TBF Intern Integrates Angler Knowledge into Fisheries Management
For years, members of the sportfishing community have felt that scientists and fisheries managers should consult those on the water and in the industry when making decisions. Our community is able to “see” firsthand what is happening and can provide valuable input. Our latest Winthrop P. Rockefeller Student Ocean Program Intern, Briana Gibbs, performed an in-depth analysis of the value of this input and presented her findings to the International Commission for the Conservation of Atlantic Tunas (ICCAT). In her analysis, Briana identified key changes in fishing gear and technology that impacted the recreational catch of billfish between 1973
2019 Conservation Record
The Billfish Foundation’s Tag & Release Program. We received over 11,000 new tag, release, and recapture records for billfish and tunas.

TBF’s Juvenile Billfish Project
TBF’s newest project focuses on juvenile billfish for very little is known about them during their early life stages due to high mortality rates and a lack of reliable tracking methods for fish of their size. A lack of information on juvenile and newborn billfish whereabouts and habits leaves their management and advocacy for their survival in jeopardy. TBF with our research partner Dr. Freddy Arocha, TBF’s research partner and recipient of TBF’s Paxson Offield Lifetime Science Achievement Award 2019, shared that “known images from juvenile billfish are rare, and more difficult is to find an image with the
