Abstract

The study of the Utah sculpin (Cottus bairdi semiscaber), or Rocky Mountain bullhead as it is known locally on Logan River, Utah, is primarily one of determining its relation to game fish. Field work for this study began in 1949 and continued to March of 1951. Numbers of the Utah sculpin on Logan River have been estimated to be as high as 150 per tenth mile of stream. The larger populations are in the area of the third impoundment on Logan River and downstream.
