Extract

Studies of stream bottoms as a factor in the abundance of aquatic insects is usually accomplished by random sampling of different kinds of pools and riffles. Various types of apparatus and methods are used. Ludwig (1922) used the hand-dip method in his studies. The Needham trap (1928) has also been used extensively in the study of rocky riffles. Gersbacher (1937) used the Peterson trap (1911) and the Ekman dredge (1911) for sand and mud bottom pools. At present the United States Bureau of Fisheries one foot trap, described by Surber (1937), is very popular in studying riffles.
