Problems solved by technology

[0002] There are many testing methods for evaluating the toxicity of chemical substances, including acute toxicity test, subacute toxicity test, subchronic toxicity test, etc., but these methods can only conduct targeted tests on a certain characteristic of chemical substances, and testing the toxicity of a chemical substance requires multiple groups of the above-mentioned The evaluation test is carried out comprehensively, the scope of application is narrow and the test efficiency is low

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0024] Foraging behavior is the survival instinct of animals, which mainly depends on the coordination of nervous system and motor system. The damage to the nervous system and motor system of fishes exposed to chemical substances can be reflected in the changes of foraging behavior. Therefore, the present invention evaluates the toxicity of the chemical substance by testing the change of the foraging behavior of the fish after exposure to the chemical substance, and judging the damage of the test chemical substance to the nervous system, motor system and other systems of the fish.

[0025] An embodiment of the present invention provides a method for testing fish foraging behavior, including: providing a test area; wherein...

Abstract

The invention discloses a fish foraging behavior testing method and device, and the method comprises the steps: providing a testing region, wherein the test area comprises a first area and a second area; before testing, isolating the first area and the second area from each other; putting the tested fish into water containing chemical substances, fishing out the tested fish after a preset duration, and then putting the tested fish into the first area; putting bait into the second area; during testing, enabling a test fish to pass through the through hole between the first area and the second area and enter the second area from the first area; counting the number of the test fishes entering the second area from the first area in each preset counting period, and calculating the percentage of the number of the test fishes entering the second area from the first area in the total number of the test fishes to obtain test data; and performing data processing on the test data to obtain a curve of the influence of the chemical substances on the foraging behavior of the tested fish.

Description

technical field [0001] The invention belongs to the field of evaluation and testing of chemical substances, and in particular relates to a fish foraging behavior testing method and testing device. Background technique [0002] There are many testing methods for evaluating the toxicity of chemical substances, including acute toxicity test, subacute toxicity test, subchronic toxicity test, etc., but these methods can only conduct targeted tests on a certain characteristic of chemical substances, and testing the toxicity of a chemical substance requires multiple groups of the above-mentioned Evaluation tests are conducted comprehensively, with narrow scope of application and low test efficiency. [0003] The behavior test of fish, especially the model species zebrafish, is an important part of the toxicity evaluation of chemicals, drugs, pesticides and other chemicals, especially the neurotoxicity evaluation. The development of simple, fast and highly sensitive fish behavior te...
