Stochastische und rhythmische Eigenschaften spontan auftretender Verhaltensweisen von Fischen

A statistical model is presented exhibiting properties of time sequences of certain spontaneously occurring and mutually interdependent behavioural movements of a fish. The statistical description is derived from the theory of renewal processes. It is demonstrated that the probability of a movement to occur is a function only of the temporal distance to the movement that occurred immediately before. Models are developed which can be easily simulated by computer or built up in hardware technique.
