Embodiment 1

[0027] A culture method for grass carp in clear water, comprising the steps of:

[0028] (1) Selection and cleaning of ponds: The main grass carp in the pond requires a square fish pond, which requires convenient drainage and irrigation. The effective breeding area is 15 mu, the water depth is 2 meters, and there is 0.07 meters of silt at the bottom of the pond. The first four weeks before stocking fish species Disinfect with quicklime clear pond, drain and expose to the sun for three weeks after disinfection, and then inject water. When injecting water, use a grid to filter at the water inlet to prevent wild fish from entering the pond. The water source should be selenium-rich stream water with sufficient water volume and clean water quality without pollution;

[0029] (2) Fry stocking: select 1.2kg fish fingerlings, the fish fingerlings are neat, uniform, and disease-free fry, start stocking around February, the stocking density is controlled at 2 tails / square meter, and use ...

Embodiment 2

[0035] A culture method for grass carp in clear water, comprising the steps of:

[0036] (1) Pond selection and cleaning: The main grass carp in the pond requires a square fish pond, which requires convenient drainage and irrigation. The effective breeding area is 18 mu, the water depth is 2.5 meters, and there is 0.1 meters of silt at the bottom of the pond. The first four weeks before stocking fish species Disinfect with quicklime clear pond, drain and expose to the sun for three weeks after disinfection, and then inject water. When injecting water, use a grid to filter at the water inlet to prevent wild fish from entering the pond. The water source should be selenium-rich stream water with sufficient water volume and clean water quality without pollution;

[0037] (2) Fry stocking: select 1.5kg fish fingerlings, the fish fingerlings are neat, uniform, and disease-free fry, start stocking around February, the stocking density is controlled at 2 tails / square meter, and use 5% ...

Abstract

The invention provides a breeding method for grass carp with clean water. The method comprises the following steps: (1) selecting and cleaning a pond; (2) stocking juvenile fish; (3) feeding with fodder; (4) managing water quality; (5) controlling diseases; and (6) fishing in due time. The breeding method provided by the invention is a sustainable developing grass carp breeding method. According to the method, all aspects are finely designed, so that the grass carp is strong, can quickly grow, tastes soft and nice, is rich in nutrition and difficultly falls ill; the yield of the grass carp can be increased; the method has higher promotion value; according to the invention, the fodder is reasonable in formula, balanced in nutrition and suitable for grass carp; especially, selenium-rich raw materials are added, so that the digestive absorption of grass carp for selenium is boosted; compared with the common grass carp, the grass carp has the advantages that the selenium content is increased by 10 times, the healthcare function is obviously enhanced, the immunity is boosted and the grass carp can resist oxidation, ageing and caner.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for cultivating grass carp in clear water. Background technique [0002] Because of its delicious meat and rich polyunsaturated fatty acids, fish products have become a kind of meat product that is very beneficial to human health. Its consumption is increasing day by day and exceeds the growth rate of pork, beef and mutton, and it has become the main source of meat food. Grass carp has the characteristics of thick meat, white meat, delicious taste, and fewer intermuscular spines. At the same time, it grows rapidly, has small price fluctuations, and has a broad market prospect. On the other hand, grass carp also has good processing quality. In recent years, the output has continued to increase, and the annual output has exceeded 4 million tons, accounting for about 20% of the total breeding. [0003] Grass carp belongs to the genus Grass carp of Cyprinidae Cyprinid...
