Aquatic animal movement behavior testing device and method

Abstract

The invention discloses an aquatic animal movement behavior testing device and method. The device comprises a first main body, a second main body, a temperature adjusting unit, an air volume adjustment unit, an illumination adjusting unit and a video acquisition unit, wherein the first main body is at least used for containing aquatic animal swimming water, the second main body is arranged in thefirst main body and comprises a plurality of branches which communicate with one another, a movement space is defined by the plurality of branches, water passing holes are formed in the side walls ofthe plurality of branches, the second main body communicates with the first main body through the water passing holes, the temperature adjusting unit is used for adjusting the temperature of the waterin the first main body, the air volume adjustment unit is used for adjusting the concentration of dissolved oxygen in the water in the first main body, the illumination adjusting unit is used for adjusting the illumination intensity in the first main body, and the video acquisition unit is used for acquiring the motion video of the aquatic animals in the second main body. By applying the method and the device, accurate and quantitative statistical analysis of the aquatic animal movement behaviors can be realized, and the accuracy of movement behavior test results is improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a test device and a test method for the movement behavior of aquatic animals. Background technique [0002] Phenotype variability among individuals of different genotypes is an important scientific issue in morphology, animal breeding and breeding. Research results in model organisms such as Drosophila have shown that individuals with different genotypes have different preferences for locomotor behavior, and individual behavior preferences may be an important determinant of phenotypic variation. Aquatic animals are characterized by high heterogeneity, multiple allelic variations, and high heterozygosity. During the breeding process of aquatic animals, even if the breeding conditions are strictly controlled, there may be significant differences in the growth of individuals within the same family. Studying the movement behavior of aquatic animals has important guid...

Problems solved by technology

Most of the experimental containers are square or round, and aquatic animals move freely in them. It is difficult to accurately and quantitatively count the changes in their movement behavior, which leads to inaccurate test results and reduces the ability to guide aquatic animal breeding based on the movement behavior of aquatic animals. the value of
