Description
Technical Field
The utility model relates to a test equipment technical field especially relates to an aquatic animal habitat selects to shoot with video-corder test device.
Background
The fish ethology is a subject for researching the interaction problem of fish to the environment and other organisms, and has important guiding significance for fish resource protection, fishery culture production and the like. The fish preference behavior is an effective index for measuring the selection and preference degree of different thresholds of the fish on the environmental factors, and is an important content in the research of natural habitat protection, fish passing facility design, welfare culture and the like of the fish. Environmental factors such as illumination and substrate are conventional contents in fish behavior preference research. The fish preferential behavior research is obtained based on parameters such as distribution frequency, active time, speed and distance of fish in various environmental factors. The habitat selective videography test is an important test for studying aquatic animals.
In the existing habitat selection shooting and recording test equipment, the phenomenon that the movement track of an animal is shielded by a partition plate often occurs, so that the test process is complicated, and the labor cost is increased. In the existing shooting and recording test for selecting the illumination habitat, a waterproof point light source is mostly adopted for an underwater illumination test, the test cost is also higher, the waterproof point light source cannot form a uniform light field, the underwater illumination intensity is uneven, and the inaccurate test result caused by the fact that the light color or the light intensity of the fish illumination habitat selection cannot be analyzed is caused.
The light irradiation and substrate preference behavior research is generally carried out by a hydrostatic test method or a flow rate selection similar loop. By adopting the still water test method, due to the lack of swimming behavior induction, the fishes are likely to stay in place and do not move or move, but the movement does not exceed the boundary of the environmental factors, so that the preference behavior cannot be truly reflected, and test errors or conclusion errors are caused. By adopting the loop test method, a flow velocity gradient distribution mode with uniform transverse flow velocity and different longitudinal flow velocities can be formed, so that the behavior interference of fishes can be generated due to the flow restriction energy in the test process, and the test result is not strong in persuasion. In addition, fluctuation of the water surface can be caused in most of flowing water tests, and image interference occurs when behavior fine analysis is carried out by software in the later period.
In the video acquisition process of fish behaviors, the situation that the movement track of fishes is shielded by a baffle plate in a test area often occurs, so that test errors are generated during software tracking. The manual correction is needed for each test, a large amount of manpower and time are consumed, and the test progress is influenced.
In addition, when environmental factors such as dissolved oxygen, flow velocity and the like are collected in related experiments, because the test device is not separated from a collection area, the track tracking of aquatic animals is influenced by the existence of equipment in real-time monitoring, and therefore the existing experiments mostly adopt a mode of collection after the experiments. Besides not being able to monitor the water environment in real time, it also can change the animal's movement behavior.
