On May 18, Chen Dunlin from Changsha Town, Rudong County, said that he had 1 pond. Because of the proximity to the sea, the salinity of the water body is about 0.1%. He wants to breed mud loach. He does not know whether the water body meets the growing conditions of loach, and because of the pond In itself, it is to cultivate crab species. Can muddy and crab be mixed?
The reporter interviewed Professor Ling Feifei from the Fisheries Research Institute of Soochow University. Ling Feifei said that ponds with a salinity of about 0.1% in water can be bred in ponds, but they are not suitable for polyculture with dung beetles.
Some species of crabs are cultivated directly using crab seedlings (megalophthalmia), and some are cultivated using crab (bean crab). If it is a pond cultivated with crab seedlings, the early loach may ingest some crab seedlings, resulting in a decline in the yield of pond crabs. After the pond crab seedling grows in the later period, the culture density is too large, and the river crab is a crustacean. Loach can be damaged. So muddy crabs and crabs or crabs cannot be mixed.
