Example Embodiment
[0023] Example 1
[0024] Location: Hebei Fisheries Research Institute Redfin Oriental Puffer Breeding Farm
[0025] This embodiment takes the following steps:
[0026] (1) Choose to breed broodstock
[0027] On March 15, 2006, 10 3-4 years old chrysanthemum puffer and 5 red fin male puffer were selected;
[0028] (2) Broodstock promotes maturity cultivation and induces labor
[0029] The broodstock of chrysanthemum puffer and redfin puffer fish were cultured in separate ponds, the water temperature was controlled at 18±1℃, the water was changed 1 / 3-1 / 2 every day, and the silkworm was fed once at 8% of the body weight of the broodstock. After 30 days, After cultivating, on April 15 according to the injection amount to compare the body weight of the broodstock: 100mg / kg and 50mg / kg respectively inject the luteinizing-releasing hormone analog (LRH-A) into the chrysanthemum and redfin puffer;
[0030] (3) Artificial insemination and hatching

[0040] Example 2
[0041] Location: Haiyong Farm, Changli County, Hebei Province
[0042] This embodiment takes the following steps:
[0043] (1) Choose to breed broodstock
[0044] On March 10, 2006, 30 3-4 years old chrysanthemum fugu and 15 redfin males were selected;
[0045] (2) Broodstock promotes maturity cultivation and induces labor
[0046] The broodstock of chrysanthemum puffer and redfin puffer were cultured in separate ponds, the water temperature was controlled at 18±1℃, the water was changed 1 / 3-1 / 2 every day, and the sand silkworms were fed once, and the feeding amount was calculated as 8% of the body weight of the broodstock After more than 30 days of maturation promotion and cultivation, on April 20, the injection volume was compared with the body weight of the broodstock: 100mg / kg and 50mg / kg, respectively, to inject luteinizing-releasing hormone analogs (LRH-A );
[0047] (3) Artificial insemination and hatching
[0048] 72 hours after the injection of the oxyt...
