Abstract:

In a study of the Yellowstone cutthroat trout, Salmo clarki lewisi, by the US Fish and Wildlife Service, effects of environment on mortality of eggs, immature fish, spawners, and postspawners were measured for various components of the population in Yellowstone Lake. Five methods for estimating mortality of adults on spawning runs are described, with counting and tagging as the principal procedures. The white pelican is a serious predator on cutthroat trout in Yellowstone Lake.
