Tester for acousto-optic-electric action of fishes

Abstract

The invention relates to a fish acoustic-photoelectric behavior testing device, comprising an acoustic reaction device, an optical reaction device and an electric reaction device which are independently combined with a circulation water trough to assemble the testing device or combined with each other two by two and then combined with the circulation water trough to assemble a fish behavior testing device or combined together and then combined with the circulation water trough to assemble the fish behavior testing device; the water flows through a plurality of pores on a water outlet device of the circulation water trough, thus leading the circulated water flow inside the trough body to have stable flowing speed; furthermore, high-precision filtration is adopted to lead the water to have high cleanliness, so as to adapt to the long-time fish behavior test. The fish acoustic-photoelectric behavior testing device has the advantages of reasonable structure, easy fabrication, and especially has the beneficial effects of easy controlling the testing acoustic source to simulate various fish sounds, easy changing the colors of testing light, providing various external profile of penetrating light, controllable electric reaction test voltage, easy measuring the test reaction region, carrying out the long-term fish behavior testing, etc.

Description

technical field [0001] The invention relates to a fish behavior research test device, in particular to a fish acousto-optical behavior test device. Background technique [0002] With the continuous development of modern science and technology and the need for further development and utilization of pelagic fish resources, there have been some new developments in net-free fishing technology both at home and abroad; new technologies (mainly including sound, light and electricity) have begun to be directly applied to Fishing production marks that human beings have entered a new stage in fishing production activities where they can control fish movements for fishing, especially the rise of netless fishing technology, which has become a new symbol of the modernization of fishing technology. Therefore, the operation method of the combined application of various new technologies such as sound, light, electricity, etc. is also being tested and studied. [0003] Acoustic fishing is a...

Problems solved by technology

For the traditional test device, it has the following limitations: the control of the fish acoustic response test is relatively simple, the types of simulated sounds are not rich enough, and the control of the simulated sounds in the test is not flexible enough to meet the needs of various fish and fish. Responses to different sounds at different stages need to be studied; there is a lack of real-time changes to the outline and color of the light irradiating fish in the test, and it is difficult to measure the reaction area of ​​different fish to various visible lights in traditional test equipment. ; Lack of controllability of voltage, lack of regional test measurability of fish's response to different voltages; the limitations mentioned above make it difficult to carry out more in-depth research on traditional test devices, and at the same time because of the poor filtration accuracy of fish behavior tests The limitations of high and stable current performance are not enough, and it is not easy to conduct long-term electrical reaction behavior tests, which cannot meet the test requirements of these modern technology researches.
