Ein Elektronisches Funktionsmodell für Verhaltensweisen eines Fisches

This paper is concerned with a model for the interaction of certain behaviour patterns of a fish (Pelmatochromis subocellatus kribensis BOUL; Cichlidae). Five behaviour patterns (schooling behaviour, locomotion, biting, fleeing, camouflaging) are described as a function of four external stimulus patterns (CO₂-concentration, school-signal, conspecific's signal, frightening-signal) and three so-called internal states of readiness (readiness to school, readiness to attack with bites, responsiveness to frightening stimuli). In accordance with the statistical appearance of behaviour patterns the model contains five interdependent statistical pulse generators. This model is planned to find and to confirm a theory for a quantitative description of behaviour patterns, the interdependencies of which give a representation of the internal structure of the organism.
