An experimental device for the study of fish behavior under water pressure stress

Abstract

The invention discloses an experimental facility for research of behaviors of fishes threatened by the water pressure. The experimental facility comprises a cylinder body, a cylinder cover, a control box, a camera A and a camera B. The control box is fixedly arranged outside the cylinder body. The camera A is fixed to the inner wall of the cylinder cover. The camera B is fixed to one side of the cylinder body. Both the camera A and the camera B are connected with a computer through image collection cards. The control box comprises an internal controller and a control panel. The cylinder body is provided with a water inlet pipe and a water outlet pipe. The water inlet pipe is provided with a solenoid valve A and an automatic boosting pump. The water outlet pipe is provided with a solenoid valve B. The cylinder body is communicated with a pressure transmitting meter. The pressure transmitting meter, the solenoid valve A and the solenoid valve B are connected with the internal controller through circuits. A heating rod and a water quality detection sensor are fixed in the cylinder body. The cylinder cover is provided with a top light. The top light, the heating rod and the water quality detection sensor are connected with the internal controller through wires. The experimental facility is simple in structure, convenient to operate and capable of achieving the research of the influence on the behaviors of the fishes of the moment when the fish habitat is changed.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring equipment, in particular to an experimental device for researching fish behavior under water pressure stress. Indicators and an experimental device for observing and recording the behavior of fish in the fish tank. Background technique [0002] Over the years, the construction of dams has brought certain benefits to mankind. However, for the fishes living in the upstream and downstream of the dam, in the process of releasing water from the dam, the fishes located in the upstream and downstream of the dam will change their living environment due to the sudden change of the water level, such as water Pressure, temperature, light, etc., sudden changes in these factors will affect it. If it is very difficult to directly detect and observe the impact in the wild, it is possible to conduct research indoors by simulating the moment of fish habitat change, but there is no such system fo...

However, for the fishes living in the upstream and downstream of the dam, in the process of releasing water from the dam, the fishes located in the upstream and downstream of the dam will change their living environment due to the sudden change of the water level, such as water Pressure, temperature, light, etc. Sudden changes in these factors will affect it

If it is very difficult to directly detect and observe the impact in the wild, it is possible to conduct research indoors by simulating the moment of fish habitat change. However, there is no such system for studying the impact of the moment of fish habitat change indoors.
