Method for high-density culture of siniperca chuatsi in flowing water pond

Abstract

The invention relates to a method for high-density culture of siniperca chuatsi in a flowing water pond. The method is a culture method based on a circular flowing water pond and is characterized in that an aeration oxygenation device is additionally arranged in the flowing water pond, a set of power generating equipment is additionally arranged to serve as temporary emergency electrical power supply equipment, and four meshes or blow of steel wire screens are arranged at an water inlet of the flowing water pond and at an water outlet of the flowing water pond respectively, so that siniperca chuatsi is prevented from escaping; 20 meshes of polyethylene nettings are arranged on the outer sides of the steel wire screens so as to prevent forage fish from escaping. The culture method comprises the steps that firstly, before fish fingerling stocking, a culture pond is disinfected; secondly, the forage fish is put into the pond at the density of 100 thousand to 120 thousand per pond; thirdly, siniperca chuatsi fish fingerling is put into the flowing water pond at the density of 20 thousand per pond, and Hypophthalmichthys molitrix and Aristichthys nobilis are put into the culture pond; fourthly, daily feeding adopts management of normality, and disease control is conducted in a mode combined the way that the forage fish has to be disinfected before being put into the pond with the way that a biological agent is periodically used. By means of the method, intensive cultivation of siniperca chuatsi is achieved, the fishing difficulty of commercial fish is further reduced, the aquaculture water surface is saved, and aquaculture waste water zero-discharge is achieved.

Description

technical field [0001] The invention belongs to the technical field of fishery science application, and in particular relates to a method for high-density culture of mandarin fish in a flowing water pool. [0002] technical background [0003] The maturity of the artificial breeding technology of large freshwater fish has solved the problem of "eat without fish" and formed a theoretical system of artificial breeding and breeding of freshwater fish, which has made aquaculture unprecedented development in our country. The output is increasing year by year, but the price of bulk freshwater fish has been low for a long time, forming a dilemma for farmers to increase production but not increase income. In recent years, pond recirculating aquaculture developed by the American Soybean Association has developed rapidly, and the level of intensification has been further improved. The output of bulk species such as herring has doubled. However, due to the price of bulk fish, its econom...
