Our New Conservation Record is out!

  TBF’s 2021 Conservation Record has officially been completed and the results are in! Sometimes it can be hard to summarize all the hard work done in a year’s time, but this report acts as a really good start. In total, there were 11,822 new data entries added to The Billfish Foundation’s database in 2021, […]

2020 Conservation Record: Blue 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, 1,263 were of blue marlin. Like with sailfish, there is some debate on the difference between Atlantic and Indo-Pacific blue marlin. Makaira nigricans refers to Atlantic blue marlin, while Makaira mazara are Indo-Pacific. Blue marlin can measure up to 2,000lbs and 12ft long. Like other species of billfish, the Indo-Pacific blue marlin tend to be larger

2020 Conservation Record: Sailfish

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, 2,908 were of sailfish. Sailfish (Istiophorus platypterus/albicans) are native to the Atlantic, Pacific, and Indian Oceans. Istiophorus albicans refers to the Atlantic sailfish, while Istiophorus platypterus refers to the Indo-Pacific sailfish. However, many use Istiophorus platypterus for both, as there is little difference between the two aside from size and location. Here, The Billfish Foundation also

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

2020 Conservation Record: White 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, 270 were of white marlin. White marlin (Kajikia albida) are native only to the Atlantic Ocean. They are often confused with roundscale spearfish (Tetrapturus georgii) as the two species appear nearly identical. For that reason, most regulatory agencies combine their management. Because of this, and because identification between the two is unreliable, TBF also combines the

2020 Conservation Record: Swordfish

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, 169 were of swordfish. Swordfish (Xiphias gladius) are the only billfish species of the family Xiphiidae (as opposed to Istiophoridae). They are native to all oceans, but the vast majority of our records originate in the Atlantic. Information on how to identify a swordfish can be found on our youtube channel. Thank you to everyone that tagged

2020 Conservation Record: Black 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, 74 were of black marlin. Black marlin (Istiompax indica) are one of our lesser reported species and are native only to the Pacific and Indian Oceans. They are one of the largest species of billfish, with records up to 15ft long and 1,600lbs. Information on how to identify a black marlin can be found on our

2020 Conservation Record: Spearfish

The Billfish Foundation maintains the largest private tag and release database in the world, with over 260,000 records by over 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, 44 were of spearfish. Spearfish are the least represented billfish in the TBF dataset, making every new report that much more important. Thank you to everyone that tagged and released spearfish last year.
