Breeding method of snakehead

Abstract

The invention discloses a breeding method of snakehead. The method includes the steps of building a fish pond, wherein the distance between an upper limit water level sensor and a lower limit water level sensor of the side wall of the fish pond is 0.7 m, the distance between the upper limit water level sensor and the top surface is 0.4 m, and the distance between the upper limit water level sensorand the bottom surface is 2m; building anti-escape walls around the fish pond; maintaining the content of dissolved oxygen in pond water at 6 mg per liter, and maintaining the transparency at 30 cm;planting water floating plants on the water surface in the pond; using a 4% saline solution for soaking fry for 8 minutes, wherein the stocking density is 5,500 per mu; feeding the fry at 8 o'clock a.m and 5 o'clock p.m every day, wherein the daily feeding amount accounts for 5-8% of the total weight of snakehead; replacing water once every 15 days, wherein one third of the total water amount is replaced every time; carrying out large-scale water replacement once every one and half month, wherein 85% of the total water amount is replaced every time; carrying out disinfection on the fish pond every 20 days; fishing out snakehead with big size from the fish pond every three months; one and half year later, fishing out snakehead meeting the sale requirement for sale. According to the method,it is ensured that the snakehead contains abundant protein and fat, and meanwhile the survival rate and growth speed of the snakehead are effectively increased.

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 my country, 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. Existing many culture methods of snakeheaded fish at present, but most of them all have the low survival rate of snakeheaded fish, the slow growth rate, the defective that is difficult to breed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a me...
