Hi All,
As some of you know I work with PSF on a couple of research projects. One of these is the Bottlenecks to Survival study. Funded by BCSRIF and led by PSF and the BCCF Aquatic Research and Restoration Center, this study is using PIT tags to try to understand key mortality periods (bottlenecks) for Chinook, Coho and Steelhead, and conducting focused studies to identify mechanisms of mortality at those potential bottlenecks.
Recently I was contacted on here about a PIT tag recovered by a forum member from the body cavity of a fish off Nanaimo. These tags are glass capsules about the size of a grain of rice (right hand tag in photo below with a 16.5 cm / 6 inch Chinook) and contain a visible copper coil.
Tags will be loose in the body cavity of the fish or adhering to internal organs... they are inserted just in front of the pelvic fins, but could be elsewhere in the body cavity. If you find one we would love to scan it, document the fate of that fish (survived to adulthood and harvested) and provide you with information on its history. You can mail tags to the BCCF ARRC at:
Aquatic Research and Restoration Centre
105 – 1885 Boxwood Road
Nanaimo, BC V9S 5X9
or email bottlenecksvolunteerdata@gmail.com and/or send me a DM to discuss meeting up to scan the tag. Also keep an eye out for acoustic tags (the top left picture above). We are also applying some of these which are easier to see and are also in the body cavity of the fish.
