About Chad

The Story Behind the Name: Chad is named after a fisherman in the Florida Keys who helps with shark tagging trips, often obtaining the snapper or barracuda with which we bait the shark hooks. He may give off that salt-encrusted, rough seaman vibe, but in truth, he’s a softie when it comes to helping out the creatures of our oceans. We are greatly appreciative of all the time and effort he contributes to SRC.

Satellite Tagging: Chad was carefully tagged with the latest in satellite tag technology providing us with the first opportunity to follow the long term movements of these threatened species. Please keep checking back frequently to follow Chad’s movements, which will be updated every few days as his satellite tag continues to send us real-time tracking data.
