The Billfish Foundation's Tag & Release Program has the largest private billfish tagging database in the world and remains a cornerstone of TBF's work, providing scientists with vital information gathered by thousands of volunteer fishing teams. The traditional tagging data reveals details such as migration patterns, age and growth rates, diving depths and sex ratios, all adding to a knowledge base that advances billfish science and, in turn, billfish management policies.
It is only through the participation of anglers, captains and mates that TBF is able to gather this vital tag and release data. Every fish that is tagged, released and recaptured provides us with one more piece in the puzzle of the mysterious lives of billfish. Additionally, documenting tagged and/or released billfish also illustrates the socio-economic importance of recreational fishing to our policy makers. Your participation makes a valuable contribution towards realizing a brighter future for billfish, our oceans, and related economies!
