Problems solved by technology

Foreign research reports have confirmed that in the Mediterranean Sea, the North Sea, the English Channel, and the west coast of the United States, there are also hybridization phenomena of mussel species such as blue mussels, Mediterranean mussels, and Geller mussels, and the physiological effects of interspecific hybrid offspring of mussels The characteristics have been explored, but so far there is no relevant report on the use of interspecific hybridization for productive seedlings at home and abroad

Embodiment 1

[0033] Select 20Kg of wild thick-shelled mussels from Shengsi County, Zhejiang and 10Kg of blue mussels cultured in Dalian sea area of ​​Liaoning as parents. L's KMNO 4 The solution was bathed for 10 minutes, and the parent scallops were put into the pool for intensive cultivation for 15 days; among them, the parent scallops were intensively cultured under the following conditions: the parent scallops were kept at a volume of 3.0kg to 4.5kg / m2. 2 , keep the water temperature at 12°C, water depth of 50cm, change the water 200% a day, and change the water twice a day; cast flat algae (density 30,000 / ml) and Zhanjiang Isochrysis algae (density 80,000 / ml) as bait; After the shellfish gonads reached full maturity, the parent shellfish was disinfected again, placed in a dry and ventilated place to dry in the shade for 18 hours, stimulated by running water for 1.5 hours, and the water flow intensity was 40t / h; ) collecting eggs in still water, observe the oviposition and ovulation s...

Embodiment 2

[0035] Select 20Kg of wild thick-shelled mussels from Shengsi County, Zhejiang and 10Kg of blue mussels cultured in Dalian sea area of ​​Liaoning as parents. L's KMNO 4 The solution medicated bath for 10min, put the parent shellfish into the pool for intensive cultivation for 10 days; the parent shellfish enhanced culture conditions are: the parent shellfish storage amount is 3.0kg ~ 4.5kg / m 2 , keep the water temperature at 15°C, water depth of 50cm, change the water 300% a day, and change the water 3 times a day; cast flat algae (density 20,000 / ml) and Zhanjiang Isochrysis (density 100,000 / ml) as bait; After the shellfish gonads reached full maturity, the parent shellfish were disinfected again, placed in a dry and ventilated place to dry in the shade for 18 hours, stimulated by running water for 2 hours, and the water flow intensity was 35t / h; they were placed in the egg collection pond for seedling collection net curtains (made of 60 mesh silk) The eggs were collected in ...

Embodiment 3

[0037] Select 20Kg of wild thick-shelled mussels from Shengsi County, Zhejiang and 10Kg of blue mussels cultured in Dalian sea area of ​​Liaoning as parents. L's KMNO 4 The solution was bathed for 8 minutes, and the parent shellfish was put into the pool for intensive cultivation for 7 days; among which the parent shellfish enhanced culture conditions were: the parent shellfish stocking amount was 3.0kg-4.5kg / m 2, keep the water temperature at 16°C, water depth of 50cm, change the water 100% a day, and change the water once a day. After the shellfish gonads reached full maturity, the parent shellfish were disinfected again, placed in a dry and ventilated place to dry in the shade for 16 hours, stimulated by running water for 3 hours, and the water flow intensity was 30t / h; respectively, put them into the egg collection pond for seedling collection net curtains (made of 60 mesh silk screen) The eggs were collected in still water, and the egg laying and ovulation of the parent ...

Abstract

The invention relates to an artificial seedling method for hybrid mussels in factory, comprising the seedling steps as follows: parent clam selecting, parent clam reinforced cultivation, stimulating the production by drying in the shade and flowing water, selecting the spermatozoa of the male parent thick shell mussels and ovum of the female parent blue mussel, larval culture, juvenile culture, etc. The hybrid seedling technique of the invention can successfully cultivate the healthy and high-quality hybrid juvenile mussels, provide the material condition for the property improvement of the mussels, meanwhile, the method of the invention lays the technical foundation for adding a new cultivation type for the seawater mussel cultivation in China and has important theoretical significance and wide application prospect.

Description

technical field [0001] The invention relates to a method for raising seedlings of mussels, in particular to an artificial seedling raising method for industrialized hybrid mussels, and belongs to the technical field of aquaculture. Background technique [0002] Heterosis is a ubiquitous and important biological phenomenon, which plays an important role in improving the production performance of organisms. As an important way of breeding aquatic organisms, hybrid breeding has played a role in the improvement and production of aquatic organisms. Variability and heterogeneity, synthesizing the excellent traits of the parents, producing new traits that some parents do not have, and the emergence of available heterosis and other positive factors. Thus, heterosis will be the genetic basis for modern shellfish breeding. In order to solve the problems of large-scale death of cultured shellfish in my country and slow growth and long production cycle of some important economic shellf...
