8mm x 1.4mm "skinny" tag. We hope to tag juvenile fall Chinook in the Hells Canyon Reach of the Snake River. This is for Dr. Billy Connors ongoing beach seining surveys.
I haven't been able to find any product testing. I contacted Alan Brower and he confirmed that they had not tested these tags. Also, their testing schedule is full and they would not be able to do any testing until fall.
We used these tags in a small lab study (Rabe et al. Survival, Growth, and Tag Retention of Age-0 Chinook) and they performed well for us there. The number of these tags we are hoping to put in the system is relatively small (2,000-4,000).
