Book Description
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.

Book Description
This report summarizes monitoring and evaluation studies of salmonids reared at Umatilla Fish Hatchery (UFH) for the period November 1, 1997 to October 31, 1998. 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 UFH and other facilities associated with the Umatilla program are 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 studies at UFH. Additional studies include evaluations of sport fisheries in the Umatilla River and mass marking and straying of fall chinook salmon. Except for adult recovery data, an experiment designed to evaluate rearing subyearling fall chinook salmon in Michigan and Oregon raceways has been completed. We are currently in the second year of rearing subyearling fall chinook salmon at three densities. Experimental rearing of subyearling, fall release, and yearling spring chinook salmon, and steelhead has also been conducted. Although preliminary adult return data has been recovered, data on smolt-to-adult survival for all groups is incomplete. Conclusions in this report should be viewed as preliminary and used in conjunction with additional data as it becomes available.

Book Description
REPORT A: UMATILLA HATCHERY MONITORING AND EVALUATION--This report summarizes monitoring and evaluation studies of salmonids reared at Umatilla Fish Hatchery (UFH) for 1 November, 1999 to 31 October, 2002. Studies at UFH 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 UFH and other facilities associated with the Umatilla program are intensively monitored and evaluated along with the overall research project. Further, under the Integrated Hatchery Operations Team guidelines, specific requirements for fish health monitoring at UFH are mandatory. An experiment designed to evaluate rearing subyearling fall chinook salmon in Michigan and Oregon raceways has been completed. An evaluation of survival of subyearling fall chinook salmon reared at three densities will be completed with final returns in 2005. Two new evaluations were started during this reporting period. The first is an evaluation of spring chinook survival of groups transferred to Imeques acclimation facility in the fall, overwinter-acclimated and released with the standard acclimated production groups in March. The second is an evaluation of subyearling fall chinook survival and straying of a direct-stream released group in the lower Umatilla River and the standard group acclimated at Thornhollow acclimation facility in the upper Umatilla River. An important aspect of the project is evaluation of the spring chinook and summer steelhead fisheries in the upper and lower Umatilla River. REPORT B: Fish Health Monitoring and Evaluation, 2000 Fiscal Year--The results presented in this report are from the ninth year of Fish Health Monitoring and Evaluation in the Umatilla Hatchery program. Broodstock monitoring for hatchery production was conducted on adult returns to the Umatilla River at Three Mile Dam and South Fork Walla Walla adult facilities for salmon; steelhead adults were monitored at Minthorn adult facility. A new addition to this year's report is the effort to bring together an overview of fish health monitoring results including historical and year to date pathogen information. This information is in table form (Appendix Tables A-28, A-29 and A-30). A summary of juvenile disease outbreaks at Umatilla Hatchery is also included (Appendix Table A-31). REPORT C: Fish Health Monitoring and Evaluation, 2001 Fiscal Year--Results from the 2001 annual report cover the 10th year of Fish Health Monitoring in the Umatilla Hatchery program. Efforts were again made to provide up to date fish health and juvenile disease outbreak loss summary tables from the beginning of the Umatilla Hatchery program (Appendix Tables A-27, A-28, A-29 and A-30). Outmigrant Fish Health Monitoring results were included in this report since this was part of the fish health work statement for this report period. The discussion section for the 2001 and 2002 annual reports are combined in the 2002 report due to time constraints and consolidation efforts to complete this report by the end of May 2003.

Book Description
The collapse of many of the World’s fisheries continues to be of major concern and the enhancement of fish stocks through techniques such as ranching is of huge importance and interest across the globe. This important book, which contains fully peer reviewed and carefully edited papers from the 2nd International Symposium in Stock Enhancement and Sea Ranching is broadly divided into sections covering the following areas: The present situation of stock enhancement Seed quality and techniques for effective stocking Health management of hatchery stocks Methods for evaluating stocking effectiveness Population management in stock enhancement and sea ranching Management of stocked populations Ecological interactions with wild stocks Genetic management of hatchery and wild stocks Socio-economics of stock enhancement Case studies Stock Enhancement and Sea Ranching has been written and edited by some of the world’s foremost authorities in fisheries science and related areas and is essential reading for all fisheries scientists throughout the World. Fish biologists, marine and aquatic scientists, environmental biologists, ecologists, conservationists, aquaculture personnel and oceanographers will all find much of use and interest within this book. All libraries within universities and research establishments where these subjects are studied and taught should have copies of this book on their shelves.
