IGFA is an acronym for: International Game Fish Association. They are a not-for-profit organization committed to the conservation of Game Fish and the promotion of responsible, ethical angling practices through science, education, rule making and record keeping.
"IGFA's objectives are founded on the beliefs that game fish species, related food fish, and their habitats are economic, social, recreational, and aesthetic assets which must be maintained, wisely used and perpetuated; and that the sport of angling is an important recreational, economic, and social activity which the public must be educated to pursue in a manner consistent with sound sporting and conservation practices."
