Problems solved by technology

The swimming behavior of fish under still water conditions can be observed and analyzed by using a still water transparent tank (Reference 3), and the swimming behavior of fish under different motion states can be measured by using an annular circulating tank designed with different flow rates, but the actual activity area of ​​the experimental fish is limited to the tank When the flow velocity is too large, the experimental fish will be intercepted on the downstream fence, and its further behavioral response cannot be observed (Reference 4)
Since the above-mentioned experimental tanks are all open designs, the metabolic rate of the fish during the experiment cannot be measured

Embodiment Construction

[0022] Hereinafter, the present invention will be further described in detail with reference to the examples and drawings, but the implementation of the present invention is not limited thereto.

[0023] Such as figure 1 The shown fish activity metabolism and swimming behavior synchronization recording measurement device includes a cylindrical water tank 1 and an upper cover 2 made of transparent materials. A sealing ring 9 is arranged between the top of the water tank 1 and the upper cover 2 to form a closed water tank. There is a bubble discharge hole 6 in the middle of the cover. One side of the water tank 1 is connected with the water inlet pipe 3, and the other side is connected with the water outlet pipe 4, and the water inlet pipe 3 is provided with a flow regulating device 5. The flow rate adjustment device 5 can adjust the water intake to maintain the dissolved oxygen in the water body at a certain level. The upper side and the outer side of the water tank 1 are respecti...

Abstract

The invention relates to a device for synchronously recording the metabolism and swimming motion of fish, comprising a sealed water groove, which is connected with a water inlet tube and a water outlet tube, and a flux adjuster mounted on the water inlet tube. The water groove has annular water channel, and a water-flow generating adjusting device for controlling the water flow to flow along the annular water channel in one direction. The sealed water groove is made from transparent material. The camera device is mounted above / beside the sealed breath room. The invention can measure the basic or general metabolism, at different strengths, and record the swimming motion.

Description

Technical field [0001] The invention relates to a synchronous recording and measuring device for fish activity metabolism and swimming behavior. Background technique [0002] Metabolism is the most basic life activity of the animal body, and its metabolic intensity is closely related to the activity state and the amount of exercise. The measurement of metabolic rate is the basic method of metabolism research and an important means to evaluate the metabolic level and exercise intensity. Since fish live in aquatic environment, the determination of their metabolic rate generally adopts an indirect method of measuring the oxygen consumption rate in a sealed breathing room and then converting it into metabolic rate. The initial measurement is to place the experimental fish in a closed container (breathing chamber). The water in the container does not flow and does not exchange with the outside world. The metabolic rate per unit time is calculated by the difference between the dissolve...
