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

Kicking Plastic with Costa Sunglasses at the Miami Boat Show

The Billfish Foundation was honored to be a part of Costa Sunglasses’ Conservation Village, within the Miami Boat Show this year. The venue provided the platform for many conservation organizations, including The Billfish Foundation (TBF) and marine regulatory agencies, to exhibit and share their conservation message with show visitors. TBF was able to talk about the various work we have been working on like tagging program and our recent age and growth work on Atlantic blue marlin. The Village, popular with students of all ages, who seemed aware of the need for ocean conservation yet were unaware of the

Recreational Billfish Landings Update

The table below provides preliminary 2018 (January 1, 2018 through September 30, 2018) landings in numbers of fish for Atlantic blue and white marlin, roundscale spearfish, and western Atlantic sailfish.  With most of the billfish tournaments are complete now, we can see as stated in a previous post, that the recreational community will be well below not only the 250 quota but should be below the 2017 numbers. Landings are compiled using self-reported angler reports from the Atlantic Highly Migratory Species (HMS) Non-Tournament Recreational Swordfish and Billfish Landings Database; tournament landings from the Atlantic Tournament Registration & Reporting (ATR)

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

Analysis of Minimum Length for Blue Marlin Tournaments

The Billfish Foundation’s newest Winthrop P. Rockefeller Ocean Program intern, Nick Becker, a recent graduate from Duke University’s Nicholas School of the Environment, worked with blue marlin tournaments out of the Gulf of Mexico for his thesis. His project was to evaluate the size minimums on harvested blue marlin. In order to be harvested, blue marlin must meet the federal size minimum of 99 inches in length. While most blue marlin tournaments have larger size minimums than the federal minimum; however, in some cases, there is room for improvement. Specifically, Nick’s master’s thesis, in conjunction with Dr. Grant

Sargassum Invasion

Weed, Weed – too much of a good thing? Offshore anglers know seeing and fishing a floating Sargassum weed line is a good thing for it they usually are very productive for catching dolphin fish and, if lucky, possibly a marlin. Sargassum is a brown-green microalga, or seaweed, which provides habitat for a significant variety of marine species, particularly juveniles seeking shelter from larger prey species. The structure of the Sargassum plant, includes a stem or stipe attached lateral branches with slender leaves and some have berry-like bladders that fill with air and provide buoyance. The weed plants often

Bill introduced to phase out large-mesh drift gillnets off California

The practice of allowing the U.S. west coast fishery to still use large mesh drift gillnets is insane. The fact that this method of fishing is still allowed shows how much influence the commercial fishing industry has with the federal fishery management council. Large mesh drift gillnets have been recognized as destructive for decades. The gear is not compatible with conservation, responsible fishery management or responsible use of public marine resources. This gear is already banned in the Atlantic Ocean and Gulf of Mexico, as well as off many parts of the west coast. Additionally, the United States is a signatory to international agreements that ban large drift nets in international waters. So why are they still

Why Are Billfish Threatened?

The Billfish Foundation was the result of a movement led by anglers who began noticing there were fewer big fish to catch. At the time, billfish tournaments featured piles of dead fish and commercial vessels sold billfish on the docks. Win Rockefeller, Dr. Eric Prince, and a group of 50 founding members recognized the unsustainable way billfish were being managed, in addition to the low priority they had with the government, and sought to protect these species through research, advocacy, and education. Today’s billfish tournaments look a lot different. Many release the fish that are caught, abiding to the

Assessing Florida’s Sailfish Population

Management of sailfish in the Atlantic Ocean falls under the International Commission for the Conservation of Atlantic Tuna (ICCAT), which is responsible for tuna and associated species like billfish. The first official stock assessment for Atlantic sailfish was completed by this management body in 2009, and identified two separate stocks: the eastern and western. In Florida, anglers interact with the western Atlantic sailfish stock, which was found to be overfished and likely undergoing overfishing. The most recent assessment, done in 2016, states that both sailfish stocks of the Atlantic Ocean suffered the greatest declines in abundance prior
