Abstract
A device for measuring the feeding behavior and the community relation of small fishes relates to a device used by the fish behavior ecology research. The device comprises a cross bar, a hook, fluorescent lamps, a glass jar, a copper ring, a hopper, a coverless glass culture dish, black plastic boards, a camera, a data transmission line, a display, a display transmission line and a computer host and is characterized in that the height of the glass jar is 1.0 meter; the bottom of the glass jar is a square with the side length of 0.5 meter; the coverless glass culture dish is placed in the center at the bottom of the glass jar; the fluorescent lamps are placed at the tops on two sides of the wall of the glass jar; the cross bar is placed at the top of the glass jar; the hopper is fixed in the center of the cross bar above the glass jar by the copper ring; the camera is hung on the cross bar by the hook and is connected to the computer host through the data transmission line; the periphery of the glass jar is wrapped by four black plastic boards; the top of the glass jar is sealed by one black plastic board; and a circular port is formed in the center at the top of the glass jar and is used for the hopper to be embedded into.
Description
Technical field
The utility model relates to the device that uses in the fish feeding behaviour ecological study, particularly relates to the device of using in the research of a kind of feeding behaviour of small fishes and community grade tagmeme.
Background technology
The focus of present international research was not only in the research of grade of fit before the artificial domestication fish were released, and for the specification of releasing, the quantity of releasing of raising and train fish, release the season and the place of releasing etc. choose reasonable with determine to provide scientific basis.The competitiveness of ingesting is and the closely-related phenotypic characteristic of grade of fit, obtains the ingest the most direct environment of relevant data of competitiveness of fish and comes from natural water.But complicated and changeable because of habitat in the natural water, therefore the sampling difficulty should not design related experiment in the open air and also accurately measure, and can only depend on the lab simulation natural environment and take proper method to measure indirectly.More existing utilize the order of ingesting individual in the mensuration group, the grade of ingesting of measuring salmonid, flatfish and Lun Shi Tilapia mossambica individual in population is indirectly determined the community grade tagmeme between individuality in the fish colony, thus definite its competitiveness.But said determination institute operative installations does not all adopt effective anti-interference method, this accurate measurement for fish community hierarchical relationship has produced adverse effect, and these mensuration all lack unified standard, need develop different experimental provisions at the fish of different builds, different size.By grasping the feature of small fishes feeding behaviour and community relation, can be artificial releasing's effect that assessment raises and train fish scientific basis is provided, also provide scientific basis for formulating the scientific and effective Technique in Fishes technical regulation of releasing of raising and train, help to improve the efficient of releasing, minimum human is released to the influence of indigenous fish.
The utility model content
The purpose of this utility model is to provide a kind of simple and easy to do device for the tagmeme grade of ingesting of measuring the small body type fish.
The technical solution of the utility model is by cross bar, hook, fluorescent lamp, glass jar, copper ring, funnel, the uncovered glass culture dish, the black plastic plate, camera, data line, display, show transmission line, host computer is formed, it is characterized in that the glass jar height is 1.0 meters, the bottom is the square of 0.5 meter of the length of side, the uncovered glass culture dish is placed on the glass jar bottom center, fluorescent lamp is placed at top, glass casing wall both sides, cross bar is placed on the glass jar top, a funnel is fixed on glass jar top cross bar central authorities with copper ring, camera hangs on the cross bar by hook, and camera is connected to host computer by data line; Be wrapped in around the glass jar with 4 blocks of black plastic plates, 1 block of black plastic plate is with the glass jar top seal, and its central authorities establish 1 round mouth and embed funnel.Camera can be taken ingesting of whole glass jar Mesichthyes and motion conditions, and the image of shooting is presented on the computer monitor in real time, and display is connected with host computer by the video data line, so that observe and record.
Advantage of the present utility model is that assay device structures is simple, and the sealing height is easily manufactured, is easy to promote; The utility model utilizes full-closed structure to eliminate and disturbs, measurement result is with the feeding behaviour and the community hierarchical relationship of digital form reflection small fishes, easy and simple to handle feasible, measurement result is accurate, provide scientific basis for formulating the scientific and effective Technique in Fishes technical regulation of releasing of raising and train, help to improve the efficient of releasing, minimum human is released to the influence of indigenous fish.
Description of drawings
What accompanying drawing was represented is the determinator schematic diagram of a kind of small fishes feeding behaviour and community relation.
Embodiment
The utility model (referring to accompanying drawing) is made up of cross bar 1, hook 2, fluorescent lamp 3, glass jar 4, copper ring 5, funnel 8, uncovered glass culture dish 7, black plastic plate 6, camera 9, data line 10, display 11, demonstration transmission line 12, host computer 13.Glass jar 4 highly is 1.0 meters, and the bottom is a square, and the length of side is 0.5 meter.Glass jar 4 bottom center are placed 1 uncovered glass culture dish 7 as ingesting the district, and its uncovered glass culture dish 7 diameters are 12 centimetres.Glass casing wall both sides far from the top 30 centimeters fix 2 fluorescent lamps 3 in order to simulating nature light, fluorescent lamp 3 power are 8 watts T5 fluorescent lamp, its length is 0.3 meter.A cross bar 1 is placed at the glass jar top, and a funnel 8 is fixed as bait thrower with copper ring by cross bar central authorities above glass jar, and the bore of its funnel 8 is 15 centimetres, and funnel all can fall into the district of ingesting exactly as bait thrower institute bait throwing in material.Camera 9 hangs on the cross bar 1 by linking up with 2, is connected to host computer 13 by data line 10.For making in the experiment light evenly and avoid artificial disturbance, will wrap up around the glass jar 4 with 4 blocks of black plastic plates 6.Be 0.5 meter black plastic plate with the glass jar top seal with 1 length and width, its central authorities establish 1 circular open and place funnel 8.Camera 9 can be taken ingesting of whole glass jar Mesichthyes and motion conditions, and the image of shooting is presented on the computer monitor in real time, and display 11 is by showing that transmission line 12 is connected with host computer 13, so that observe and record.When the community grade tagmeme of mensuration small fishes concerns, ready water is poured in the glass jar into 0.5 meter of the depth of water earlier.Connect camera and computer, the image that camera is taken appears on the display.Then that 2 tails sizes is identical but small fishes of the same race that genetic background is different (as, 1 tail is wild juvenile fish, 1 tail is the juvenile fish of artificial propagation) put into water tank, spend 10 minutes after, the fish group activity is stable.Utilize funnel with agreeable to the taste pellet by throwing into the district of ingesting, open recording function this moment, writes down after this ingesting of the shoal of fish and compete and active situation.
