Abstract
The swimming performance of nine species of Southern California fish was tested in a flume at velocities of 42 to 117 cm/second. Genyonemus lineatus demonstrated the fastest continuous swimming ability of 61 cm/second, Hypsurus caryi the slowest, 42 cm/second. Five embiotocids tested demonstrated similar continuous swimming speeds ranging from 42 to 52 cm/second. Burst swimming abilities were in excess of 100 cm/second for four of five species tested; G. lineatus attained 137 cm/second. Chromis punctipinnis was the best swimmer relative to body length (BL), reaching 5.9 BL/second continuous and 11.1 BL/second burst swimming speeds. Gravid Hypsurus caryi had a lesser swimming ability than nongravid and male individuals of the species.
