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.
