Experimental use fish observation water tank

Abstract

The invention belongs to the field of fisheries research equipment, and in particular relates to an experimental use fish observation water tank. The water tank comprises a large sink, a small sink, a bracket, a fish placement netting frame and a miniature high speed camera, the small sink is arranged inside the large sink, the small sink is fixed through the bracket on the large sink, and the fish placement netting frame is arranged inside the small sink. The fish observation water tank has the large sink and the small sink for convenient water changing, in the water changing process, the fish condition is not affected, the water flowing role can be produced, and the flow speed can be changed; the water level of the small sink is adjustable, users can adjust according to different fish needs; the cross net board and the longitudinal net board can be moved in the net frame to regulation the size of the net frame, the regulation precision is high, and the range is large, so that the uses for different sized fishes can be met.

Description

technical field [0001] The invention belongs to the field of fishery research equipment, and in particular relates to an experimental fish observation tank. Background technique [0002] In fishery research, it is often necessary to observe the behavior of various types of fish to draw some conclusions about the living habits and various abilities of the fish. The traditional experimental fish observation tank has a simple structure, consisting of only one tank and a net frame in the tank. The net frame is surrounded by four pieces of steel mesh, and the corners are tightened and fixed by steel bars. Such fish observe the water flow in the tank to be static, and there is no way to observe the dynamic performance of the fish in the action of running water. The water quality is easy to deteriorate, and the bottom of the tank is easy to accumulate silt. Moreover, there are many types, and there are differences in observation and recording parameters. The traditional fish obser...

Problems solved by technology

This kind of fish observes the water flow in the tank to be static, and observes the dynamic performance of the fish in the action of flowing water. The water quality is easy to deteriorate, and the bottom of the tank is easy to accumulate silt.

Moreover, there are many types, and there are differences in observation and recording parameters. The traditional fish observation tank for experiments has poor observation effect, cannot adjust the size of the net frame, cannot measure the length of the fish, and cannot replace the steel mesh according to the size of the fish. Living habits and various abilities bring great inconvenience, which affects the accuracy of observation conclusions and fishery research
