Abstract

The invention discloses a fish sample collecting device which comprises a supporting mechanism, a fixing mechanism and a collecting mechanism, the supporting mechanism and the collecting mechanism are correspondingly arranged, the fixing mechanism and the supporting mechanism are correspondingly arranged, the supporting mechanism comprises a floating platform, the floating platform floats on the water surface, and the fixing mechanism comprises a fixing anchor fixed underwater. The top end of the fixed anchor is fixedly connected with a floater through a noose, the floater is fixedly connected with a flow guide piece through a noose, and the floating platform is fixedly connected with the flow guide piece through a noose and fixedly connected with the collecting mechanism through a noose. The device can quantitatively collect fish samples with different inhabiting depths, can ensure that the collected fishes are in a survival state, meets different research requirements, and can release the fish samples after no-damage research, so that the damage to the fishes is reduced.

Description

technical field [0001] The invention relates to the technical field of fish investigation and research, in particular to a fish sample collection device. Background technique [0002] When investigating and studying the relationship between fish and hydrodynamics in river fish resources, according to the requirements of the research content, it is necessary to collect fish samples from different water layers in the river. According to the different habits of fish, different types and sizes of fish live in different water layers. In order to collect fish samples more comprehensively, it is necessary to collect samples of different water layers and different sizes. Generally speaking, when surveying and sampling fish in rivers, ground cages and gillnets are generally used for sample collection according to the different water layers in which the fish live. However, this survey method has its limitations. First, quantitative analysis cannot be prepared. Except for ground cages...
