Support Billfish Research

Donate to the IGMR


The IGMR is presented by Costa® Sunglasses and is a partnership between the IGFA and Stanford University that pairs recreational anglers with cutting-edge satellite tag technology to learn more about the basic biology of billfish and how they utilize their open ocean habitat. The program was launched in 2011 and, since that time, we have tagged 439 billfish in 21 countries.



* The CARES Act includes several provisions to encourage charitable giving for United States tax payers. For individuals that are itemizing, the adjusted gross income (AGI) for cash contributions was increased. You can now elect to deduct up to 100% of your AGI (increased from 60%). Not itemizing? The CARES Act allows for an additional “above-the-line” deduction for charitable gifts made in cash of up to $300. Tax laws vary from state-to-state and person-to-person. Please consult your tax advisor for your particular situation.
