Problems solved by technology

However, there is a certain blindness and subjectivity in the current process of building fish shelters, and the fish shelters created cannot meet the habitat needs of the target organisms to a large extent, which not only wastes human and material resources, but is also difficult to achieve. The original intention of biological protection

Abstract

A water tank and method for testing the habitat suitability of fish shelters in waterway engineering, which includes a test tank, a lifting mechanism, a flow-making device and a wave-breaking device, and the flow-making device and the wave-breaking device are respectively arranged at both ends of the test tank , the lifting mechanism located outside the test tank is used to open and close or install the first fish gate and the second fish gate. The flow generator and the wave dissipation device are connected to each other to form a circuit, and the flow creation device creates a stable water flow to the wave dissipation device. One end flows, and the ripples of the flowing water body are digested by the wave elimination device and then flow back to the flow generation device. The test fish is located in the test tank and is blocked by the first fish gate and the second fish gate, and lives in the test area. The invention overcomes the problem that there is no accurate data of fish suitability and preference in the construction of the fish shelter environment of the original waterway project. It has the characteristics of simple structure, observing the life rules and preferences of fish to determine the suitable living environment, providing basic data and guidance for the construction of fish shelters in waterway projects, and simple and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of fish behavior, and relates to a water tank and a method for testing the habitat suitability of a fish shelter in waterway engineering. Background technique [0002] Waterway transportation is an important part of China's strategy to strengthen my country's transportation, and the construction of waterway projects such as waterway construction, dredging, and renovation is a necessary guarantee for maintaining smooth waterway transportation. However, during the construction of various waterway projects, the suspended solids, shock waves, underwater vibration and noise caused by blasting, sand dredging, piling and other construction operations will affect the normal activities and even survival of fish and other aquatic organisms in the corresponding waters. rate has a significant impact. Therefore, choosing suitable unshaded waters near the river section of the waterway engineering construction to create s...
