| Summary: | M.S. Thesis by Donald C. Hales, in partial fulfillment of the requirements for the degree of Master of Science in Wildlife Management, Utah State Agricultural College, 1955. Written under direction of Professor William F. Sigler. Typewritten, 40 single-sided pages, including 7 pages of mounted b&w photos. Includes tables and charts. The square-foot bottom sampler has been the principle instrument used for quantitative studies of the bottom fauna in riffle areas of streams. However little has been written concerning the actual number of square-foot samples necessary to describe stream bottom fauna in terms of the number or volume of organisms. The object of this study is to determine the minimum number of bottom samples that adequately describe the bottom at any time or location. The study areas are located in Logan River, Utah, and two of its tributaries: Temple Fork and Beaver Creek.
