There are three stages in the artificial breeding of Hexi oysters, namely, the artificial propagation of the river otters, the breeding and management of the river oysters and the breeding of the oysters.
HeLa artificial propagation: First, select the mature female quail and the strong physique with the seedlings, generally 3 to 4 inches in length, such as flower buds, grass carp and other fish as seedlings. Artificial breeding of spiny bream can use stingray fingerlings. Breeding water requires lean water and adequate dissolved oxygen. When the young cricket grows to 0.5 centimeters, it is necessary to divide it. The waters grown by the small pheasants require depths of 60-80 cm. It is best to keep the water running slowly to prevent herring and squid and other food-eating fish from entering the waters.
The technology of cutting in river rafts: The river raft insertion is the most crucial technical measure in the process of breeding pearls. It requires the use of surgical gowns of the right age and must be maintained for a period of time to make them strong in physique; the surgical intervention must be meticulous and brisk. Choose the insertion site on the mantle membrane.
Feeding and management of bred pupa: The waters of raising pupa and breeding pearls should be selected to be sunny, no turfgrass, no pollution, fertile water, water flow, stable water level, ponds, lakes, ditches, reservoirs with water depths of 0.8-2.0 meters. Wait. In general, where fish can be raised, it is possible to raise the pearl. In the process of production management, it is necessary to constantly adjust the water quality and the depth of rigging in different water areas and in different seasons.
