Embodiment 1
[0057] 1. Method
[0058] (1) Cultivation of mixed populations
[0059] Cultivation of the first-generation Zihaimo hybrid population: select scallop "Bohai Red" with no damage to the shell, plump shell, and a shell height of more than 6 cm, and a total of 1,000 Gulf of Mexico scallops with no damage to the shell, plump shell, and a shell height of more than 5 cm , placed in the Qishui Port, Leizhou, Zhanjiang, where the water temperature is 25°C and the bait is abundant, to promote ripening simultaneously; 200 scallops "Bohai Red" with mature gonads and 200 Gulf of Mexico scallops were selected from them, and the two parents were placed in 27 ℃ In a separate small pond with sand-filtered seawater, heat up the running water to stimulate the parents to discharge sperm, and then put an appropriate amount of mixed sperm into the nursery pond in advance. Finally, a mixed population including parental self-fertilized eggs and hybrid fertilized eggs is obtained, and the larvae are ...
