New Striped Marlin Study
Scientists have recently discovered that predatory fish, such as the striped marlin, use rapid color changes to coordinate their attacks on prey. The study found that the marlins use these color changes to communicate with each other during hunting, allowing them to work together more effectively. By adjusting their color patterns, the fish are able […]
Costa’s Marlin-Fly Project
For years, we have all heard about the amazing fishery and waters in Magdalena Bay, Mexico. From the hookups of doubles, triples, and quads of striped marlin with daily releases in the triple digits, it is not surprising that a number of our tag and release winners utilize this incredible location to secure some of our top annual awards. While the fishery as a whole may be renowned by offshore anglers, our current knowledge about the striped marlin fishery in particular is merely surface level. As always, our goal is to conserve, educate, and promote sustainable fishing in locations
Pacific Striped Marlin Rebuilding Plan
Western & Central Northern Pacific striped marlin, whose abundance, especially spawning-stock biomass, and size are greatly diminished and retain low priority within the Western & Central Pacific Fisheries Commission (WCPFC). This regional fisheries management organization (RFMO) is tasked with the management of this and other highly migratory species. Unfortunately, its interim rebuilding plan for the species which includes goals to be achieved by 2034 has no chance of success. More aggressive conservation and management measures by WCPFC to reduce post-release mortality need to be considered, which can be done with little impact on longlines catching its targeted species
2020 Conservation Record: Striped Marlin
The Billfish Foundation maintains the largest private tag and release database in the world, with 260,000 records by 150,000 anglers. In 2020 alone, TBF anglers and captains tagged, released, or recaptured 7,000 billfish and tuna across the world. Of these 7,000 new records, 1,963 were of striped marlin. Striped marlin (Kajikia audax) are native only to the Pacific and Indian Oceans. They can grow up to 12ft long and over 450lbs. Information on how to identify a striped marlin can be found on our youtube channel. Thank you to everyone that tagged and released striped marlin last year
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. These data are used by researchers and management organizations across the globe, helping us learn more about these great fish and how best to conserve them. Below is a link to a PDF of the final 2019 Conservation Record, including black marlin, blue marlin, sailfish, spearfish, striped marlin, swordfish, white marlin, bluefin tuna, and yellowfin tuna. 2019 Conservation Record Final This feat of citizen science would not be possible without the generous support of our Tag &
2019 Conservation Record: Striped Marlin
The Billfish Foundation maintains the largest private tag and release database in the world, with over 260,000 records. In 2019 alone, over 11,000 new tag, release, and recapture records were added to this database, representing an enormous amount of data to help us learn more about billfish life history. Of these over 11,000 new records in 2019, 2,536 were of striped marlin, including 6 striped marlin recaptures. 84% of striped marlin were released without tags, while 16% were tagged. To learn more about how to identify a striped marlin, check out our youtube channel! 413 striped marlin were tagged
2019 Tag & Release Competition Winners
Each year The Billfish Foundation recognizes the best of the best in the billfishing community to acknowledge the significant effort they contribute to our Tag & Release Program and billfish conservation. Since its inception in 1990, the program has grown to accrue over 260,000 tag and release records to become the largest private billfish tagging database in the world. In the last year alone, TBF has collected over 11,000 records! The information gathered through tag and release efforts is invaluable to increase our understanding and better our management of billfish and preserve the sport we love. This is only possible
What are billfish?
In General TermsÂ- The term “Billfish” refers to various predatory fish species typically belonging to the taxonomical family Istiophoridae. Their biological characteristics include a spear-like rostrum or “bill,” which is used for slashing at and stunning prey. The dorsal fin of these species runs along a large part of their body and narrow pelvic fins. Billfish can be found spread throughout the worlds oceans and are defined as highly migratory species but typically reside in tropical or sub-tropical waters. The prey of these apex predators differs from a variety of small fishes to crustaceans and cephalopods (i.e. squid)
