Striped Bass with Satellite Tag


Gray FishTag Research
is an international and fully interactive fish tagging program powered by the world’s largest network of fishing professionals consisting of approximately 10,000 charter boat captains and mates.

Our fish tagging program is an essential tool for promoting the sustainability of marine game fish and increasing public resource awareness. We are collecting information in real-time, producing valuable scientific data, directly from fishermen in waters world-wide. We are connecting professional fishermen and angling enthusiasts with the scientific community who are all desperate for relevant data.

All data collected is being analyzed and used for scientific purposes and shared with any and all interested parties at NO COST.

All fish species in every ocean are being monitored. Billfish, sharks, general offshore and inshore fish species are being tracked and recorded. Results provide valuable information on migration patterns, fish stocks, growth rates, habitat depths and much more.

Gray FishTag Research Tagging Expeditions

We have successfully carried out several research and tagging expeditions where teams combined of local captains, mates, event sponsors, research center personnel and scientists, set out with the goal of deploying Satellite Tags (PSAT’s) and conventional “spaghetti” tags on various fish species. Roosterfish, Blue Marlin, Striped Marlin, Swordfish and Striped Bass! have already been tagged and some very interesting data has already started to come in.

We are always exploring new initiatives and opportunities and we welcome anyone interested to support and participate in any future Research Expedition. So if you looking for a fishing experience of a life-time, do not hesitate to let us know.

Through generous support we continue to expand our program to new territories. This is allowing us to learn more about our amazing fisheries while sharing the information to the public at no cost.


Gray FishTag Research (GFR) is a 501(c)(3) Non-profit organization. The success of the program is made possible by the generous commitment and participation of the hard working charter fishing captains and mates, fishing professionals and staff members at our Research Centers. These partners are actively advocating and introducing the Gray FishTag Research program to their visitors and customer base.
