Problems solved by technology

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a method for breeding crucian carp fry based on net cages. Many, one fishpond can only breed one size of fry at a time, and it is also prone to pests and diseases, resulting in technical problems of low survival rate; through this technical solution, crucian carp fry can be hatched and cultivated in the same cage space at the same time, There is no need to transfer midway, and it can realize the large-scale production of crucian carp fry of different batches and specifications in different cages at the same time in a fish pond, so as to use limited land resources to efficiently realize high-density and high-yield hatching and cultivation of crucian carp fry , at the same time, the operation is simple and not easy to be infected with diseases, which improves the survival rate of crucian carp fry, thereby reducing the cost of fry cultivation

Embodiment 1

[0021] This embodiment is the crucian carp fry breeding method based on net cage, and concrete steps are:

[0022] Step 1. At the end of March 2018, install breeding cages in a pond with an area of ​​10.0 mu and an average water depth of 1.8 meters. Control the length, width and height of a single breeding cage to 6.0m×6.0m×1.0m. The sieve of box is 100 orders, and makes breeding net cage be in the area of ​​leeward and sunny, and control breeding net cage bottom more than 50cm from pond bottom, place more than a week;

[0023] Step 2. At the beginning of April, soak the fertilized crucian carp roe with a potassium permanganate solution with a mass concentration of 20PPM for 20 minutes, then place the roe on the mesh sheet, and extend the mesh sheet into the water surface in the breeding cage Below 20cm, place 10kg of fish eggs in each breeding cage;

[0024] Step 3: After the fish fry are completely out of the film in 4-7 days, take out the grid sheet, and exchange the breed...

Abstract

The invention discloses a carassius auratus fry breeding method based on a net cage, which aims to solve the technical problems that a carassius auratus fry breeding method in the prior art is complicated to operate, the occupied land area is large, a fish pond can only breed a species of fry at a time, diseases and insect pests are prone to occur, and the survival rate is low. The method comprises the following steps of: installing a breeding net cage in a pond in advance; placing soaked fish eggs on grid sheets; extending the grid sheets into the breeding net cage; performing water body exchange after the fry comes out of a membrane; feeding carassius auratus fry powder after a period of time; and then obtaining the carassius auratus fry. According to the technical scheme, the carassiusauratus fry can be simultaneously hatched and bred in a same net cage space, so that the carassius auratus fry is hatched and bred with high density and high yield by utilizing limited land resources;and meanwhile, the method is simple to operate and not susceptible to diseases, the survival rate of the carassius auratus fry is improved, and the cost for breeding the carassius auratus fry is further reduced.

Description

technical field [0001] The invention belongs to the technical field of freshwater fish culture, and in particular relates to a cage-based method for breeding crucian carp fry. Background technique [0002] Crucian carp belongs to Cypriniformes, and its meat is delicious and nutritious. It is one of the famous high-quality edible fish in my country and is deeply loved by consumers. Crucian carp is an omnivorous fish with the advantages of low temperature resistance, low oxygen resistance, and strong fecundity. It is cultivated all over the country, and the breeding modes are also diverse, which also makes the demand for crucian carp seed increase year by year. The method of breeding crucian carp fry under the prior art mode is to first hatch crucian carp eggs in a cement pond or hatching bucket, and then carry out water flower cultivation in the pond. This is the most common and effective way now, but this There are also certain disadvantages in this method, that is, its ope...
