Embodiment 1

[0033] Embodiment 1, a method for cultivating pond snakehead seedlings, comprising the following steps: selecting pond snakehead parents→proportional male and female pairing→intensive cultivation→disease prevention and treatment→propagation→seed cultivation;

[0034] Take the parent of Channa channa as an example:

[0035]Select the parent species of Channa mongolica, 30 days before the reproductive period of Channa mongolica, select the species of Channa mongolica with mature glands, strong body, no disease, healthy limbs, two or more years of reproductive age. Proportional male and female mating: according to the 1:3 ratio of male and female, the sand pond snakeheads are put into the sterilized spawning pond. Intensive cultivation: After pairing, the parents of the sand pond snakehead are fed with the breeding nutrient feed once in the morning and in the evening, and fed for 15 days. Disease prevention and control: After pairing, the broodstock of Snakeheads are disinfected...

Embodiment 2

[0037] Embodiment 2, a method for raising seedlings of snakeheads, comprising the following steps: selecting parents of snakeheads → pairing males and females in proportion → strengthening cultivation → disease prevention and control → breeding → seedling cultivation;

[0038] Take the parent of Channa channa as an example:

[0039] Select the parent species of Channa mongolica, 20 days before the reproductive period of Channa mongolica, select the species of Channa mongolica with mature glands, strong body, no disease, sound limbs, two or more years of reproductive age. Proportional male and female mating: according to the 1:3 ratio of male and female, the sand pond snakeheads are put into the sterilized spawning pond. Intensive cultivation: After pairing, the parents of the sand pond snakehead are fed with breeding nutrient feed once in the morning and in the evening, and fed for 18 days. Disease prevention and control: After pairing, the broodstock of Channa chinensis is d...

Embodiment 3

[0041] Example 3, such as figure 1 Shown, a kind of nursery pool body system of pond snakehead nursery, is characterized in that: comprise at least two or more than two water purification ponds 1, at least two or more spawning ponds 2, and at least two Two or more seedling ponds 3, the purification pond 1 is provided with water inlet pipeline 4 butt joint spawning pond 2, seedling pond 3, the bottoms of the spawning pond 2, seedling pond 3 are respectively provided with drainage pipes The road 5 communicates with a sewage treatment pond 6, and a pond snakehead seedling occupying and raising device is provided in the described nursery pond 3.

[0042] Such as figure 2 , as shown, further, the described pond snakehead seedling occupation and cultivation device includes a base 7 that can be sunk in water, and a plurality of telescopic rods 8 are set on the base 7, and a seedling retention plate 9 is installed on the upper end of the telescopic rod 8 to connect and tilt. A plur...

Abstract

The invention discloses an Eleotris acanthopoma fry breeding method and an Eleotris acanthopoma fry breeding pond body system. The method comprises the following steps of: selecting Eleotris acanthopoma parents, pairing the parents according to the ratio of females to males, breeding doughtily, preventing and controlling diseases, reproducing and breeding fries. The Eleotris acanthopoma fry breeding pond body system comprises a water purification pond, a spawning pond, a fry breeding pond and an Eleotris acanthopoma fry temporary culture device which is arranged in the fry breeding pond. By creating natural conditions and all kinds of condition factors during the reproduction of Eleotris acanthopoma to breed before the reproduction, the rate of fry emergence of sperms and follicle of Eleotris acanthopoma is improved and the survival rate of fertilized eggs is further improved. Moreover, by taking disinfection measures in all environments, the morbidity of the fries is reduced. The arranged simple Eleotris acanthopoma fry temporary culture device can be used for the hatching of the fertilized eggs and the culture of the fries at the same time. The space occupied for culture and the cost are reduced. The Eleotris acanthopoma fry breeding method and the Eleotris acanthopoma fry breeding pond body system are suitable for low-cost culture.

Description

technical field [0001] The invention relates to a seedling raising method, in particular to a pond snakehead seedling raising method and a pond snakehead seedling raising pond system. Background technique [0002] At present, there are about 16 genera and 30 species of fish in the family Channaidae. Distributed along the coast and in the middle and lower reaches of major rivers. The common genera are Wutang Channa, Pond Channa, Shatang Channa, Saw Pond Channa, Meitang Channa, Perch Pond Channa and so on. Channaidae are small edible fishes. Some species have tender and delicious meat. For example, Chinese snakeheads are produced in the South China Sea and the Taiwan Strait. They have high nutritional value and are valuable tonics. Jiantoutang snakehead fish is produced in China's Minjiang River, Pearl River and Taiwan. Shatang snakehead fish is produced in the Yangtze River, Pearl River, Qiantang River, Minjiang River and Taiwan to Northeast China. [0003] With the evolu...
