Abstract

Controlled laboratory experiments indicate that postlarvae of Paralichthys lethostigma exhibit nonrandom withdrawal from water of low oxygen concentrations when values fall below 3.7 ml/l. Although flounder activity increases at higher temperatures (25.3°C), probit analysis indicates no differences in sensitivity to oxygen depletion at temperatures of 6.1°C, 14.4°C, and 25.3°C.
