Aquaculture net cage improving utilization ratio of baits

Abstract

The invention relates to the technical field of an aquaculture net cage, and particularly discloses an aquaculture net cage improving the utilization ratio of baits. The aquaculture net cage comprises a net cage fixing support and nettings, wherein the net cage fixing support comprises four upright rods; the upper ends of the nettings are provided with floating blocks; the upper end and the lower end of each upright rod are respectively provided with an upper fixing seat and a lower fixing seat; a steel rope is arranged between each of the upper fixing seats and the corresponding lower fixing seat; sliding rings are arranged on each of the steel ropes; the sides of the nettings are respectively connected with the sliding rings through ropes; the bottom parts of the nettings are respectively provided with heavy blocks; a plurality of mutually parallel baffle plates are arranged between the outer sides of every two adjacent upright rods; the baffle plates and the upright rods are rotationally connected; the lower side face of each baffle plate is connected with the corresponding upright rods through pull springs; two ends of each baffle plate are also respectively provided with a pull rope; the pull ropes and the baffle plates are all fixedly connected; the upper end of each pull rope is provided with a hanging hook; the upper end of each upright rod is provided with an upper hanging hook seat; a lower hanging hook seat is arranged on each of the upper fixing seat. Therefore the aquaculture net cage has the beneficial effects of effectively preventing the baits from being washed away by water flow, improving the utilization ratio of the baits, and lowering the feeding cost.

Description

technical field [0001] The invention relates to the technical field of aquaculture net cages, in particular to an aquaculture net cage which improves the utilization rate of bait. Background technique [0002] With the development of the aquaculture industry, cage culture is becoming more and more popular. Fish culture in cages is a highly intensive farming method that applies the technology of dense stocking and intensive farming in ponds to large water surfaces with superior environmental conditions to achieve high yields. It can save the land and labor needed to excavate fish ponds. After investment, the return is quick. Fish culture in net cages can make full use of water and erbium organisms. It implements polyculture, dense culture, high survival rate, and can achieve high production goals. The feeding cycle is short , easy management, flexible maneuvering, and easy operation. The density of fish in the cage is relatively high. In order to maintain sufficient dissolved...
