Description
Technical field
The utility model belongs to the technical field of Fish behavior detection, more particularly to a kind of variable flow rate Fish Swimming Traces row
For observation device.
Background technology
Fish behavior is a new branch of science of researching fish Behavior law, belongs to the scope of Animal Behavior Science, with fish
Class ecology, physiology of fishes and fishery have extremely close relationship, and fish are under field conditions (factors) or under experiment condition
Various actions, including individual behavior and group behavior are all the research objects of Fish behavior.It is generally adopted in Fish behavior research
Fish behavior is monitored with traditional artificial observation procedure, this mode is more inconvenient, mostly qualitative record.
Invention content
The technical problem to be solved by the utility model is to provide a kind of variable flow rate Fish Swimming Traces measuring behavior device, energy
Enough automatic, quick, quantizations, the swimming behavior for intuitively observing fish, reduce manpower consumption, save time and cost.
Technical solution adopted by the utility model to solve its technical problems is provide a kind of variable flow rate Fish Swimming Traces row
For observation device, including fish jar, water pump, video camera, video frequency collection card and computer, the fish jar in three-stage connectivity structure,
Stage casing internal diameter is equal, both ends are tapered, and the both ends of the fish jar are connected to form cycle with water pump by water pipe, and the two of the fish jar
End is respectively equipped with grid, and the video camera setting is connect in the top of fish jar, the video camera with video frequency collection card, the video
Capture card is connect with computer.
The fish jar stage casing is cuboid, both ends are truncated rectangular pyramids shape.
Angle between the side and bottom surface of fish jar both ends truncated rectangular pyramids is 60 °~80 °.
It is provided at the top of the fish jar and puts lymphogranuloma inguinale.
The lymphogranuloma inguinale of putting is equipped with lid.
The water pump connect with computer and is controlled by computer and run.
Advantageous effect
The utility model controls the flow of fish bowl water by water pump, by the area of vertical cross-section in fish jar water (flow) direction
Variation influences, and the water velocity of different location is different, and target fish body selects specific according to itself habit in the case of water flowing
Flow position stop, by computer vision technique, can it is automatic, quickly, quantization, intuitively observed object Fish Swimming Traces row
For situation, it is possible to reduce time and cost are saved in the consumption of manpower, and the video image of acquisition can also further quantitative analysis fish

4 connection of card, video frequency collection card 4 can be acquired image information.Video frequency collection card 4 is connect with computer 5, by image information
Computer 5 is sent to be stored and processed.
The variable flow rate Fish Swimming Traces measuring behavior device controls the flow of water pump 2 by changing 2 voltage of water pump, by fish jar
The area change of vertical cross-section influences in 1 water (flow) direction, and water flow velocity is different, and rib is parallel at the point of side in truncated rectangular pyramids
The width of platform bottom is d cm, then the flow velocity of the position is 1000 × Q/ (d × d), and the flow velocity in cube is 1000 × Q/
400, wherein Q are the flow of water pump 2, and target fish body selects specific flow position according to itself habit in the case of water flowing
It stops, it, can automatic, quick, quantization, intuitively observed object Fish Swimming Traces behavioral aspect by computer vision technique.This
Sample can reduce the consumption of manpower, save time and cost, and the video image of acquisition can also further quantitative analysis fish row
For.
