Problems solved by technology

In addition, the net clothes of the existing nets use cotton net or nylon net, but both have the following disadvantages: although the cotton net has the smallest operation on the fish body, it has a high water absorption rate, is heavy to use, and has a high operating intensity, so it is not suitable for long-term use. Operation; Nylon net is strong and durable, and its water absorption rate is not high, but it is very easy to catch fish fins, causing fish casualties

Abstract

The invention belongs to the technical field of fish harvesting in the process of artificial breeding, in particular to a net tool used for fishing fish in medium and small rivers and operation methods of the net tool. The net comprises a net body, a sink, a float, a fixing rod, a rotary rod, an upper wire rope and a lower wire rope. The operation methods of the net tool include a vertical bank slope net pulling method, a semi-enclosed net pulling method and a full-enclosed net pulling method, wherein the specific operation methods include net tool assembly, net laying location selection, netlaying location selection and fishing. The net tool is designed according to the actual width of the river channel, the water flow size, the water depth, the flow speed and the fish habit. The operation is simple and convenient; fewer operators are required; the operation speed is fast and the fishing success rate is high; the net tool has few net-hanging fishes and little damage to parent fishes,and the captured fishes have representative population structure; and the fishing tool has small water absorption rate and light weight of materials, and is suitable for multiple times and long-timeoperation.

Description

technical field [0001] The invention belongs to the technical field of fish harvesting in the process of artificial breeding, and in particular relates to a net used for fishing fish in small and medium rivers and an operation method thereof. Background technique [0002] There are many kinds of nets for river fishing, such as ground nets, gill nets, and cast nets, but there are some disadvantages according to the actual conditions of the natural river water environment, water depth, and current. Most of the designs of floor nets are more suitable for use in rivers and lakes, but it is difficult to operate under running water conditions. Gillnet is an extremely easy-to-operate net, but it has certain selectivity for the size of the caught individuals. Casting nets are suitable for small-scale fishing and are suitable for operations in waters with high fish density. [0003] In the process of artificial breeding of naked carp in Qinghai Lake, in order to obtain high-quality...
