A kind of culture system of East China Sea silver pomfret

Abstract

The invention discloses a breeding system for silver pomfret in the East China Sea, aiming to solve the problems of low bait utilization rate and long-term sinking of the bait to the bottom of the pond to pollute the breeding environment during the silver pomfret breeding process. The invention includes a breeding pond and a feeding cylinder installed in the breeding pond. The lower part of the feeding cylinder is provided with a number of bait outlet nozzles, and a one-way cover is installed at the opening end of the bait outlet mouth. A bait squeezing piston is installed inside the cylinder, a piston cylinder is installed on the upper part of the feeding cylinder, the telescoping rod of the piston cylinder is connected with the bait squeezing piston, the feeding tube is connected to the outer wall of the feeding cylinder, and an axially penetrating air hole is arranged on the bait squeezing piston, and the lower end of the bait squeezing piston The position of the vent hole is connected to the one-way valve; the upper and lower parts of the outer wall of the feeding tube are rotated and connected to the rotating ring, and the rotating ring is connected to the fish-lure floating bar, and the transmission connection linkage mechanism between the telescopic rod of the piston cylinder and the rotating ring; the bait collecting bucket is installed under the feeding tube , the lower end of the bait collecting bucket is connected with the cleaning pipe.

Description

technical field [0001] The present invention relates to a kind of aquaculture technology, more specifically, it relates to a kind of East China Sea silver pomfret culture system. Background technique [0002] As one of the important candidate species for marine farming, silver pomfret has received extensive attention. The large-scale farming of silver pomfret is in line with the medium and long-term planning of mariculture in my country, and it is of great significance. During the breeding process of silver pomfret, it is necessary to feed the bait. The traditional feeding method is to directly put the bait downward from the top of the breeding pond. The utilization rate is low, and in many cases the bait sinks to the bottom of the pond before being eaten, which not only causes waste of bait, but also pollutes the breeding environment of the breeding pond due to long-term deposition of bait, which is not conducive to the healthy growth of silver pomfret.

Problems solved by technology

[0003] The invention overcomes the disadvantages of low utilization rate of bait in the breeding process of silver pomfret and the problem that the bait sinks to the bottom of the pond for a long time to pollute the breeding environment, and provides a breeding system for silver pomfret in the East China Sea. The utilization rate is high, avoiding the problem that the bait sinks to the bottom of the pond for a long time and pollutes the breeding environment
