The International Game Fish Association announced yesterday that the 22 lb 4oz largemouth bass caught by Manabu Kurita in Japan last September has indeed tied the world largemouth bass record held by George Perry since 1932. The catch has been controversial as it was originally reported that the bass was caught in a no fishing zone in Lake Biwa. I am not sure if they found this to be true or not or whether it would effect the record if it was true.
In order for a fish to be declared the "world record" the IGFA must inspect the fish, usually cutting it open to make sure it's weight was not altered.
