Abstract

The invention discloses a variable-slope water tank for coastal zone fishway tests, and belongs to the field of fish behavioristics test research. The variable-slope water tank comprises an energy dissipation water tank, a wave pushing device and a water tank device. The wave pushing device is installed on the energy dissipation water tank, and the water tank device is installed at the tail end ofthe energy dissipation water tank. The variable-slope water tank has the advantages that: 1, energy dissipation can be completed in a small area; 2, a stable complete standing wave with the wavelength range of 0.2-1.2 m can be obtained; 3, a water tank is convenient to install, and the vertical angle of a side wall can be accurately adjusted; 4, due to the fact that the side wall of the water tank is accurate and vertical, the power of a wave pushing motor is only 300w; and 5, the behavior test of the fish under the wave-current interaction effect can be conveniently carried out.

Description

technical field [0001] The invention relates to a test water tank, in particular to a variable-slope water tank used for fishway tests in coastal zones, and belongs to the field of fish behavior test research. Background technique [0002] Many fish behavior studies in the prior art are carried out through water tanks, but the existing water tanks often cannot meet the needs of fish behavior research. Especially river and sea migratory fish. Their behavior tends to vary greatly in coastal zones where the brackish water meets fresh water. And these behaviors, especially swimming, are heavily influenced by tides and waves in the coastal zone. [0003] Tidal barriers along the coast block the migration paths of many fish species. Therefore, it is a very important engineering measure to build a fishway on the tide lock. The fishway at the tide lock will inevitably be affected by waves and tides. [0004] Therefore, there is no relevant research on the behavior of fish when ...
