You cannot eat the dead sturgeon.

The scientific name of the sturgeon, Blue Crab, is a type of crab. When a crab is dying or dead, the histoxic acid in the crab's body will decompose to produce histamine. Histamine is a toxic substance. As the death time prolongs, more and more histamine accumulates in the crab body, and the poisonous gas becomes stronger and stronger. Even if the crab is cooked, this toxin is not easily destroyed. Therefore dead crabs are inedible. Extended information

To buy fresh river crabs, you should do "five things" when choosing crabs: first, look at the color; second, look at the individual; third, look at the belly button; fourth, look at the crab hair; fifth, look at the movement. The color of the crab should be green back and white belly; golden claws and yellow hair; the crab should be large and old and healthy; the navel should protrude outward; the crab legs should be covered with hair; the movements should be agile and active. Only those that meet these 5 criteria are the best to buy.
