Outline of Final Research Achievements

We investigated schooling behavior of the tropical non-electrogenic transparent catfish, glass catfish, and their swimming behavior under sinusoidal electrical stimulation. The schooling behavior was analyzed by a custom made software. We inferred the separation distance between fish from their schooling behavior. In the swimming behavior experiments, glass catfish avoided the sinusoidal electrical stimulation in a low frequency range. We also investigated spiking patterns of electroreceptors of glass catfish in response to the sinusoidal electrical stimulation and revealed its nonlinear characteristics. Non-periodic bursting electrical activity of nerve impulses were associated with the avoidance behavior. Further, the nonlinear property of spiking patterns were reproduced by an analog electric circuit.
