Embodiment 1

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The invention discloses a method for testing the swimming speed of a fish, comprising: a fish swimming test device, a test section arrangement of the fish swimming test device, a test process of a fish swimming speed, and statistics of test data.

[0024] Described fish swimming test device comprises (see figure 1 ): Outer water tank 1, ring road 2, test section 3, propeller 4, variable frequency motor 5, said ring road 2 is set inside the outer water tank 1, test section 3 takes a straight section on the ring road 2, and propeller 4 goes deep The circuit 2 is driven by a variable frequency motor 5 to push the water body in the circuit 2 to move.

[0025] The test section arrangement of described fish swimming test device refers to (see figure 2 ): In the habitat of the test fish species, pebbles are selected to lay on the test sect...

Abstract

The invention discloses a testing method for onrush swimming speed of fishes. The method comprises the following steps: arranging a fish swimming testing device; arranging a testing section of the fish swimming testing device; testing the onrush swimming speed of the fishes; counting test data. The invention particularly discloses a method for testing the swimming speed of the fishes adopted in an ecological fishway establishment process, and belongs to the field of ecological environment protection testing in water conservancy projects. According to the testing method for the onrush swimming speed of the fishes provided by the invention, the problem of testing of the onrush swimming speed of echeneis naucrates is solved; the speed tested by the method can help the echeneis naucrates to pass through an ecological fishway after being adopted in the design of the ecological fishway.

Description

technical field [0001] The invention relates to a method for testing the swimming speed of fish, in particular to a method for testing the swimming speed of fish used in the construction of an ecological fishway, and belongs to the field of ecological environment protection experiments in water conservancy projects. Background technique [0002] The rush swimming speed is the maximum speed that the fish can reach, and the maintenance time is very short, usually <20s. At this speed, fish obtain greater energy through anaerobic metabolism, obtain a short-term explosive speed, and also accumulate waste such as lactic acid. According to the different swimming time, burst swimming ability can be divided into burst swimming speed and burst swimming speed. Among them, burst swimming speed refers to the maximum swimming speed reached by fish in a very short time (<2s), which is usually used in predation and emergency avoidance. Breakthrough swimming speed refers to the maxim...
