Embodiment 1
[0020] Select 20,000 wild oysters from the Yellow Sea.
[0021] A seed production method of a new strain of black-shell long oyster, comprising the following steps:
[0022] a. Initial screening: From the wild long oyster population, initially screened out that both shells are black, and the mantle is black, the meat yield is high, and the group with regular shell shape is 2000 as the core group;
[0023] b. Secondary selection: take the core population of black-shelled long oysters selected in step a as the basic group, and use the truncation selection method to optimize 10% of the population's internal shells with black shells, high meat yield, and long oysters with black mantles 200 individuals as the preferred group;
[0024] c. Self-propagation of the superior group: take the optimal group in the b step as the breeding group, carry out offspring cultivation according to the conventional shellfish seedling raising method, and obtain the new black shell strain F 1 ;

Embodiment 2
[0028] Select 10,000 wild oysters from the Bohai Sea.
[0029] A seed production method of a new strain of black-shell long oyster, comprising the following steps:
[0030]a. Initial screening: From the wild long oyster population, initially screened out that both shells are black, and the mantle is black, the meat yield is high, and the group with regular shell shape is 1200 as the core group;
[0031] b. Secondary selection: take the core population of black-shelled long oysters selected in step a as the basic group, and use the truncation selection method to optimize 10% of the population's internal shells with black shells, high meat yield, and long oysters with black mantles 120 individuals as the preferred group;
[0032] c. Self-propagation of the superior group: take the optimal group in the b step as the breeding group, carry out offspring cultivation according to the conventional shellfish seedling raising method, and obtain the new black shell strain F 1 ;

Embodiment 3
[0037] The new strains of black-shelled oysters obtained in Examples 1 and 2 were normally bred. After 10 months of age, some indicators were measured and compared with 10-month-old common oyster varieties, and some were bred normally.
[0038] 1. Shell height: randomly select 50 new strains of black-shelled long oysters obtained from seed production in Examples 1 and 2 of 10 months of age respectively, randomly select 50 common 10 months of long oyster varieties, measure and record, and use the result Can get, the long oyster shell height of embodiment 1 and 2 black-shell long oyster new strains is 10.6% higher than common long oyster on average.
[0039] 2. Body weight: same as above, carry out overall weight measurement, can get from the result, the overall weight of the long oyster of embodiment 1 and 2 black-shell long oyster new strains is 15.3% higher on average than common long oyster.
[0040] 3. Meat yield: the same as above, focus on taking out the soft oysters. Fro...
