Net-hauling fish collection method for pond with base membrane laid

Abstract

The invention discloses a net-hauling fish collection method for a pond with a base membrane laid. The method is characterized by comprising following steps: S1, a hauling net is arranged in the pondwith the laid base membrane, a shovel-shaped pendant is arranged at the bottom of the hauling net, and a first net cuff is arranged on the outer side of the hauling net; S2, shoals of fish are drivento gather by the hauling net; S3, a net cage is arranged beside the outer side of the hauling net, and a second net cuff corresponding to the first net cuff is arranged on one side of the net cage; S4, the first net cuff and the second net cuff are butted; S5, the hauling net is closed and the shoals of fish are driven to the first net cuff and the second net cuff to enter the net cage; S6, the first net cuff and the second net cuff are removed, and the second net cuff is tightened. The bottom of the hauling net is prevented from being pulled up, the shoals of fish are prevented from escapingfrom the bottom of the hauling net, so that the fish collection efficiency is improved, the operation cost is reduced, all that is required is to drive the shoals of fish to enter the first net cuff when the shoals of fish are driven to enter the net cage, measures such as fishing and the like causing damage to the shoals of fish are not needed, and the shoals of fish are prevented from being damaged in the fish collection process.

Description

technical field [0001] The invention relates to the field of pond fishing operations, in particular to a method for collecting fish by pulling nets in ponds with bottom membranes laid. Background technique [0002] In the process of aquaculture production, how to successfully catch the grown fish or cultivated seedlings is a very important task. All of them are harvested from ponds, such as the grouper and basket fish that are currently being farmed on a large scale. They were originally coral reef fish, timid by nature, and highly vigilant. The bottom pole of the net is pulled up or there is a gap at both ends and runs out of the net, or the fish body is injured or lacks oxygen during the fish harvesting process, which will eventually lead to infection or even death of the fish body. [0003] In recent years, with the upgrading of breeding technology and facilities, the scale and density of farming have gradually increased. In order to adapt to these changes, most farmers ...

AI Technical Summary

Problems solved by technology

[0004] Using the traditional net pulling method to collect fish, when the operator drags the net, it is easy to pull up the bottom of the net, causing the fish to escape from the raised gap, which reduces the efficiency of fish collection and increases the operating cost
