The International Game Fish Association is a not-for-profit organization dedicated to game fish conservation and research. Created in 1939, the IGFA maintains world records for both freshwater and saltwater game fishes. Records are divided by line class, tippet class and all-tackle categories. The IGFA introduced a new all-tackle length category in 2011, keeping separate records for length. Entries in this category must be measured on an official IGFA Measuring device — all fish must also be released alive and unharmed.

To qualify for weight records, a fish must weigh a minimum of one pound. With the exception of all-tackle records, anglers must submit their claim to the IGFA within 60 days of the date of catch for fish caught in U.S. continental waters. Applications for fish caught in other bodies of water must be received within three months of the date of catch.

In order for a fish to qualify for an IGFA record, it must be weighed on a certified scale. Anglers must also submit a completed IGFA form, mandatory length of line and terminal tackle used to catch the fish, plus photographs. For more information, visit the IGFA website.
