1992 Salmon and Steelhead Stock Inventory (SASSI) "Bluebook" INTRODUCTION This report documents the results of an initial stock status inventory that is the first step in a statewide effort to maintain and restore wild(1) salmon and steelhead stocks and fisheries. The inventory's intent is to help identify currently available information and to guide future restoration planning and implementation. While overall objectives and future steps of the restoration initiative are briefly described, the report primarily focuses on current condition of Washington's naturally reproducing anadromous salmonid populations and not on the adequacy of current resource management objectives. Assessment of management objectives and strategies will be one of many subsequent steps aimed at improving the status of wild salmon and steelhead resources in Washington. BACKGROUND A majority of salmon and nearly all wild steelhead runs in Washington are primarily managed to achieve natural spawning escapement goals. Numerically, many stocks are relatively healthy, and naturally reproducing populations still account for over half the total salmon and steelhead production originating from Washington's watersheds. However, many wild stocks are significantly depleted and most runs experience periodic problems. Annual and long-term resource management planning efforts are commonly undertaken to assess status of stocks and fisheries. Specific harvest, culture, and habitat measures have been recommended and/or implemented in many areas to maintain or improve the status of wild stocks (PFMC 1992). Despite the relatively healthy condition of many wild salmon and steelhead stocks, significant challenges face these resources in the Pacific Northwest. Factors such as habitat degradation, some poorly designed hatchery programs, and overfishing have contributed to the decline of many wild stocks to below historical levels (Nehlsen et al. 1991; PFMC 1992; WDF 1992). Recent petitions and/or listings have occurred under the Endangered Species Act (ESA) for anadromous salmonids in the Sacramento, Columbia, and Rogue River basins. Society's impacts have caused past and continuing loss of stocks, as well as diminished abundance, habitat, and genetic diversity. Major land use activities impacting wild salmonid habitat and survival (e.g. urban and industrial growth, forest practices, agricultural practices, municipal, industrial and agricultural diversions, and hydropower) have reduced Washington's salmon and steelhead production over the years and continue to do so at an escalating rate (WDF 1992). Resource management policies linked to production and harvest of hatchery fish also impact the status of many wild stocks. For example, of the 101 total salmon stocks or stock groupings in Washington that have defined and actively managed escapement goals (i.e. primary management units), about one-third are harvested at overall rates determined by hatchery escapement requirements, which may contribute to the depletion of commingled wild stocks. Hatchery programs have generated much public debate, ranging from views that fish culture represents the future of salmon and steelhead in the region, to beliefs that hatcheries are the primary reason that many wild stocks have become depleted. In at least some cases, the impacts of certain hatchery practices on wild stocks have been well-documented as related to factors such as straying, competition and predation. In the future, improved and better coordinated management of habitat protection, harvest management and hatchery production programs will be the key for designing comprehensive strategies to restore wild stocks and the region's fisheries. Evaluation and public support of these strategies will be essential to ensure success. WILD STOCK RESTORATION INITIATIVE Wild fish resources and their habitats must be protected and restored in order to maintain viable and healthy fisheries, and to provide for associated ecological, cultural, and aesthetic values. To accomplish this, state and tribal fishery managers have committed additional priority toward a Wild Stock Restoration Initiative (WSRI) that would complement and strengthen ongoing programs to protect healthy stocks and habitats. The managers' overall goal is to: Maintain and restore healthy wild salmon and steelhead stocks and their habitats in order to support the region's fisheries, economies, and other societal values. The WSRI has several objectives:
Productive aquatic ecosystems are essential for healthy salmon and steelhead populations that provide an important foundation for a strong Northwest economy as well as for a diverse cultural and natural heritage. Managing for stock health and related human benefits requires maintaining adequate resource abundance, productive habitat, and genetically diverse wild stocks. The Washington Departments of Fisheries and Wildlife (WDF and WDW) and Western Washington Treaty Indian tribes have jointly challenged themselves to create opportunities for a positive future that will feature productive aquatic habitats, healthy wild stocks, and adequate levels of fishing. Clearly, strong public support for solving complex problems will be necessary to realize this vision. The WSRI will provide additional focus and resources for the State's and tribes' current fishery resource management mandates. The initiative is intended to produce comprehensive management approaches to restore depleted salmon and steelhead stocks and avoid intensely disruptive and divisive reactions that can result from ESA petitions. RESOURCE STATUS INVENTORY This report is the first summary of a Salmon and Steelhead Stock Inventory (SASSI) of naturally reproducing fish in Washington State - the first step in the statewide Wild Stock Restoration Initiative. SASSI provides an approach for developing a list of salmon and steelhead stocks and a process for rating their current status. Stock lists, classifications and ratings will be updated as additional information becomes available. The concept of resource inventories is not new - fishery management agencies spend considerable staff time collecting and assessing resource status data, e.g. spawning escapements, harvests and biological parameters. This information is routinely used for decision-making but often is not well documented or visible outside the "management process." As a result, an objective of SASSI has been to develop a simple and consistent system of collating and reporting statewide salmon and steelhead resource assessment information, recognizing the inventory will change over time. For the Columbia basin, this initial inventory incorporated information already available from the subbasin plans and recently summarized as part of the Coordinated Information System project. In the Coastal and Puget Sound regions, state and tribal biologists collated data from a number of sources within the management entities. Future updates of SASSI and associated reports will evolve as necessary to accommodate new information and be integrated with developing regional resource information systems. The planned growth and refinement for SASSI is an important point. This initial report, and related data collation, was developed in a short time period - about nine months. Given the large number of stocks in the inventory, the amount of detailed data and depth of analysis has been strictly limited by the schedule. This report is meant to provide a first glimpse of current stock status and build a foundation for future restoration and inventory efforts. In addition to highlighting the inventory's intent, it is important to note that SASSI is not:
Clearly these and other steps will be necessary and are anticipated to follow the inventory, but this first SASSI report simply is intended to build a foundation for the WSRI. The subsequent steps and the process envisioned for the overall initiative are presented in Part 3 -- Current and Future Actions. It should be noted that the status information in this first report largely relates to numerical abundance rather than interpretation of genetic fitness. This initial orientation is not intended to discount the importance of any stock's genetic status but reflects a subsequent need to perform genetic risk assessments throughout the state in a systematic manner. Many genetic impacts to the region's wild stocks have occurred over time from cumulative impacts of habitat degradation, harvest policies and hatchery practices. Most stock abundance problems identified in the 1992 inventory have related genetic concerns that will be carefully evaluated during the restoration development phase. State and tribal biologists involved in the inventory also have been alert to identify current or new genetic impact issues that may require priority attention. Stock origin (native, non-native and mixed) has been presented for each stock and discussions about potential genetic influences have been included in the regional appendices. Report Content and Organization The 1992 SASSI report is organized so that the reader proceeds from general discussions to more detailed information used in the process of identifying individual stocks and determining their status. This report highlights the general background of the inventory effort and provides a summary of stock status for the reader who may not desire to review the stock status detail found in three regional appendices. The report is comprised of the following sections:
Regional Appendices Three supplemental appendix volumes provide specific information on each stock currently listed in SASSI for the Columbia River, Coastal, and Puget Sound regions. These appendices are organized by basins with an overview description for each species, followed by individual Stock Reports. Each Stock Report includes a:
