The International Angling Rules have been formulated by the International Game Fish Association to promote ethical and sporting angling practices, to establish uniform regulations for the compilation of world game fish records, and to provide basic angling guidelines for use in fishing tournaments and any other group angling activities.

The word "angling" is defined as catching or attempting to catch fish with a rod, reel, line, and hooks outlined in the international angling rules. There are some aspects of angling that cannot be controlled through rule making, however. Angling regulations cannot insure an outstanding performance from each fish, and world records cannot indicate the amount of difficulty in catching the fish. Captures in which the fish has not fought or has not had a chance to fight do not reflect credit on the fisherman, and only the angler can property evaluate the degree of achievement in establishing the record.

Only fish caught in accordance with IGFA international angling rules, and within the intent of these rules, will be considered for world records.
