1, breeding methods

(1)Pond culture area should be adapted to local conditions, small pond for 3-5 mu, large pond from more than ten mu to dozens of mu, water quality is generally more fertile, bait organisms rich, pond can be mixed culture grass carp, bream, crucian carp, not suitable for breeding competitive fish such as silver carp, etc., do not stock carnivorous fish such as herring, snakehead, etc.

(2)To choose a pollution-free river, sufficient oxygen, fresh water quality, water flow state, sufficient material exchange, suitable for the growth of Hyriopsis cumingii.

(3)If lakes, reservoirs, etc. are selected, the water area should be larger, and the shallow water area on the shore or bend should be selected for pearl mussel cultivation. The water body fluidity should be good, the water quality should be clear, and the dissolved oxygen should be rich.

2. Precautions

(1)Pearl mussel culture should pay attention to these three points: water quality environment, mussel culture technology, for fish pearl polyculture variety selection.

(2)Pearl mussels in the breeding, can be mixed in the breeding pond fish, such as crucian carp, silver carp, yellow spicy Ding and other fish species, but can not be mixed catfish, mullet and other ferocious fish.

(3)In the mixed culture of fish, do not mix fish with diseased pearl mussels, otherwise it will lead to the death of pearl mussels and fish. If diseased pearl mussels occur, medication should be given in time.
