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
Tropical Tuna Tagging Program Extended
The Billfish Foundation (TBF) is looking for anglers and crews interested in tagging tuna in the Northern Atlantic. TBF is working with scientists from the Atlantic Ocean Tropical Tuna Tagging Program (AOTTP) to learn more about certain tuna species. This program, which is part of the International Commission for the Conservation of Atlantic Tunas (ICCAT), looks to study key aspects of bigeye, skipjack, and yellowfin tuna life history and movements in the Atlantic Ocean. The AOTTP partners with scientists and commercial and recreational tuna fishermen to tag tropical tuna with AOTTP-specific conventional and/or electronic tags throughout the Atlantic
Blue Marlin Satellite Tagging in the Gulf of Mexico
Because overfished Atlantic marlin receive no government research funding priority, large data gaps relating to their life history characteristics remain. Satellite tagging provides a means to fill some of the data gaps by recording a marlin’s location and movement in the water column, both horizontal and vertical. Each tag records variables in sunlight levels, water temperature and pressure that is converted to location and movement. Movement data then provides insight to such elements as whether oil rigs, which serve as large Fish Aggregation Devices (FADs), modify marlin movements and whether marlin remain in the region all year because
New Blue Marlin Study Illuminates Age-Length Relationship
A new TBF-supported study out of the University of Miami made great strides in understanding the relationship between age and growth of Atlantic blue marlin. The study examined growth annuli in anal fin spines of 1,638 blue marlin caught as bycatch in Venezuela to determine the age of each fish. Growth annuli are small rings inside of the fin spine that increase in number as the fish ages, much like the rings in a tree trunk. They then correlated this age information to the lower jaw fork length (LJFL) to determine how well LJFL predicts fish age. The study found
Satellite Tagging Expedition – Gulf of Mexico Blue Marlin
TBF’s most recent satellite tagging expedition kicked off with a fantastic crowd all interested in learning more about blue marlin in the Gulf of Mexico and how to help with tag deployment. Tag program sponsors Costa and Yeti actively participated and had a videographer capture all the action. The New Orleans Big Game Fishing Club provided the perfect location and libations at its new Club House within the confines of the Cypress Cove Marina and Lodge’s property. An over-the-top seafood extravaganza was sponsored by the Louisiana Seafood Board, thanks to Lt. Governor Billy Nungesser and the Cypress
Tagging Tuna with ICCAT and AOTTP
The Billfish Foundation is currently engaging in a research project with Atlantic Ocean Tropical Tuna Tagging Program (AOTTP) in order to further the knowledge around lifecycles of yellowfin, bigeye, and skipjack tuna. This will be accomplished by working with recreational and commercial anglers to implement traditional ‘spaghetti’ tags into these different species of tuna. This research is very valuable and important to the multiple regional and national fisheries associated with these different species. For example, this work will be very important with the yellowfin tuna fishery in the northern Gulf of Mexico. On a base level, this research will

Atlantic Blue Marlin Research
Atlantic blue marlin are considered by many in the sportfishing world to be THE pinnacle gamefish. A species targeted by tens of thousands anglers each year. But what do we know about these magnificent and awe-worthy fish? To be honest, not enough. We are still scratching the surface of what we know about them compared to other marine species. For example, age and growth research is basic and well documented for most species caught in commercial fisheries where data collection is readily available, but not so for billfish. TBF spearheaded research on this very topic on Atlantic blue
Learning to Fish Via Youtube?
Sportfishing is an art/skill that cannot be mastered quickly. It takes time, energy, failure, and money to become an accomplished angler. The interesting aspect of fishing is the pressure that goes along with it. Many fishermen are not “professional” and have regular day jobs. Thus, they may only fish a couple times a month or a few times a year to hone their skill. Due to this, there is stress to try to make every trip a fantastic event because of the irregularity of trips. Plus, fishing is a hands-on sport. For example, pitch baiting marlin is not
Florida East Coast Closed Zone Will Remain Closed!
The National Marine Fisheries Service (NMFS) is not issuing an Exempted Fishing Permit (EFP) that would open the east coast Florida closed zone to pelagic longline vessels for the stated purpose of conducting “research.” Thanks in large part to TBF’s efforts and to our constituency submitting comments to NOAA, this victory was achieved. This is a major accomplishment that will continue yielding conservation benefits to the fish and other marine resources, which will further support recreational fishing and boating opportunities that support a wide array of associated jobs. The decision comes after almost two years of effort
