Abstract

The invention discloses a fish catcher which comprises an induction hole (1), a fish catcher attached cavity (2), a fish inlet (3), a fish catcher main body (4), a bait bottle (5), a fish catcher cover (6) and a lifting rope (7), wherein the induction hole (1) is in a cone structure and made of a transparent material, holes having the diameter being 2mm are distributed on the induction hole (1), and seven holes are arranged per square centimetre; the induction hole (1) is combined with the fish catcher main body (4) to form the fish catcher attached cavity (2); and the diameter D1 of the induction hole (1) is 96 millimetres, and the diameter D2 of the fish inlet (3) is 36 millimetres. The fish catcher disclosed by the invention aims at small juvenile fishes (having a length of 15-70 millimetres), and the purpose of catch is to observe and research the juvenile fishes as living samples. The fish catcher is small in size, convenient in use, immediate in catch while being used, suitable for various water bodies, and especially suitable for catch and research for fishes in forest mountain streams.

Description

technical field [0001] The invention relates to a fishing device, in particular to a juvenile fishing device. Background technique [0002] The catch object of the prior art is mainly adult fish, and the purpose of catching is mainly for eating. The utensils require a large volume, need to have a barb structure, and some also need to be assembled with a fishing net. In actual use, barbed structures and nets are effective for adult fish but not for juvenile fish. Moreover, the prior art has a long capture time interval, and the capture effect is quite different between daytime and nighttime. [0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0004] The technical problem to be solved by the invention is to provide a fishing gear for the deficiencies of the prior art. [0005] Technical scheme of the present invention is as follows: [0006] A fishing trap, comprising an induction mouth (1), a fishing trap attachmen...
