Description
Technical field
The utility model belongs to the experimental facilities technical field, relates to a kind of fish experimental provision, is specifically related to a kind of fish visual experiment device.
Background technology
Result of study shows that concerning most of fish, vision is most important sensory function, is the key factor that influences the fish behavior to the stimulation of fish vision.In the fish production operation, we need understand fish can see what, can distinguish color, operating water depth place at fishing gear, under the very low situation of light illumination, the visual sensitivity of fish and to the resolution capability of object, and whether fish have the memory capability of vision, vision is to influence of fish cluster or the like.These all are the design considerations of Fishing Gear and Fishing Method, are the important evidence that improves catching rate or carry out selective fishing.About the achievement in research of the visual capacities of fish to the raising of the development of fishery science, productivity ratio and preserve the ecological environment and resource all significant.
River the design of Japan device measure fish to the various reaction experiments that coloured light is arranged: in a circular channels, the center is provided with circular space, the annulus that constitutes with tank radially is divided into 8 cells, between each cell and the central, circular tank passage is arranged.Each cell throws light on separately, and can control light color in the cell by inserting various colour filters.Intensity of illumination in the cell is 50lx, 8 kinds of colors such as that colour filter has is white, red, orange, pale purple, green, blue or green, blue, purple.Place the experiment fish in the central, circular tank after, observed and recorded experiment fish enters the number of times of each cell, and then gives statistical analysis, however this apparatus structure complexity, and attainable color is unfavorable for the fish vision is carried out omnibearing experiment very little.
Recently, external also have the researcher attempting using such experimental technique: in a bigger fish jar, the space that can move about is provided for fish, the light source output of a series of existing arrangements is arranged on the casing wall, export orderly and a linearly moving visual stimulus are provided by controlling light source on the wall, be thereby influence the fish parade.Researcher's purpose is to improve the benefit of commercial fish culture, promptly wish to significantly improve the individual growth speed of fish by the best trip speed of control fish, this be because consider " benefit that static macrura reevesii can not get moving about; and the macrura reevesii that excessively moves about has consumed too much energy; but this device can not accurately be controlled light source output, can't carry out the experiment that persists of fish vision.
Summary of the invention
Technical problem to be solved in the utility model is existing fish visual experiment apparatus structure complexity, the incomplete problem of experiential function, and provide a kind of fish visual experiment device to address this problem.
The utility model solves this technical problem by following scheme:
A kind of fish visual experiment device, comprise fish jar, some light sources, described some light sources are arranged on the fish jar wall inner surface, it is characterized in that this device also comprises the single-chip microcomputer that is used to control some light-source brightness, light on and off time ratio and light source luminescent color, each light source all is connected with an independent triode as light source switch, and described single-chip microcomputer is electrically connected with some light sources by triode.
After adopting this structure, whole experiment device only comprises fish jar, be arranged on the some light sources on the fish jar wall inner surface, and be used to control some light-source brightness, the single-chip microcomputer of light on and off time ratio and light source luminescent color, simple in structure, during experiment, in fish jar, put into some fishes, open single-chip microcomputer, the light source that is arranged on the fish jar wall inner surface can carry out visual stimulation to fish according to the instruction of single-chip microcomputer, and is simple to operate, and because this operation is to carry out on away from the single-chip microcomputer of fish jar, therefore, the operator can't cause interference to the behavior of fish, guarantees the science of experimental result.
On the other hand, the vision of fish has an outstanding feature, the time that persists that is it is very short, may be several microseconds, the utility model adopts the switch of triode as light source for this reason, the transition frequency that triode is suitable can guarantee the of short duration control (just should be consistent with the retentivity time of eye of fish) of light source light on and off time, and the ethological observation of fish is often needed the long time, vision specific to fish is like this equally, whole experiment device will work long hours, have only the suitable current ability to bear just can assurance device failure-free operation, in view of above consideration, triode described in the utility model be a 2sc2655 type triode, this triode not only high frequency performance is good, and can bear bigger electric current, and it is 2A that the maximum of described triode is born electric current, transition frequency is 100MHz.
Before the utility model, the illumination of light source is also inhomogeneous, also can have light leakage phenomena between adjacent two light sources simultaneously, and these cause interference all can for the vision of fish, cause error to result of experiment.At this problem, each light source described in the utility model includes backlight, and make by the reflective membrane at the LCD back side described backlight plate face and side.
Can send the light of different colours for the light source of realizing fish visual experiment device described in the utility model, all be provided with the Light-Emitting Diode of reddish yellow blue three-color on each light source, control principle is that single-chip microcomputer is realized the proportioning of three primary colours by the brightness (promptly controlling the voltage swing of each light emitting diode) of controlling reddish yellow blue three-color light emitting diode in the light source, thereby produces different colors.
