Yellowfin tuna were subsequently discovered by sport fishermen in Bermuda, the Bahamas, Hawai'i, and many other parts of their range. Larger adult fish which had developed distinctively long sickle fins were initially thought to be a different species and were known as Allison tuna (a name first given by the then curator of the Bermuda Aquarium, Louis Mowbray, in 1920). Such destinations as Hawai'i and Bermuda became famed for their catches of these beautiful fish. In Hawai'i, various styles of feather lures served as bait, but in Bermuda, chumming techniques from boats anchored on productive banks were evolved to target not only Allison tuna, but also wahoo and the smaller blackfin tuna. Bermudian experts developed techniques to take all these fish on light tackle, and for many years the International Game Fish Association records for yellowfin tuna were dominated by entries from Bermuda in the lighter line classes, with fish in the and larger class from Hawai'i taking most of the heavier line-class records.
