After World War II and up to the early 1980s, the pole & line fishery for aku (skipjack tuna) was the main supply of fresh tuna for sashimi and canning raw material in Hawaii.
This fishery involves two different types of fishing: the first to capture live bait and the second to catch skipjack tuna. Chumming aku schools with live bait keeps them near the boat. Fishermen then use feathered lures with barbless hooks attached to bamboo poles to catch the fish.
