| Abstract: | A series of stepped velocity tests were carried out in a Brett‐type swimming respirometer and the overall range in swimming performance for 12 Schizothoracinae species was measured. The relative critical swimming speed Ucrit and burst speed Uburst decreased with body length, while absolute Ucrit and Uburst increased with body length. Ucrit increased with temperature up to approximately 15° C and then decreased. Species with a high Ucrit also displayed a higher Uburst. |
