Embodiment 1

[0030] see Figure 1-5 , an experimental device for testing the behavior of fish towards bubble curtains and lights. The main body of the experimental device is a multi-channel "U"-shaped experimental water tank 1 with a size of 410cmX300cmX35cm; It is four independent working areas; the bottom of the experimental water tank 1 is provided with a bubble tube 5, and the side wall is provided with a flashlight belt 4; the bottom of the experimental water tank 1 is connected to an air supply pump; , and connected with the air pipe 2; the flash light strip 4 is cemented on the inner wall of the experimental water tank 1; the front end of the experimental water tank 1 is provided with a block 10 and a rectifying grid 9.

[0031] In a preferred solution, the bubble tube 5 is made of PVC with a diameter of 10 mm, and bubble holes with a diameter of 1.2 mm are arranged above the tube wall, and the hole distance is 1 cm;

[0032] In a preferred solution, the bubble tube 5 can produce b...

Embodiment 2

[0039] Working condition 1: Exploring the tendency behavior of fish towards different density bubble curtains

[0040] In the experimental device for testing the tendency behavior of fish to bubble curtains and lights, working condition 1 only tests the tendency behavior of fish to bubble curtains of different densities. Before being officially used in the experiment, the air supply pump 11 was turned on 5 minutes in advance to generate bubble curtains of different densities in the four experimental areas a, b, c, and d respectively, and the densities were respectively: 0, 40, 80, 100 L / min. Where 0 is the contrast parameter.

[0041] When the bubble curtain enters a stable working state, 50 experimental fish are put into the adaptation area 12, and after the experimental fish adapt to the environment for 5 minutes, the block 10 is removed.

[0042] The experiment time is 1 hour, observe the activities of 50 experimental fish in each area, observe the pass rate, attempt rat...

Abstract

The invention discloses an experiment device and method for testing approach behavior of fishes on a bubble curtain and lamplight. The experiment device comprises an experiment water groove, wherein the inner part of the experiment water groove is separated into a plurality of channels with a U-shaped section through a plurality of flow splitting piers; a bubble pipe is arranged at the bottom of the experiment water groove; a flashing lamp belt is mounted on a vertical side wall of each channel; the bubble pipe is connected with an air supply pump through an air conveying pipe; an interceptingnet and a rectifying grid are arranged at the front end of the experiment water groove. The experiment device can be used for researching physiological response mechanisms of the fishes on a couplingeffect of various different factors and is applied to researches of basic ethology of the fishes.

Description

technical field [0001] The invention relates to the field of fish behavior, in particular to an experimental device and method for testing the behavior of fish toward bubble curtains and lights. Background technique [0002] With the construction of water conservancy projects and the damage of various pollutants to the water environment, the habitats on which fish depend are being seriously threatened, resulting in a rapid decline in the species and quantity of fish resources, and the protection of fish is imminent. Studying the behavioral response of fish to a specific environment is an important prerequisite for the protection of fish. It is an important basic research to explore the impact of bubble curtains and lights on fish behavior. Curtains and lights exhibit different response characteristics. At present, there are shortcomings such as single function, low efficiency, and inability to perform multi-factor coupling analysis in the device for studying fish's response...
