>>945091OP here, you don't need a filleting knife, although it can help sometimes. Most fish just kill it, bleed it, then stab its bumhole and cut up through to the gills, rip out all the gross shit, rinse and you should be good to cook.
>>945174 filleting/removing stomach linings, etc are vital for alot of fish that I catch as they will ruin the taste>>945210 /b/ just called me and asked for you back, edgelord.
