Problems solved by technology

In recent years, the coastal areas of Fujian, Jiangsu, Zhejiang, Hebei and other provinces have begun to artificially breed chrysanthemum yellow puffer. However, due to the long breeding cycle, it takes 3 years to reach the commercial fish size (weight greater than 300g), and the cost of

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

Example Embodiment

[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 );

Abstract

The invention discloses a method of shortening the cultural period of the Takifugu flavidus, which includes the following steps: (1) selecting the Takifugu flavidus and the Takifugu rubripes at age between 3 and 5 in proportion of 2 to 1 in every March and April for parent fish induced mature culturing; (2) induced breeding and artificial egg collecting by using Luteinizing Releasing Hormone Analog (LRH-A); (3) artificial inseminating the Takifugu flavidus ovum with the Takifugu rubripes sperm; (4) fish fry culturing; (5) culturing in the outdoor earth pond when the body length of the fish fry is more than 3 cm; (6) culturing the fish fries in the fish fry room through the winter; (7) moving the overwintering fish to the outdoor fishpond when the outdoor water temperature is at more than 12 DEG C and going on the market after about five months' culture. The experimental culture result of the method shows that the average weight of the fish reaches more than 0.35 kg, wherein the maximum weight is 0.7 kg; the cultural period is shortened more than one time. The method reduces the culture cost by a big margin and greatly increases the Takifugu flavidus fish product culture benefit.

Description

technical field [0001] The invention relates to a method for shortening the culturing period of commercial fish of puffer chrysanthemum and belongs to the technical field of aquatic biological genetics and breeding. Background technique [0002] Takifugu flavidus belongs to the Fuguformes, Fuguidae. It is mainly distributed in the East China Sea, the Yellow Sea and the Bohai Sea in my country. It is a temperate offshore fish, and the adult fish generally have a body length of 150-250mm. The chrysanthemum yellow oriental puffer is delicious and nutritious, and it is a good product on the table in Jiangsu and Zhejiang in my country. In recent years, the coastal areas of Fujian, Jiangsu, Zhejiang, Hebei and other provinces have begun to artificially breed chrysanthemum yellow puffer. However, due to the long breeding cycle, it takes 3 years to reach the commercial fish size (weight greater than 300g), and the cost of breeding is high and the benefits are high. Low, which limi...
