Experimental device and testing method for brave and exploration behaviors of fishes

Abstract

The invention relates to an experimental device and a testing method for brave and exploration behaviors of fishes. A testing device comprises a main water tank, the main water tank is of a long-strip-shaped tank structure, a starting area and a stimulant placing area are correspondingly arranged on the two sides of the interior of the main water tank, a testing area is arranged between the starting area and the stimulant placing area, a fish blocking door is installed between the starting area and the testing area, and the fish blocking door can block the fishes to enable water to pass through; the stimulant placing area and the testing area are completely separated by a transparent first partition plate, and an electrode device is installed on the first partition plate; and a plurality of transparent second partition plates are installed in the testing area and distributed on the two side walls of the testing area at intervals, so that a path of the fishes passing through the testing area is a zigzag path. The testing method comprises the following steps that the brave and exploration behaviors of the fishes are tested; the time required for the experimental fish to pass through each partition plate is counted; and the brave exploration index of the experimental fishes is calculated. According to the experimental device and the testing method for the brave and exploration behaviors of the fishes, the brave exploration behaviors of different fishes and influences of different irritants can be tested and evaluated.

Description

technical field [0001] The invention belongs to the field of fish behavior, in particular to an experimental device and a test method for fish bravery and exploration behavior. Background technique [0002] The bravery of fish and the desire to explore the external environment have a certain impact on its survival, reproduction and many other life history characteristics. Bold fish, for example, are more likely to explore novelty, discover new food sources, and deviate from their normal range of activities. For example, females and guppies are also more likely to mate with bolder males, and bolder breams engage in predator-checking behavior more frequently than timid individuals, and when confronted with predators, they also mate. Exhibited higher speed and more persistent foraging behavior. Testing the bravery and exploratory nature of fish and the impact of environmental conditions can not only help to understand their biological characteristics, but also provide some he...
