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....

AI Technical Summary

Problems solved by technology

[0007] The present invention needs to solve the problem that the source of the male sperm cannot be known for sure in the semi-artificial reproduction of the current production of the triangular sail mussel and the chrysalis, the hybridization is easily affected by the impurity, and the artificial breeding time cannot be accurately controlled
