Temporary culture type shellfish proliferation apparatus

Abstract

The invention discloses temporary culture type shellfish proliferation apparatus, and aims to provide the temporary culture type shellfish proliferation apparatus which can effectively prevent shellfish fry from being carried away easily by an ocean flow and being distributed to a sea-bed area which is not suitable for attachment and growth of shellfish fry before attachment is realized, and accordingly reduces the survival rate of the shellfish fry. The temporary culture type shellfish proliferation apparatus comprises a counterweight base and a rotary shellfish temporary culture mechanism, and the rotary shellfish temporary culture mechanism comprises a rotary mounting rod which is arranged on the counterweight base through a horizontal shaft, a shellfish temporary culture box arranged on the rotary mounting rod and a buoyancy device arranged on the rotary mounting rod; one side surface of the shellfish temporary culture box is provided with a flow discharging opening and a sealing cover plate used for sealing the flow discharging opening; and the buoyancy device comprises a columnar buoyancy block, a cantilever rod connected with the end part of the rotary mounting rod, a floating block mounting rod which is parallel to the cantilever rod, and a first connecting rod which is connected with the end part of the cantilever rod and the end part of the floating block mounting rod.

Description

technical field [0001] The invention relates to a multiplication device, in particular to a temporary raising shellfish multiplication device. Background technique [0002] Artificial shellfish ecological restoration means that shellfish are released into natural marine waters where shellfish resources have declined after artificial breeding and breeding, so that the natural population of shellfish can be restored. At present, the general method of artificial shellfish ecological restoration is to pack the seedlings, transport them to the release sea area by a transport ship, and then manually sow the seedlings in a certain sea area. Since it takes about one to two weeks for shellfish seedlings to attach to the seabed, this makes it easy for shellfish seedlings to be taken away by ocean currents and randomly distributed to various places on the seabed. However, many seabeds are not suitable for the attachment and growth of shellfish seedlings (such as bottom mud sea areas),...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method that can not only effectively prevent shellfish seedlings from being easily taken away by ocean currents before attachment, and be distributed to seabed areas that are not suitable for shellfish seedling growth, but also reduce the survival rate of shellfish seedlings. problem; and the structure is simple, which can effectively avoid the problem that the mesh box cover cannot be opened or opened in advance due to poor sealing.
