Nass Sockeye Mark-Recapture Assessment Project

We propose to assess mark-rates of Sockeye (and tag loss) at the Kwinageese weir and include these data in the mark-recapture while simultaneously assessing spaghetti tag loss, observer efficiency, and potential selective removal of spaghetti tagged fish. This will be achieved through implementing Passive Integrated Transponder (PIT) technology alongside our traditional spaghetti tagging program.
