Embodiment 1

[0017] An experimental device for studying fish behavior, the device includes a water tank, a reef body composition for simulating an artificial fish reef structure in the water tank and a central isolation plate 2 located in the center of the tank, one side of the central isolation plate 2 is an experimental area, The other side is the water flow area 1, and the experimental area and the water flow area 1 are separated by a grid 5 so that fish cannot enter the water flow area. The reef body composition 4 is located in the middle of the experimental area, and the experimental area is equally divided into the first An experimental area 3 and a second experimental area 6, that is, one end of the reef composition 4 is connected to the wall of the tank, and the other end is connected to the central isolation plate 2. The length of the tank (the direction parallel to the water flow) is 6m.

[0018] The device also includes a water body power supply device that makes the water body f...

Embodiment 2

[0027] The experimental device for studying fish behavior is exactly the same as in Example 1, but the reef composition used is the first structure in Example 1, and the distance between the single reef bodies is 28cm.

Embodiment 3

[0029] The experimental device for studying fish behavior is exactly the same as in Example 1, but the reef composition used is the first structure in Example 1, and the distance between the single reefs is 56.7cm.

Abstract

The invention discloses an experimental device for studying fish behavior, which belongs to technical field of fishery industry. The invention relates to a reef composition and the application in internal structure of a simulated artificial reef thereof, and mainly solves the problem in the prior art that: low reliability of research result is caused by that the reef model adopted in the study on fish-gather effect of the artificial reef can not reflect the actual structural characteristics of the artificial reef under flow situation; a single reef is designed to replace the beam structure in the actual artificial reef, the reef composition composed of different compositions of the single reef is used for stimulating the internal structure of the actual artificial reef, thereby truly reflecting the changes of flow field around artificial reef under the flow situation, and providing real and effective data for the study on fish-gather effect of the artificial reef.

Description

technical field [0001] The invention belongs to the technical field of fishery and relates to an experimental device for studying fish behavior. Background technique [0002] Artificial reefs are structures that people set up in the sea. Its purpose is to improve the marine environment and provide breeding, growth and development, feeding and other habitats for swimming organisms such as fish. To achieve the purpose of protection, multiplication and increase of catch. After the fish reef is put into the sea area, under the action of the ocean current, various flow patterns will be produced around the fish reef according to the structure and shape of the reef, which is the so-called flow pattern effect. Some reef-oriented fish (such as red sea bream , black sea bream, etc.) will choose habitats according to their preferred flow range, so the behavioral responses of some reef-tending fish in natural sea areas to artificial reefs are studied, and the reef types and flow veloc...
