If the fish in the fish pond has been poisoned by someone, it cannot be eaten. If it has been electrocuted, it can be eaten. If you are not sure about the situation, it is recommended not to eat it casually.

If the fish dies due to poisoning, it must not be eaten as it will be very harmful. If the fish dies due to lack of oxygen, it will not be edible even if it takes a long time to die.

Generally, fish, shrimps, and crabs that have been dead for more than 8 hours may be spoiled to varying degrees. After the fish dies, the surface, gills and intestines of the fish contain a certain amount of bacteria, and the dead fish is more likely to become a place for bacteria to multiply.

If the fish body is elastic and has no mucus, the time to death is shorter and it can be eaten. If the fish body is loose, soft, floating, and has mucus, it is basically certain that the dead fish has deteriorated. It is recommended not to eat.
