Young silvery pomfret breeding device and method in East China Sea

Abstract

The invention discloses a young silvery pomfret breeding device and method in the East China Sea, and aims to overcome the defects that in the silvery pomfret breeding process, the utilization rate ofbaits is low, and the baits sink to the bottom of a pond for a long time to pollute the breeding environment. The young silvery pomfret breeding device comprises a culture pond and a feeding barrel,a plurality of bait outlet nozzles are arranged at the lower portion of the feeding barrel, one-way cover pieces are installed at the opening ends of the bait outlet nozzles, a bait squeezing piston is installed in the feeding barrel, a bait storage barrel and a piston cylinder are installed at the upper portion of the feeding barrel, a bait squeezing plug is installed in the bait storage barrel and connected with a piston cylinder telescopic rod, and a piston rod is connected between the bait squeezing plug and the piston cylinder telescopic rod; a feeding hole and a discharging hole are formed in the bait storage barrel, a bait squeezing cavity is formed between the position, below the bait squeezing piston, in the feeding barrel and the bottom of the feeding barrel, a through hole is formed in the bait squeezing piston, a feeding pipe is connected between the upper end of the through hole and the discharging hole, and the lower end of the through hole is connected with a one-way valve plate; and the piston cylinder telescopic rod moves downwards to drive the bait squeezing piston to move downwards to squeeze out the baits in the bait squeezing cavity through the bait outlet nozzle.

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 juvenile culture device and method. 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....

AI Technical Summary

Problems solved by technology

[0003] The invention overcomes the disadvantages of low bait utilization rate in the silver pomfret breeding process, and the bait sinks to the bottom of the pond for a long time to pollute the breeding environment, and provides a breeding device and method for East China sea silver pomfret juveniles. The utilization rate of bait is high in the fish breeding process, avoiding the problem of bait sinking at the bottom of the pond for a long time and polluting the breeding environment
