Working worldwide to advance the conservation of Billfish & associated species to improve the health of oceans & economies.


The Billfish Foundation (TBF) was established in 1986 by scientists and concerned anglers who were worried about dwindling billfish stocks and the future of sportfishing. Working worldwide, TBF’s research programs are the backbone of our advocacy and education efforts to ensure that fish stocks are protected and ample sportfishing opportunities are available for future generations. Utilizing both scientific and socio-economic research to show the importance of healthy billfish stocks and impacts on recreational fishing, TBF works with international fisheries management organizations and governments to increase conservation measures that benefit both fish and local communities dependent upon sportfishing.
