate to make the position of the bone constant. The pointed end of a membrane peeling-off blade is inserted into the top portion outside a coelomic membrane of the fish to strip the coelomic membrane from the fish. Since the viscera of the fish is wrapped in the coelomic membrane the viscera is taken out from the fish meat by stripping the coelomic membrane from the fish meat.

Why it's free to use
- Filed February 8, 1994 and granted April 3, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 8, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 8, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
