Webb, P. W. (1983). Speed, acceleration and manoeuvrability of two teleost fishes. Journal of Experimental Biology. 102:115-122.
Speed, acceleration rate and turning radius were measured for rainbow trout (Salmo gairdneri; length 25 multiplied by 7 cm) and smallmouth bass (Micropterus dolomieu ; length 23 multiplied by 6 cm) attacking live minnows. The observations sampled a range of values for each kinematic variable up to the limits of maximum performance. Minimum turning radius was independent of speed and acceleration rate. Expressed as a ratio of total length, L, minimum radii were 0 multiplied by 18 plus or minus 0 multiplied by 2 L for trout and 0 multiplied by 11 plus or minus 0 multiplied by 02 L for bass (-X) plus or minus 2 S.E.). Differences in minimum turning radius, R, between trout and bass were attributed to differences in the volume of the body and entrained water, V, and projected lateral surface area of the body and median fins, A. For subcarangiform swimmers, the dimensionless minimum specific turning radius R/L = 2V/AL.
