The oscillation in each of 17 locomotor variables of 8 different active goldfish is studied by time series analyses. The fish had been monitored singly for over 15 hrs on different dates over a 2-yr period and under controlled conditions of temperature, light, water quality, and flow. The derived autoregressive models reject the “random”; hypothesis of independent observations over time. Instead, the correlo-grams oscillate smoothly and regions of positive and of negative partial serial correlation are apparent. Prediction of future behavior of the series is greatly enhanced by the models, and distinct patterns in their coefficients are evident for individual fish over all variables and individual variables over all fish. Angle size relationships are the most rigid oscillators. Mean step length is the most pliant variable and hence is the most likely parameter to be modulated by the control mechanism or mechanisms of orientation. The authors surmise that the 17 variables, with their varying periodicity, strength, and frequency of oscillation, have a complex multivariate interrelationship which establishes the constraints within which locomotor behavior is bounded. The above analytical approach seems to lend itself to the construction of a cybernetic model of hierarchal control of locomotion in fish. |
