Embodiment 1
[0021] The first step is to collect parents of Philippine clams from different geographical groups: In 2005, 2-year-old healthy individuals were selected as parents. The parents were from Putian in southern China, Dalian in northern China, Busan in South Korea, and Tokyo in Japan.
[0022] The second step, the ecological maturation promotion of clam parents of different geographical groups: the collected parents were placed in the shrimp ponds of Zhuanghe Ocean Village for ecological maturation promotion. Mature in sync.
[0023] The third step, the binary positive and negative hybridization of the populations of North and South China, Korea and Japan: Use an electric drill with a diameter of 0.6mm to identify the gender of the parents. After identification; after being stimulated by drying in the shade for 8 hours and running water for 1 hour, the parents can simultaneously lay eggs and ejaculate; Then follow South China♀×North China , Northern China♀×Southern China ;Kore...
Embodiment 2
[0028] The first step is to collect parents of Philippine clams from different geographical groups: In 2005, 2-year-old healthy individuals were selected as parents. The parents were from Putian in southern China, Dalian in northern China, Busan in South Korea, and Tokyo in Japan.
[0029] The second step, ecological maturation promotion of clam parents of different geographical groups: the collected parents were placed in the tidal flats of Zhuanghe Ocean Village for ecological maturation promotion. After 6-12 months of bottom sowing breeding, the gonads were synchronized in the autumn of 2006 Mature.
[0030] The third step, the binary positive and negative hybridization of the populations of North and South China, Korea and Japan: Use an electric drill with a diameter of 0.6mm to identify the gender of the parents. After identification; after being stimulated by drying in the shade for 8 hours and running water for 1 hour, the parents can simultaneously lay eggs and ejaculat...
Embodiment 3
[0035] The first step is to collect parents of Philippine clams from different geographical groups: In 2005, 2-year-old healthy individuals were selected as parents. The parents were from Putian in southern China, Dalian in northern China, Busan in South Korea, and Tokyo in Japan.
[0036] The second step, the ecological maturation promotion of clam parents of different geographical groups: the collected parents were placed in the shrimp ponds of Zhuanghe Ocean Village for ecological maturation promotion. Mature in sync.
[0037] The third step is the binary positive and negative hybridization of the populations of North and South China, Korea and Japan: through the stimulation of 8 hours of shade drying and 1 hour of running water, the parents can simultaneously lay eggs and ovulate; during the process of ovulation and ovulation, male and female can be distinguished, and the The male and female individuals were captured separately; and then according to South China ♀×North Ch...
