Abstract : The report analyzes the physical forces acting on fish swimming in bowls at the end of an arm of a centrifuge. From these analyses, the corrective forces of the fish are determined and their magnitudes and directions are evaluated. Under the experimental conditions, the horizontal semicircular canals play no effective part in fish orientation. The other pairs of canals are moderately or extremely important. (Author)
