Breeding method for grass carp with clean water

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...

Problems solved by technology

[0006] In recent years, with the unremitting efforts of agricultural science and technology workers and farmers, some breeding methods such as lakes, cages, and ponds have been explored. Although these farming methods have partially increased the output of grass carp, due to the critical output Not high, which affects the breeding enthusiasm of farmers
