California Coastal Chinook Salmon Fishery Management: Future Prospects.

摘要

A joint National Marine Fisheries Service and California Department of Fish and Wildlife workshop with the title “California coastal Chinook salmon (CC-Chinook) fishery management: future prospects” convened in Santa Rosa, California, September 3-4, 2014. The goals of the workshop were to identify the level of information necessary to allow for development of an abundance-based fishery management (ABM) approach and evaluate the feasibility of collecting that level of information for the CC-Chinook salmon Evolutionarily Significant Unit (ESU). Workshop participants noted that the collection of sufficient data to enable ABM will be difficult to achieve in the CC-Chinook salmon ESU. The level of data needed for ABM is greater than the level of data currently collected, and is greater than the level of data that would be generated with full implementation of the California Coastal Monitoring Plan (CMP). There are substantial technical difficulties associated with spawner surveys in the ESU and new programs would need to be developed to obtain ocean harvest data. Looking toward the future, important steps include (1) addressing the technical challenges associated with implementation of the CMP and moving toward full implementation, (2) giving consideration to a pilot study aimed at assessing the feasibility of marking and tagging programs that would provide sufficient information for estimation of ocean harvest and enable cohort reconstruction assessments, and (3) identification of stable funding for this monitoring work.?
