Description
Technical field
The utility model belongs to biological study field, the exposure experiments to light device of especially a kind of fish.
Background technology
Fish behavior is subject to the impact of multiple biology and abiotic factor, comprises kind, developmental stage, circadian rhythm, veil, water velocity and illumination etc., and wherein illumination is a more crucial influence factor.Reaction according to fish to different illumination intensity, is divided into photopositive, negative phototaxis and without phototaxis.The become light rate of same fish under different illumination can be different, and for example Poecilia juvenile fish becomes when light illumination increases, and the meeting of light rate is obvious rises, and still, when intensity of illumination reaches after 2000lx, the light rate that becomes starts to reduce.Same fish also has different phototactic characteristics at different developmental stages, for example, along with the growing of mandarin fish, can be transferred to low light level district by highlights to the phototaxis of intensity of illumination.In addition, the fish of different kinds is to the selection of the illumination color also property of there are differences, such as nineteen fifty scholar is by 12 kinds of fishes such as stone porgy, common eel are found the taxis research of illumination color, and stone porgy preference is selected blueness and green light source, and common eel preference is selected red light source.Except the factors of influence such as intensity of illumination, illumination color, flash of light also can exert an influence to the taxis of fish.Therefore illumination, as a kind of ecological factor, has many-sided Ecology Action to fish, directly or indirectly affects the various actions activity of fish.
Behavior response by researching fish to illumination, can be applied in and lead on facilities for fish's passage and fish pass structure, the fish pass designing for inducing fish to enter, thus avoid being entrainmented or be detained and cut off migration passage.In addition, the response by researching fish to illumination, can also be applied in the fishing for of fish, and is convenient to quick nondestructive and fishes for.Therefore the exposure experiments to light of carrying out fish is very significant, mainly comprise optimal light intensity, optical wavelength etc., current experimental rig once can only be tested a kind of light intensity or a kind of optical wavelength, test period can be elongated like this, be unfavorable for control variables, therefore invent and a kind ofly can once test the light intensity of multiple gradient or once test the device of multiple illumination color, be conducive to carrying out fast and saving a large amount of manpower and materials of test.
Summary of the invention
Technical problem to be solved in the utility model is to provide the exposure experiments to light device of a kind of fish, can solve the problem that existing apparatus cannot once be tested the light intensity of multiple gradient or once test multiple illumination color, making full use of on the basis of all kinds of shape water tanks, obtain quickly and easily the suitableeest light intensity of different types of fish and preference optical wavelength, greatly save test period.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the exposure experiments to light device of a kind of fish, comprise test water tank, in test water tank, space, both sides is become multiple modules space by the light tight barrier partitions of polylith band specific light source, on test water tank, telescoping shoring column is installed, top is provided with camera, and in test water tank, central space is placed with liftable test net cage.
The length of each light tight baffle plate is identical.
Specific light source is the light source of varying strength or the light source of transmitting different wave length.
In liftable test net cage, halliard one end by coupler body be positioned over the test net cage of testing central space in water tank and be connected, the halliard other end is walked around at assembly pulley.
Test net cage is bottomless net cage.
Light tight baffle plate is arranged in test water tank by the draw-in groove in test water tank.
The shape of test water tank is not limited to square, can be also circular or other symmetrical structures.
The exposure experiments to light device of the fish that the utility model provides, become multiple modules space by the light tight barrier partitions of polylith, in modules space, provide different intensity of illumination or illumination wavelength by specific light source, discharge after the target fish in liftable test net cage, make its light intensity of freely selecting hobby or the optical wavelength of hobby, observe also log and complete test, can once test multiple intensities of illumination of Same Wavelength, or the multiple wavelength under same intensity of illumination are tested, can solve the problem that existing apparatus cannot once be tested the light intensity of multiple gradient or once test multiple illumination color, obtain quickly and easily the suitableeest light intensity of different types of fish and preference optical wavelength, save experimental period, simple in structure, easy and simple to handle, energy rapid-assembling, be conducive to save a large amount of manpower and materials, test net cage adopts liftable design, has realized artificial far distance controlled, avoids to a certain extent artificial disturbance, has guaranteed the accuracy of result of the test.
