Embodiment 1

[0016] The production method of the pearl clam new strain with strong secretion ability comprises the following steps:

[0017] The production method of the pearl clam new strain with strong secretion ability comprises the following steps:

[0018] (1) Selection of parents: choose a healthy and healthy Hypophyllus mussel as the female parent, with large individuals, complete and undamaged shells, smooth shell surface color, wide trailing edge, fat and non-sick soft body, no damage to gill flaps, and strong physique. As the male parent of the clam, the male and female parents are separated and raised 6-12 months before the hybridization;

[0019] (2) Treatment of the parents: Put the parent of the Hypophyllus sinensis selected in the step (1) into the breeding pond of the Hypochondria coliformis parent, and feed yeast and an appropriate amount of organic fertilizer. The amount of fertilizer input is 3-5kg / m³ cultured water body, and the water temperature of the cultivation poo...

Embodiment 2

[0023] The production method of the pearl clam new strain with strong secretion ability comprises the following steps:

[0024] (1) Selection of parents: choose a healthy and healthy Hypophyllus mussel as the female parent, with large individuals, complete and undamaged shells, smooth shell surface color, wide trailing edge, fat and non-sick soft body, no damage to gill flaps, and strong physique. As the male parent of the clam, the male and female of the parents were separated and raised 12 months before the hybridization;

[0025] (2) Treatment of the parents: put the parent of the Hypophyllus sinensis selected in the step (1) into the breeding pond of the Hypochondriophyllum parent, and feed yeast and an appropriate amount of organic fertilizer. Control the water temperature of the breeding pool at 20°C; put the parent clam in the breeding pool of the parent clam, and feed artificially cultivated cryptoalgae, diatoms, and green algae, so that the algae content in the water ...

Abstract

The invention discloses a production method of new lines of a pearl mussel with high secretion ability. The method comprises the steps of parent selection, parent processing, artificial insemination, incubation and the like. According to the production method, the difficult problems of hybridization aspects of hyriopsis cumingii and lamprotula leai are solved; through breeding tests, the hybridization F1 generation has the advantages of high pearl producing speed, high disease resistance, high oxygen deprivation tolerance ability and the like, can be widely applied to large-scale production of freshwater pearl and shell industry, and has better production and application values.

Description

technical field [0001] The invention relates to the technical field of breeding of new strains of pearl-growing mussels in freshwater, in particular to a production method of new strains of pearl-growing mussels with strong secretion ability. Background technique [0002] Generally, freshwater mussels can form pearl mussels, but some mussels may produce pearls not ideal due to poor pearl secretion ability. In actual production, there are only more than 10 species of mussels that can be used to cultivate pearls. At present, domestic and foreign production The most widely used pearl mussels in the world have only a few varieties such as triangular sail mussels, pleated crown mussels, pond butterfly mussels, and mother-of-pearl pearl mussels. my country's pearl production is mainly the first two. [0003] Triangle sail clam, the shell surface is large and flat, the shell is hard and thick, the double shell is relatively flat, the nacre is smooth and dense, and it belongs to the ...
