Book Description
The augmented fish health monitoring project is funded by the Bonneville Power Administration with the mandate to collect fish health data on anadromous fish stocks of the Columbia River Basin in a standardized manner. The project began in 1986 and the data reported here was collected in the third year. This segment of the project was carried out by the Washington Department of Wildlife and summarizes fish health findings at anadromous game hatcheries in Washington State operated by the BPA. Information gathered to date has provided impetus to alter facility design and management practices for improved fish health through prevention. Treatment efficacy can be better assessed due to the monthly monitoring of fish stocks and insight is being gained into disease prevention and control. The ultimate goal, of course, is to improve fish health for better survival in the wild. Tagged returns at index hatcheries within this project area will indicate the impact of improving fish health on providing greater adult returns as well as an improved product for the fishery. 2 refs., 3 figs., 15 tabs.

Book Description
Since 1986 Washington department of Fisheries (WDF) has participated in the Columbia Basin Augmented Fish Health Monitoring Project. This project provides a standardized level of fish health information from all Agencies rearing fish in the Columbia Basin. WDF has actively participated in this project, and completed its second year of fish health monitoring, data collection and pathogen inspection during 1988. This report will present data collected from January 1, 1988 to December 31, 1988 and will compare sampling results from 1987 and 1988. The analysis will be divided in two sections: adult analysis and juvenile analysis. The adult analysis will include results from screening at spawning for viral pathogens and bacterial kidney disease (BKD), and evaluation of causes of pre-spawning loss. The juvenile analysis will include pre-release examination results, mid-term rearing exam results and evaluation of the Organosomatic Analysis completed on index stocks. Additionally, highlights from monthly monitoring exams will identify any significant and unusual findings from the routine exams completed in 1988. 6 refs., 8 figs., 14 tabs.

Book Description
This report documents the progress of various tasks during the second year of a five year augmented fish health monitoring project. Fish at Washington Department of Wildlife hatcheries rearing anadromous fish for the Columbia River drainage were intensively monitored either annually, semi-annually, or monthly for various pathogens of concern. We have developed a database for documentation of the presence and severity, or absence of these pathogens. In addition, we are progressing in the development of disease histories for these stations. The installations have been examined for impediments to good fish health both in terms of physical (structural and water supply) problems and loading problems. Recommendations have been made to correct these difficulties. 2 refs., 3 figs., 16 tabs.
