Aquatic Animal Locomotor Behavior Test Method

Abstract

The invention discloses a test device and a test method for aquatic animal movement behavior. The test device comprises: a first main body, at least used to hold water for swimming aquatic animals; a second main body, placed in the first main body, It includes a plurality of branches communicating with each other, the plurality of branches define the movement space, water holes are formed on the side walls of the plurality of branches, and the second body communicates with the water holes through the water holes. The first main body is connected; the temperature adjustment unit is used to adjust the temperature of the water in the first main body; the gas volume adjustment unit is used to adjust the concentration of dissolved oxygen in the water in the first main body; the light adjustment unit is used to for adjusting the light intensity in the first body; the video acquisition unit is used for acquiring the motion video of the aquatic animals in the second body. The application of the invention can realize accurate and quantifiable statistical analysis on the motion behavior of aquatic animals, and improve the accuracy of the motion behavior test results.

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
