Abstract

Fish population studies initiated in 1953 indicated that most species were on the increase until the winter kill of 1955. In 1956, populations were below normal; in 1957 there was an increase in most species, followed by a decrease in 1958. Studies during 1953 and 1954 showed that the food of adult yellow bass consisted to a great extent of young-of-the-year yellow bass and gizzard shad, along- with insects. During the summers of 1956, 1957, and 1958, forage fish were of very minor importance in the diet of yellow bass; they fed mainly on immature insects and minute crustacea.
