Return Rates of Transported Steel head Smolts with and without a Rest Period before Release

Abstract

Abstract Postrelease smolt survival of summer steelhead Oncorhynchus mykiss that had been trucked 0.75 h and released was compared with that of smolts that had been trucked and allowed to rest for 24 h before release. Results showed no difference in return rates, suggesting that resting after transport may not improve steelhead survival.
