Method for mainly culturing yellow catfishes and carrying out polyculture on other feeding fishes in pond

Abstract

The invention belongs to the technical field of aquaculture, and relates to a method for mainly culturing yellow catfishes and carrying out polyculture on other feeding fishes in a pond. The method is characterized in that a new netting method is designed, various feeding fishes can be cultured in the yellow-head catfish main culturing pond in a polyculture mode according to local conditions, and the unit culturing efficiency of the yellow-head catfish main culturing pond can be improved greatly. The method mainly includes the steps that a purse net is erected in front of a main fish, namely the yellow-head catfish, feeding machine according to the feeding area covered by the feeding machine; preferentially, 80% bait fed by the feeding machine can fall in a region surrounded by the purse net under the breezeless condition, wherein the purse set is made of polyethylene, and is 60m in length, 4m in height and 4cm in mesh, dense-net cylindrical polyethylene net pieces are sewn at the bottom of the purse net, the diameter of each dense net piece is 6cm, cobblestone are arranged in the dense net pieces as sinkers, the purse net is fixed into a closed circle through bamboo poles, the foot line reaches bottom mud, and the head line is exposed of the water surface by 80-100cm. The invention further provides a coordinated culturing mode and a specific method.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for mainly cultivating yellow catfish and other feeding fishes in a pond. Background technique [0002] There are various farming models of peltago catfish. At present, it is relatively mature, and the most popular and widely used methods are pond intensive culture, pond culture and net cage monoculture. The set culture of yellow catfish is mainly carried out in ponds of adult fish of four major domestic fishes or ponds of shrimps, crabs and soft-shelled turtles, and the amount of stocking shall not exceed 4500 fish / hm 2 , lower yields. The intensive cultivation mode of yellow catfish mainly includes monoculture in ponds, or interbreeding silver carp in the main pond for feeding on algae, or interbreeding a small amount of Chinese soft-shelled turtle in the main pond for higher economic benefits. , the Chinese soft-shelled turtle raised in nesting does...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art. The problem to be solved in the present invention is the problem of food-eating fish scrambling for yellow catfish feed in the same cultured water body, thereby affecting the unit culture efficiency of the main culture pond of yellow catfish
