Can you still eat black fish when they are dead?

It's best not to eat blackfish when they're dead, unless they just died. Because black fish is carnivorous fish, once dead, a large number of bacteria will grow in the body, if eaten will lead to physical discomfort, so it is best not to eat. Generally can break open the fish Gill to see whether the cheek is white, if white means that it has been dead for a long time, not suitable for consumption.

Which fish are dead and can't be eaten?

Dead eels and soft-shelled turtles are not edible. Because the eel contains more histamine acid and trimethylamine oxide. After death, its histamine acid can be decomposed into toxic histamine under the action of decarboxylase and bacteria. Adults can be poisoned by taking 100 milligrams at a time. Its trimethylamine oxide can be reduced to trimethylamine, aggravating its fishy smell. Polyhistamine acids in dead soft-shelled turtles can be decomposed into highly toxic histamines and histamines. Someone sprayed the eel in the field with "bromogerin" to catch the eel after it was poisoned, which added a new source of foreign poison to the eel.

The above is the introduction of how to eat blackfish when it is dead. I hope it will be helpful to everyone.
