A creel census has been taken on Fife Lake, Michigan, for four successive fishing seasons, 1934 to 1937 inclusive. The data indicate a constant decline in the catch of some species and a corresponding increase in the catch of others. The total take remained relatively constant from year to year; an increase of 92 per cent in fishing effort resulted in an increase in the take of only 16 per cent. Some correlation was found between the percentage of larger piscivorous fish and the size of pan fish in the catch.
