ichthyootoxic fishes

ichthyootoxic fishes
those fishes that produce a poison that is generally restricted to the gonads of the fish; the musculature and other parts of the fish are usually edible. There is a definite relationship between gonadal activity and toxin production. These fishes are mainly freshwater, but a few marine species have been incriminated. The most dangerous forms are the genera Barbus, Schizothorax, Tinca (Cyprinidae) and Stichaeus (Stichaeidae)
