Sturgeons are not poisonous when they die within 6 hours, because they are not poisonous fish themselves, and they are nontoxic even after they die. However, when sturgeons die for more than 6 hours, histamine in their bodies will be decomposed into histamine, and with the increase of sturgeon death time, the decomposition rate of histamine will also accelerate. When sturgeon dies for too long, there will be more and more histamine in the body. At this time, if you eat it, it is easy to cause poisoning.

In addition, try not to eat sturgeon that died naturally in the wild, because the pollution is serious now, and sturgeon is likely to die due to pollution. Contaminated sturgeon will leave some harmful substances in its body, which may lead to food poisoning after eating. And now wild sturgeon are protected animals, so try not to eat them.

There are many species of sturgeon, and different species are distributed in different sea areas. Some sturgeons live in seawater, and some sturgeons live in fresh water, so it is impossible to say in general whether they are marine fish or freshwater fish. In addition, some sturgeons have migratory habits. Like Chinese sturgeon, it is mainly distributed in the Yangtze River basin. But when they grow, they will enter the sea, and when they are old enough to breed, they will return to the Yangtze River.
