Portable aquaculture body recovery device and use and storage method thereof

Abstract

The invention relates to a portable aquiculture body recovery device and a use and storage method thereof. The transverse frame strips of a hollow box-type frame are multi-section telescopic frame strips, and all the transverse frame strips can be synchronously telescopic to change the width of the whole frame. The front side of the frame is provided with three rotating plates which can independently extend and retract respectively, and the three rotating plates are respectively and rotationally arranged at the front side of the frame. The left side face and the right side face and the bottomside face of the frame are respectively covered with the escape prevention net, slots are formed from the top of the frame downwards to the front and the back at intervals and are respectively and movably inserted into the net door plate and the net bag plate. A driving motor is fixedly arranged at the top of the frame, a walking driving wheel and a walking driven wheel which are driven by the driving motor are arranged at the bottom of the frame, and the walking driven wheel is arranged at the left side and the right side of the frame. The device reduces the labor intensity and the difficultyof fish recovery in an intensive culture mode, and improves the recovery efficiency. The stress generated in the fishing process of the fish is reduced, and the damage caused by mutual extrusion andtearing and biting of the fish bodies is avoided.

Description

technical field [0001] The invention relates to the technical field of fishery, in particular to a portable aquaculture body recovery device and its use and storage method. Background technique [0002] At present, the recovery of aquaculture bodies in laboratory tanks mainly adopts net recovery, but different aquaculture bodies have different shapes and swimming speeds, and the traditional recovery method of aquaculture bodies is labor-intensive and low in efficiency. Especially for small-sized aquaculture bodies, due to their small size and strong ability to avoid fishing nets, it is difficult to recover, and frequent fishing operations will increase the stress of aquaculture bodies, and improper operation may even affect experimental aquaculture. The damage caused by the body causes the survival rate of experimental samples to be low; the recovery of aquatic organisms such as fish in intensive culture ponds is mainly carried out by manual pulling nets, which has a high ca...

[0002] At present, the recovery of aquaculture bodies in laboratory tanks mainly adopts net recovery, but different aquaculture bodies have different shapes and swimming speeds, and the traditional recovery method of aquaculture bodies is labor-intensive and low in efficiency

Especially for small-sized aquaculture bodies, due to their small size and strong ability to avoid fishing nets, it is difficult to recover, and frequent fishing operations will increase the stress of aquaculture bodies, and improper operation may even affect experimental aquaculture. body damage, resulting in a low survival rate of experimental samples; the recovery of fish and other aquatic organisms in intensive aquaculture ponds is mainly carried out by manual pulling nets, which has a high catch at one time and is labor-intensive

At the same time, a large number of aquaculture bodies will squeeze each other when they gather at high density in the net. For ferocious aquatic organisms (such as Chinese soft-shelled turtles), there will also be a phenomenon of biting each other, causing varying degrees of body surface damage or even death, affecting the selling price and giving Farmers cause economic losses to varying degrees
