| Abstract: | The body attack angle of common bream Abramis brama varied with swimming speed and was best described by θ = ?3·32 (±0·24) ? 9·23 (±0·54)e? u ( r 2 = 0·56, P < 0·0001; ±1 s . e . given in parentheses), where θ is the body attack angle and u is swimming speed. The hypothesis that neutrally buoyant fishes may swim with body attack angles deviating increasingly from 0° as the swimming speed decreases is supported. |
