摘要:
A hatchery release tank was designed which permitted the voluntary release of pink salmon (Oncorhynchus gorbuscha) fry. Fry release was stimulated by rising temperatures and increasing turbidity. Because even relatively immature fry left the tank under these conditions, fry were released only between 0800 and 1000 hr, when both temperature and turbidity were low. After entering the stream, hatchery-produced fry appeared to behave normally. They buried themselves during daytime and, within a few days, moved downstream during the night.
