Breeding method of black carp

Abstract

The invention relates to a breeding method of black carp. The method includes the following steps of firstly, preparing a breeding land, establishing a breeding pond, forming a water inlet and a wateroutlet in the two ends of the pond respectively, arranging anti-escape nets at the water inlet and the water outlet respectively, and putting flowing water flowing in the water inlet and flowing outof the water outlet in the pond, wherein the pH value of the water is 6.5-7.5, and the water depth is 1.5-2.5 m; secondly, conducting disinfecting treatment, wherein the pond is disinfected through quick lime before water is injected in the pond; thirdly, stocking fish fry; fourthly, putting in feed; fifthly, managing water quality, wherein the water temperature in the pond is controlled to be 25-30 DEG C, and optimal malin for water body is put in once very five days. By means of the method, the morbidity of the black carp can be reduced, the yield of pond breeding can be better improved, themethod is greener and safer, the meat quality and taste of the black carp can be improved, the black carp is not prone to getting sick, and the method has wide market prospects in application and promotion of aquaculture.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating black fish. Background technique [0002] Snakefish is a common edible fish in China, with large body, fast growth and high economic value. Black fish has few bone spurs, high meat content, and rich nutrition, which is higher in protein than chicken and beef. As a medicine, black fish has the functions of removing blood stasis, promoting regeneration, nourishing and recuperating, etc. After surgery, eating snakehead has the effect of promoting muscle growth, enriching blood, and promoting wound healing, and has very rich nutritional value. [0003] In recent years, the snakeheaded fish market has become popular, and pond cultured snakeheaded fish has gradually risen. The farming methods in the prior art generally adopt rearranged river ditches or artificially excavated ponds, and carry out breeding production through still water bodies. The breeding ...

Problems solved by technology

[0003] In recent years, the snakeheaded fish market has become popular, and pond cultured snakeheaded fish has gradually risen. The farming methods in the prior art generally adopt rearranged river ditches or artificially excavated ponds, and carry out breeding production through still water bodies. The breeding technology and breeding technology are relatively backward. The resources cannot be effectively utilized, and the quality and safety of aquatic products cannot be guaranteed. Because black fish have a large appetite and excrement, the accumulation of excrement at the bottom of the pond will quickly make the water quality of the pond fat. Under such an environment, there are a large number of plankton in the pond. Breeding, the water body in the pond will eventually suffer from hypoxia and deterioration. At present, farmers generally adopt high-density farming for economic benefits. High-density farming is more likely to cause a large amount of excrement to accumulate at the bottom of the pond, resulting in a rapid decline in dissolved oxygen in the pond and deterioration of water quality. To facilitate the survival of snakeheaded fish, farmers need to constantly change the water source in the pond to ensure a good living environment for snakeheaded fish. For convenience, some farmers spray chemicals on the water surface to kill plankton when the water pollution is serious. , to increase the dissolved oxygen in the pond. Although this method is simple, it will cause double pollution to the water quality in the pond and affect the quality of snakeheaded fish.
