Embodiment 1

[0016] Such as figure 1 As shown, a special fishing net for recirculating culture barrels includes a connecting rod 1, a fishing net 2 and a counterweight 3; a fishing net 2 is arranged between the connecting rods 1, and a counterweight 3 is arranged at the lower end of the fishing net 2.

[0017] There are two connecting rods 1, and the two sides of the fishing net 2 are respectively fixed on one connecting rod 1.

[0018] The counterweights 3 are evenly distributed on the lower end of the fishing net 2 . The fishing net 2 is a square fishing net.

[0019] The length of the square fishing net is 120%-150% of the diameter of the circular culture barrel, and the width is equal to the height of the barrel.

[0020] The length of the square fishing net is 120%-150% of the width of the square culture barrel, and the width is equal to the height of the barrel.

[0021] The connecting rod 1 is a PVC pipe.

Abstract

The invention relates to a fishing net special for a circulating aquaculture barrel and belongs to the technical field of aquaculture. The fishing net special for the circulating aquaculture barrel comprises connecting rods, a fishing net and counter weights, wherein the fishing net is arranged between the connecting rods; and the counter weights are arranged at the lower end of the fishing net. The quantity of the connecting rods is two, and two sides of the fishing net are respectively fixed on one connecting rod. The counter weights are uniformly distributed at the lower end of the fishingnet. The fishing net is square. The fishing net special for the circulating aquaculture barrel is simple in structure and low in cost. Compared with the traditional method, the fishing net disclosed by the invention is capable of efficiently completing fishing, saving the time and process and reducing stress response and damage of manual operations on experimental fishes.

Description

technical field [0001] The invention relates to a special fishing net for a circulating culture tank, which belongs to the technical field of aquaculture. Background technique [0002] In order to ensure the accuracy and repeatability of the experiment, when harvesting or transferring experimental fish during aquaculture experiments, gentle capture methods should be adopted as much as possible to reduce the stress response and damage of experimental fish caused by human manipulation. The common method is to catch by dredging or directly draining the water. Fishing by dredging nets has high technical requirements for operators, otherwise it will cause great damage and stress to experimental fish. Drain the water capture directly, time consuming and waste water. In addition, due to breeding needs, it is hoped that some experimental fish can be transferred or captured. The two methods will cause stress and damage to the remaining fish that continue to be cultured, affecting s...
