摘要

This study was conducted to determine the endurance of lake whitefish (Coregonus clupeaformis) larvae swimming at various speeds to provide a basis for evaluating their potential for entrainment at municipal and industrial water intakes. Swimming endurance was determined by exposing a larva to water velocities of 5, 7, or 9 cm/sec for 30 min in an artificial flume. The results of this study indicate that swimming endurance slowly improves with age, suggesting that younger larvae would be vulnerable to entrainment at lower intake velocities than would older larvae. The data presented in this report can be used in estimating the entrainment vulnerability of whitefish larvae at existing or proposed water intakes in the Great Lakes.
