Radio-instrumented sea otters (N = 45) that were released into eastern Prince William Sound during summer, 1989, following efforts to rehabilitate them at otter treatment centers, have been monitored regularly for approximately 2 years. Respective survival rates of male and female sea otters released from the treatment centers were: Year 1: males P = 0,401, females P = 0.401, females P = 0.445; Year 2: males P = 0.714, females P = 0.692. Only 2 of 11 (18%) mature females pupped during 1990. Sea otters released from treatment centers had lower survivorship and pupping rates than sea otters in other study populations.
