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

[0023] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0024] Fish activity metabolism and swimming behavior synchronous recording measuring device as shown in Figure 1, comprise cylindrical tank 1, loam cake 2 that are made of transparent material, there is sealing ring 9 to form airtight between the tank 1 top and loam cake 2 The water tank has an air bubble discharge hole 6 in the middle part of the upper 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 flow regulating device 5 is arranged on the water inlet pipe 3 . The water intake can be adjusted through the flow regulating device 5, and the dissolved oxygen in the water body in the device can be kept at a certain level. Cameras 8 are respectively provided on the upper...

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