Estimates of fish populations from recapture of marked fish have, on several occasions, yielded estimates far below the population later shown to be present (Krumholz 1944, Carlander and Lewis 1948, Fredin 1950, Carlander 1952). Fredin (1950) suggested that the recapture of the fish by some method different from that used in the original capture might give less biased results. In the present investigation the bluegill population was estimated by the marking and recovery technique using seines and baited wire traps.
