Northern pike and bluegill populations were established and maintained for 3 years in two small lakes closed to fishing. Growth of pike was slightly less than the average for pike in Michigan; growth of bluegills ranged from 3.6 to 7.4 cm (1.4 to 2.9 inches) below state average. High densities of pike (68 to 78 per hectare; 28 to 32 per acre) did not control an abundance of bluegills. Survival of pike from the initial stocking was extremely high (44–60%), whereas survival from subsequent plantings was low (0.8–9.2%).
