Problems solved by technology

[0005] Moreover, in the existing studies, the experiments of flow velocity, river bed quality and light were conducted in different experimental devices and under different experimental conditions. It is difficult to avoid the interference of other environmental factors other than the research factors, and the results of the data are inconsistent, which is not conducive to carrying out comparisons.

Embodiment 1

[0030] Dabry's sturgeon was used as the test fish to conduct the experiment of water flow velocity preference behavior.

[0031] 1. Preparations before the test: According to the attached figure 1 Set up a test device for testing the environmental preference behavior of fish, fill the water tank 1 with water, adjust the water intake of the water inlet pipe 2 and the displacement of the water outlet pipe 8 through the water pipe regulating valve 7 and the water outlet pipe regulating valve 11, and use the diversion barrier The plate 3 forms a corresponding diversion groove in the water tank 1, and the pressurized water tank 6 is supplied with water by the frequency conversion water pump 9 to form a stable pressure. When the water pressure in the pressurized water tank 6 needs to be adjusted, the frequency conversion water pump is adjusted by the frequency conversion regulator 10 The rotating speed and water pressure of 9 make the water pressure in the pressurized water tank 6 a...

Embodiment 2

[0041] Dabry's sturgeon was used as the test fish to carry out the river bed quality preference behavior experiment.

[0042] 1. Preparations before the test: According to the attached figure 1 Set up a test device for testing the environmental preference behavior of fish, use the upper diversion partition 3 and the lower diversion partition 12 to form a corresponding diversion groove between the water inlet pipe 2 and the outlet pipe 8, and pour water into the water tank 1. When the water is full, adjust the water intake of the water inlet pipe 2 and the discharge of the water outlet pipe 8 through the water inlet pipe regulating valve 7 and the water outlet pipe regulating valve 11. The pressurized water tank 6 is supplied with water by the frequency conversion water pump 9 and forms a stable pressure. When the water pressure in the tank needs to be adjusted, the rotating speed and the water pressure of the frequency conversion water pump 9 are adjusted by the frequency conver...

Embodiment 3

[0052] Dabry's sturgeon was used as the test fish to conduct the experiment of light preference behavior.

[0053] 1. Preparations before the test: According to the attached figure 1 Set up a test device for testing the environmental preference behavior of fish, use the upper diversion partition 3 and the lower diversion partition 12 to form a corresponding diversion groove between the water inlet pipe 2 and the outlet pipe 8, and pour water into the water tank 1. When the water is full, adjust the water intake of the water inlet pipe 2 and the discharge of the water outlet pipe 8 through the water inlet pipe regulating valve 7 and the water outlet pipe regulating valve 11. The pressurized water tank 6 is supplied with water by the frequency conversion water pump 9 and forms a stable pressure. When the water pressure in the tank needs to be adjusted, the rotating speed and the water pressure of the frequency conversion water pump 9 are adjusted by the frequency conversion regu...

Abstract

The invention provides a testing device and a testing method for testing environmental preference behaviors of fishes. The device is characterized in that water inlet pipes with a flow regulator and water outlet pipes with a flow regulator are respectively installed at the two ends of a water trough, one ends of the water inlet pipes are communicated with a pressure-bearing water tank, flow conditioning meshes are respectively installed at the communicating ports of the water inlet pipes which are communicated with the water channel, upper flow guide baffles are installed between the water inlet pipes and the water outlet pipes to form flow guide channels, isolating nets are installed at the front ends of the water inlet pipes and the water outlet pipes, and the pressure-bearing water tank is connected with a variable-frequency water pump and a variable-frequency regulator. The method comprises the steps of 1) preparation before testing; 2) testing and correction of the testing device; 3) testing of preference behaviors of fishes; 4) testing data acquisition and preference index calculation; 5) maintenance and cleaning of the device. The testing device and the testing method for testing the environmental preference behaviors of the fishes can realize researches on the preference behaviors under various environmental factors such as flowing speed, river bed materials and illumination according to different environmental factors which are distributed in an experimental area.

Description

technical field [0001] The invention relates to the field of fish behavior, in particular to a test device and a test method for testing the environmental preference behavior of fish. Background technique [0002] Fish behavior is a subject that studies the interaction of fish with the environment and other organisms. It has important guiding significance for fish resource protection and fish farming production. Fish preference behavior is an effective indicator to measure the fish's choice and preference for different thresholds of environmental factors, and it is an important content in the research on the protection of fish natural habitats and the design of fish passing facilities. Environmental factors such as water flow, river bed quality, and light are routine contents in the study of fish behavior preference. Research on fish preference behavior is based on the distribution frequency of fish in various environmental factors. Therefore, how to effectively eliminate ...
