Objectives for 2009

Estimate in-river survival rates, migration rates and impact of fisheries on in-river survival for sockeye and chinook.Test new approach for estimating species composition at Mission using Whonnock, fishwheel and Qualark dataWork with PSC to derive reliable in-season estimates of abundance at Mission for sockeye, chinook and pink salmon.

Conclusions from 2009Fishwheels at the Crescent site

caught more fish of all species than previous years at Crescent and Missionhigh catch rates during the pink migration limited fishwheel operations to daylight hours

Combination of Whonnock and fishwheel data and spatially stratified hydroacoustic counts appears to be a viable solution to the Mission species composition problem. Radio-telemetry and Qualark hydroacoustic data were used in-season to estimate sockeye passage at Mission.

3/8/2010 47

Conclusions from 2009 (continued)

En-route losses appear to be related to higher water temperatures during migration

highest en-route losses during late July when water temperatures were highlowest en-route losses for sockeye migrating in early July and Septemberen-route losses experienced significantly higher temperatures than fish tracked to spawning areassimilar results were derived from analyses of 2005-07data for summer-run sockeye.

All available data for Fraser sockeye CUs and stocks has been integrated into the run reconstruction analyses for 2002-07.

3/8/2010 48

Objectives/Proposal for 2010obtain daily estimates of the near-shore species composition using the Crescent Island fishwheelsobtain weekly DNA and biological samples from fishwheel caught sockeye and chinook to augment the Whonnock test fishery samples; assess in-river survival rates for Early Stuart sockeye using fish capture by fishwheels when water temperatures are low; assess river entry timing and survival rates for other sockeye run-timing groups using fish captured using marine purse seines;

3/8/2010 49

Objectives/Proposal for 2010 (continued)

identify the times and locations where any en-route losses of radio-tagged sockeye occur in 2010; more detail assessment of major en-route loss locations using additional fixed-station receivers, mobile tracking, and catch sampling data; continue work with First Nations, DFO, PSC and universities on analyses that integrate all available data into pre-season planning, in-season management and post-season assessment tools for Fraser sockeye.
