Problems solved by technology

[0005] Yet, there is following problem in above-mentioned cultivation method: (1) all will take a large amount of cement ponds because loach broodstock spawns to fish fry parallel swimming is carried out in cement pool, therefore every batch of loach is cultivated; And, from broodstock It takes an average of 5 days from spawning to loach seedlings swimming, that is, every batch of broodstock spawned will occupy the hatching facility for at

Embodiment 1

[0025] A method for hatching and cultivating loach, comprising the steps of:

[0026] (1) Pond preparation: Disinfect 1 cement pond, use 4 cultivation ponds as hatching ponds for cleaning pond disinfection, and use 1 cultivation pond as a fertilizer pond for cleaning pond disinfection and fertilizer water; that is, use 1 cement pond and 5 cultivation ponds. A cultivation pond is used as a linkage operation group; the water depth of the fertilizer water pond is about 100 cm, and the pond is disinfected with bleach powder 7 to 10 days before artificial induction, and the organic fertilizer that has been decomposed and fermented is applied to fertilize the water, and the dosage is 150 kg per 667 square meters; The water depth of the hatching pond is 20 cm, and the pond is disinfected with bleach powder 4 days before artificial induction, and no fertilizer is used;

[0027] (2) put broodstock in the cement pond behind above-mentioned clear pond, lay eggs;

[0028] (3) Put part of...

Abstract

The invention discloses a method for incubating oriental weatherfish, which includes steps: firstly, preparing cement ponds and culture ponds, using at least one cement pond as a spawning pond to be disinfected, using at least two culture ponds as incubating ponds to be disinfected, and using at least one culture pond as water fertilizing pond to be fertilized with water; secondly putting parent fishes into the disinfected cement ponds for the parent fishes to lay eggs; thirdly, putting fertilized eggs obtained in the step 2 into the incubating ponds mentioned in the step 1; fourthly, when young fishes start swim 4-5 days after incubation, using bolting silk to filter the water in the water fertilizing ponds mentioned in the step 1 and adding the water into the incubating ponds, and transferring the young fishes in the cement ponds into the water fertilizing ponds; and fifthly, conventionally incubating the young fishes in all of the incubating ponds and the water fertilizing ponds, and breeding the fishes by the conventional method. The method for incubating oriental weatherfish reduces use of the cement ponds and solves the problem of undersupply of incubating facilities, and bythe method, incubating survival rate is up to 50%, and the results are unexpected.

Description

technical field [0001] The invention relates to a method for hatching and cultivating fish, in particular to a method for hatching and cultivating loach, which realizes the hatching of loach and the cultivation of summer flower fish species. Background technique [0002] Loach is known as "ginseng in water" for its delicious taste, tender meat and rich nutrition. According to analysis, every 100 grams of loach meat contains 18.4 grams of protein, 2.9 grams of fat, and the content of vitamin B1, A, and C is higher than that of other fish. In addition, loach is mild in nature, sweet in taste, and enters the liver, spleen and kidney. It also has high medical value. Therefore, in recent years, the export trade volume of loach has increased year by year, and the consumption of loach in China has also shown an upward trend. [0003] Since the natural loach resources are far from meeting people's consumption needs, the loach breeding industry has also begun to enter a period of ra...
