Problems solved by technology

At present, many farmers still adopt traditional breeding methods for the cultivation of grass carp fingerlings. Due to the low survival rate of grass carp fingerlings, under the traditional cultivation method, grass carp fingerlings have many diseases and high mortality rates, and they can obtain high yields. It is difficult and the economic benefits are not good, which seriously affects the enthusiasm of fish farmers to raise grass carp and winter fillets

Embodiment

[0019] The specific cultivation method is as follows:

[0020] a) Clearing ponds and water quality for fertilization. Clearing ponds should be carried out in mid-April. First, use high-pressure water guns and sludge pumps to remove excess silt to keep the silt about 15cm thick. Then drain the pond water and expose the bottom of the pond for 15 days. Then Use 75kg / 667m 2 After the quicklime is mixed with water, the whole pool is sprayed for disinfection. The selection of water quality for fertilization should be carried out after 4 days in the clear pond. First fill the pond with new water until the water depth is 60cm. After 7 days, apply microbial fertilizer 5kg / 667m 2 With chlorella species 500mL / 667m 2 , Cultivate the pool water into oily green, keep the water tender and refreshing.

[0021] b) Grass carp summer flower fry are stocked. Stocking grass carp summer flower fry is carried out at the end of May, and 100g / 667m is used 2 days before stocking. 2 Sprinkle EM bact...

Abstract

The invention provides a breeding method of grass carp winter fingerlings. The breeding method includes following steps: a), cleaning a pond and fertilizing water; b), stocking grass carp summer fry; c), artificially injecting grass carp vaccine; d), scientifically feeding feedstuff; e), using a microbial preparation to regulate water quality; f), performing daily management. The grass carp vaccine is injected artificially, and the microbial preparation is used to regulate the water quality, so that breeding environment is improved, diseased fishes are reduced, high yield of the grass carp winter fingerlings is realized and quite remarkable breeding benefit is obtained.

Description

technical field [0001] The invention relates to a method for cultivating fish fingerlings, in particular to a method for cultivating grass carp winter filleted fingerlings, and belongs to the technical field of aquaculture. Background technique [0002] Grass carp is a typical herbivorous fish, and adult fish mainly eat aquatic plants in a natural state. Under artificial feeding conditions, they are fed with all kinds of aquatic plants, terrestrial grasses and various concentrated feeds. Because of its rapid growth and wide source of feed, it has become one of the four major domestic fish in freshwater farming in China. Grass carp has a long history of breeding in my country. It has the advantages of fast growth, large size, tender meat, delicious taste, and low breeding cost. It is favored by farmers and consumers. [0003] The quality of grass carp winter fillet fingerlings directly affects the quality and output of adult fish farming. At present, many farmers still ado...
