Problems solved by technology

[0002] Now, when freshwater fish is fished, many small fish that have not grown up will be brought in. Because a large number of small fish are caught, it is a devastating blow to wild freshwater fish and seriously damages the ecological balance; for freshwater fish farming, there will be a serious reduction in production, which will seriously affect economic benefits

Abstract

Freshwater fish classified fishing experiment device and method of use. An experimental device for classifying and fishing freshwater fish, comprising: an upper beam and a lower beam, the upper beam and the lower beam are connected to each other through a vertical bar, and a set of horizontal beams are arranged vertically on the vertical bar. Through hole, the horizontal through hole is connected with the stay wire, the left side of the upper cross beam is connected with the left tie rod, the right side of the upper cross beam is connected with the right tie rod, and the left tie rod and the right tie rod are both opened with Rope-through hole, the stay wire passes through the rope-through hole to connect the pull ring, the upper beam connects to the distance pull ring, and the distance pull ring passes through the distance stay rope. The invention is used for classified fishing of freshwater fish.

Description

Technical field: [0001] The invention relates to an experimental device for sorting and fishing freshwater fish and a method for using it. Background technique: [0002] Nowadays, when freshwater fish is fished, many small fish that have not grown up will be brought in. This is commonly known as extreme fishing, which will seriously affect the growth of wild freshwater fish and the cultivation of freshwater fish. Because a large number of small fish are caught, it is difficult for wild freshwater Fish is a devastating blow, which seriously damages the ecological balance; for the cultivation of freshwater fish, there will be a serious reduction in production, which will seriously affect economic benefits. Invention content: [0003] The object of the present invention is to provide a freshwater fish sorting and fishing experimental device and a method of use that can catch freshwater fish of different sizes according to needs, not only maintain ecological balance, but also ...
