It contrasts round fish with flatfish, explains pin bones, tables fillet yields, which it puts at 55 to 60% for rainbow trout, and follows the enzymes and bacteria that soften flesh and build up biogenic amines. The species are mostly marine and commercial, from salmon and cod to halibut and sole, and it gives Pacific cod the Latin name Gadus morhua, which belongs to the Atlantic cod, a sign that details need checking.
