Umatilla Hatchery Monitoring and Evaluation, 1995-1996 Annual Report.
- Oregon Department of Fish and Wildlife, Portland, OR
This report summarizes the monitoring and evaluation studies of salmonids reared at Umatilla Hatchery for the period November 1, 1995 to October 31, 1996. Studies at Umatilla Hatchery are designed to evaluate rearing of chinook salmon and steelhead in Michigan raceways. Characteristics of Michigan raceways include high fish densities, rapid water turnover, oxygen supplementation, reuse of water, and baffles designed to reduce cleaning. Fish health at Umatilla Hatchery and other facilities associated with the Umatilla program is intensively monitored and evaluated as part of the overall research project. Further, under the Integrated Hatchery Operations Team guidelines, specific requirements for fish health monitoring are mandatory and have become the responsibility of the fish health staff conducting the studies at Umatilla Hatchery. Additional studies include evaluations of sport fisheries in the Umatilla River and mass marking and straying of fall chinook salmon. Juvenile rearing experiments have been completed for subyearling fall chinook salmon reared in Michigan and Oregon raceways. Although preliminary adult return data has been recovered, the most data on post-release survival is incomplete. Conclusions in this report should be viewed as preliminary and used in conjunction with additional information as it becomes available.
