Full artificial breeding method for Sanjiaofan clam and Chidie clam

Abstract

An artificial reproduction method for lateen mussel or butterfly mussel includes such steps as choosing more than 3 years old parents, temporarily culturing in adult mussel pool, injecting the chorionic gonadotropin in female parent, culturing the female parents in individual pool, taking the seminal fluid from male parent, diluting by sodium chloride solution, injecting it in female parent twice, culturing in temporary pool until glochidium is mature, parasitizing and culturing young mussel.

Description

technical field

[0001] The invention relates to artificial propagation of freshwater shellfish. Background technique

[0002] Triangle clam is a mollusc, belonging to the clambranchia, Euphyllobranches, clamidae, genus Sail, alias: trigonum clam, water shell, split clam, Jiangbei, wing clam, river clam, shovel clam, small shell Wait. It is an excellent freshwater pearl mussel unique to China, distributed in lakes and surrounding rivers in Hebei, Shandong, Anhui, Jiangsu, Zhejiang, Jiangxi, Hubei and Hunan provinces. In lakes such as Dongting Lake, Poyang Lake, Taihu Lake, Hongze Lake, Chaohu Lake, Shaobo Lake and Gaobao Lake and their surrounding rivers, the yield is relatively high. In China, the pearls produced by the triangular sail clam are of the best quality. The pearls are fine, smooth, bright in color and round in shape, but the production of pearls is relatively slow. At the same time, most of the parents used for breeding are wild species or long-term inbreeding....

Embodiment Construction

[0010] The present invention selects male and female individuals above three years old, with relatively large shells, complete and undamaged shells, smooth shell surfaces, wide trailing edges, fat and non-sick soft bodies, no damage to gill valves, and strong physiques as parents. ;Before the breeding season, the male and female parents are temporarily raised in the clam ponds with fresh water quality, sufficient dissolved oxygen, and rich bait organisms; in the breeding season, about 10 hours before artificial insemination, intramuscular injection of chorion stimulating Gonadal hormone (HCG) 1000 units, and move the female mussels into the holding pond (cement pond or earthen pond with independent water inlet and outlet) for temporary cultivation; cut the gonad skin of the male clam with a scalpel, use a straw to extend into the gonad from the incision, and suck out The semen was diluted 10 times with 0.4% sodium chloride exudate, and then instilled into the mantle cavity of t...
