Эффективность акустического метода управления поведением рыб и факторы, влияющие на нее

The acoustic method is an effective way of controlling the feeding behavior of fish; its improvement required a series of experiments. In the studies described, the acoustic signal of an electromagnetic emitter is used as a conditional stimulus in the formation of the conditioned-reflex behavior of fish. Research is being conducted in the Tver Region, on waters of Vazuzskiy reservoir, near Zubtsovskiy pond fishery, for five years. Present study of 2018 aims the separation of the artificial acoustic stimulus from other factors determining behavior of fish and assessment of its informational significance for fish. The complex of factors, affecting possibility and effectivity of the method usage is explored and systematized. Behavior features of the group of fish, trained to gather by the acoustic method are compared to ones of the control group, gathered only for feeding. It has been proven, that the sound-trained group could be gathered and relocated faster, then the fed one. Sound-trained fish behavior allows recognizing them among others. The results of experimental works shows that the acoustic signal of the “EME” (electromagnetic emitter) stimulator used within the method is a priority factor for the formation of a trained group. It is shown that the use of an acoustic method to control the behavior of fish allows you to create a group of fish that can be collected at selected points of water area with acceptable environmental conditions for this specie and move it up to a distance up to 280m in one passage. Adjusting the elements of this method of controlling the behavior of aquatic biological resources, based on the tasks and conditions of work, the characteristics of water bodies and target fish species, expands the possibilities of its application.
