Do crayfish have parasites
Crayfish have a very complex diet. In addition to plant straw and water grass, they also eat dead fish or similar corpses. Because of their habit of eating rotten corpses, their bodies carry a lot of bacteria and toxic substances. In order to earn money, some traders organized manpower to catch crayfish growing in the wild environment in rivers and mud ponds, which were transported to the market without quarantine and sold at a low price. After many crayfish died, they became a hotbed for bacteria to multiply in large quantities.
There are some disadvantages in artificial culture. In order to cater to the growth habits of crayfish and shorten the growth cycle, some traders deliberately feed unclean feed to the pond; what's more, they take the polluted pond and mud as the breeding ground, and if the crayfish growing in the environment is placed on the table, it will pose a serious threat to human health.
According to people familiar with the matter, the waters where crayfish live are full of plankton. Whether cultured or wild, they are the hosts of parasites. This species is also used to absorb heavy metals and toxic substances in water in some countries.
