Chilko River Chinook Salmon Mark-Recapture (Fraser River Summer-run Age 1.3 Stock Group)

The primary goals of the Chilko River Chinook Salmon Mark-Recapture Project are to develop and estimate the spawning abundance that meets or exceeds the Chinook Technical Committee data standard for escapement indicator stocks. Specifically to determine:

1) estimates of spawning escapement by age and sex that will, on average, attain a coefficient of variation (CV) of 15% or less on the spawner estimates; and

2) consistent estimates that are asymptotically unbiased.

Additional objectives include bias testing of application and recovery data, and improving the efficiency of the study in-season and annually.
