Low tech fish tag

In this era when fish tags send instant messages to researchers and emit sound waves to communicate with receivers to track fish over long distances, it’s ironic that we rely on this old-school Floy tag as a backup to our expensive high-tech devices. This tag was recently inserted into the back of a striped bass to serve as a means of identifying this fish upon recapture, either upon the failure of the primary electronic tag, or after the tag’s battery life expires.
