Fraser River Salmon Run-size Estimation Workshop

April 22nd & 23rd, 2003 Pacific Palisades, Vancouver

On April 22-23, Fisheries and Oceans Canada sponsored a Run-size Estimation Workshop. The workshop was intended to review current run-size estimation methods used by the Pacific Salmon Commission, and to initiate planning with First Nations, stakeholders and Pacific Salmon Commission staff to collect additional information in order to develop improved in-season methods of estimating run size
and timing.

Pacific Salmon Commission staff provided conference attendees with an overview of the Pacific Salmon Commissions current assessment programs, and provided important criteria for planning future assessment fisheries which will generate useful data for run-size estimation models.

The following briefly describes a series of PowerPoint presentations that were delivered by Pacific Salmon Commission staff at the workshop:

Introduction to Fraser River Panel Management
- a review of the role of the Fraser River Panel and PSC staff in managing Fraser River sockeye and pink salmon, and an overview of pre-season and in-season management.

PSC Racial Analysis Program
- an overview of the methods employed by the PSC in assessing stock composition, including scale-based methods and new applications using DNA.

PSC Test Fishing Programs
- a review of current test fishing programs used by the PSC, and the increasing role of test fishing data in run-size estimation.

PSC Hydroacoustics Program
- an overview of the single-beam hydroacoustics program at Mission, and a review of the new split-beam program being developed to improve estimates of escapement past Mission.

Management Adjustments
- an explanation of why management adjustments are required, and a review of the methods used to calculate both pre-season and in-season management adjustments.

PSC Run-size Estimation Methodology
- a review of current methods used by PSC staff to estimate run size, and a summary of key limitations in existing models.

Potential Improvements to Run-size Estimates
- a review of issues relating to how best to improve run-size estimates, and to the costs and benefits of obtaining improved estimates.
