Row result is far from reaching expected fish effect excessively.Fish effect, corresponding attracting measure research and development are crossed for increase fish pass structure
Also gradually carry out.Practice have shown that photo-induction fish measure have the effect of it is certain, due to fish exist to the behavior reaction of light it is certain
Difference, part fish have Phototactic behavior, such as saury pike, sand lance, black carp, and part fish, which then exist, is protected from light behavior, such as mud
Loach, sea eel, fresh water Nian etc., different fish are to the color of light, the fish of different larval instar, same fish in Various Seasonal to light also table
Reveal different behavior reactions, therefore there is also certain differences for the effect of attracting.To further promote the effect of photo-induction fish,
It needs the protection fish for section where power station or crosses fish target development mutually reply light behavior reaction research.
The existing device for being related to the test of light behavior reaction is often directed to individual fish and is designed, and device figure is smaller, cannot
Group fish are carried out to the behavior reaction of light；Not can be carried out different photochromic white lights when influencing test or test to Fish behavior it
Between exist interference；Test structure exists between each light area when cannot be used for illuminance to Fish behavior experimental study or test
Overlapping, interferes with each other, while testing and often not becoming area of light illumination to fish and suitable area of light illumination is studied；Structure is not tested also not
Can be carried out light source scintillation influences to study on Fish behavior.
Therefore, it is necessary to research and develop it is a kind of can be for fish individual or fish group into different photochromic, different illuminance and flashing
Test structure of the frequency to Fish behavior reaction test.

Main operational principle of the invention is as follows:
(1) when test prepares, start water pump, river water body is introduced in test dark place, adjust the lock in imitative nature storage pond, holding pond downstream
Door height, arranges barrier net, adjusts the water level of imitative nature storage pond, holding pond and light behavior reaction test section.Meet test to water level to want
When asking, pump house can be closed, stops diversion and enters test platform；If desired moving water state can not close pump house；If desired each light row
It is different for the flow rate environments of reaction test section, the adjusting of flow can be carried out by the branch pipe valve that becomes a mandarin of each test section.
(2) after water environment is set, the setting of luminous environment is carried out according to the concrete condition of test.With fish to photochromic
Behavior reaction test for, the lamp of each smooth behavior reaction test section is adjusted to the different colours that test needs, debugging is single
Other lamps are closed when a lamp, adjust lamp intensity and and at a distance from the water surface, with underwater irradiance meter to illumination center water body surface layer
Illumination measure, control surface layer maximal illumination in 10 luxs, then by each smooth behavior reaction test section hood
It is covered, only retained export is connected with imitative nature storage pond, holding pond.
(3) it after luminous environment is set, puts test fish into imitative nature storage pond, holding pond, closes light in test dark place, open
Thermal camera and infrared monitoring system start to test, and pass through thermal camera Observable test fish during test with after
Behavior reaction analyze test fish and enter each smooth behavior reaction test section by infrared monitoring system recorded data
Situation determines the photochromic of test fish hobby.
(4) after having carried out color test, can further progress fish to the behavior reaction testing experiment of illuminance.In light
When according to test, according to step (2), according to color test as a result, the hobby that all lamps are adjusted to test fish is photochromic, continue to adjust
All light source strengths are saved, make the illumination for being radiated at water surface surface layer central point in 1 ~ 100 lux, and be classified.To the ring of light
It after border is set, is tested according to step (3), determines the illumination conditions of test fish hobby.It is also possible to according to the knot of test
Fruit determines become area of light illumination and the suitable area of light illumination of test fish.
(5) after carrying out illumination test, also can further progress flicker frequency test.In flicker frequency test, press
According to step (2), according to illumination test result, the hobby that all lamps are adjusted to test fish is photochromic, adjusts all multi-colored led light
Source strength, makes the value for the illumination illumination test result for being radiated at water surface surface layer central point, and to the flicker frequency of each lamp into
Row setting, is changed by 0.1 ~ 25Hz.It after luminous environment is set, is tested according to step (3), determines the sudden strain of a muscle of test fish hobby
Bright frequency.It is also possible to have reaction range and reactionless range to optical flare frequency according to what the result of test determined test fish.
In fact, the imitative nature storage pond, holding pond in this test platform also can use the cross track and long rails of setting,
The position of lamp and video camera is set, to reduce the interference between light column, while guaranteeing that camera's range can cover entirely
Imitative nature storage pond, holding pond.
Structure space provided by the invention is sufficiently large, can accommodate the test fish that 10 individual body length are more than 30cm, can be into
Row group behavior test, and fish movement range is not limited by a space, and can avoid influence of the space scale to test result；Using
LED light makees light source, can carry out the parameters such as photochromic, intensity and flicker frequency by controller and be adjusted, different tests is arranged
Luminous environment；Light source can be shifted one's position by cross track or long rails, moreover it is possible to which it is centainly high that transformation height is such as laid in water surface
Degree or underwater certain depth change the illumination for being radiated at water surface light beam center to cooperate the intensity of light source to adjust；The present invention is by light
Source is placed in relative closure environment, and there is no interference between each photochromic, each light beam or the light of each flicker frequency, will not tie to test
Fruit impacts；Last structure of the invention can unrestricted choice river channels and hydrostatic condition, under river channels, settable difference
Flow rate of water flow condition, for Fish behavior observational study under the conditions of flow velocity and optical coupling, to analyze different fish, not of the same age
The primary-slave relation that phase, different condition flow velocity and light influence Fish behavior.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as limitation of the invention, this hair
Bright protection scope should be with the technical solution of claim record, technical characteristic in the technical solution recorded including claim
Equivalents are protection scope.Equivalent replacement i.e. within this range is improved, also within protection scope of the present invention.
