aku

The word "aku" is universally used across Hawaii by fishermen, chefs, and everyday locals to refer to skipjack tuna. It is a fundamental part of the island diet and vocabulary, deeply rooted in Native Hawaiian fishing traditions where aku was caught using pearl-shell lures. Today, you will hear the term at fish markets, grocery store seafood counters, and family gatherings, especially when discussing poke, sashimi, or dried fish.

Culturally, aku holds a nostalgic place in Hawaii's plantation and maritime history. The Japanese immigrant community heavily influenced how it is prepared, often referring to it as "katsuo" and using it for katsuobushi (bonito flakes) or serving it raw with soy sauce and ginger. Unlike the larger and more expensive 'ahi (yellowfin tuna), aku has a richer, bloodier flavor and softer texture, making it a prized catch for those who appreciate old-school, traditional local food. It is always appropriate to use "aku" instead of "skipjack" in Hawaii; in fact, using the English name will immediately mark you as a visitor.

The sky over Ma'alaea small boat harbor was still a bruised purple when Frank backed his rusted Toyota Tacoma up to the slip. The salt air smelled exactly like it did forty years ago, thick with diesel and damp nylon nets. He killed the engine and watched Kawika tying off the stern line of the boat, the deck lights casting long shadows across the wet fiberglass. They had been out past the buoys since two in the morning, chasing the birds.

"How we looking?" Frank called out, his voice raspy from the unfiltered cigarettes he swore he quit. Kawika just grinned, hauling a heavy, silver-blue torpedo over the gunwale. The aku was thick, its dark stripes gleaming under the halogen bulbs. It was the kind of catch that brought back memories of the old sampan fleet, back when the harbor was packed shoulder-to-shoulder with wooden boats and old Japanese men yelling over the roar of the engines.

Kelsey pulled up a few minutes later in her beat-up Honda Civic, clutching a thermos of black coffee. She took one look at the insulated fish bag Kawika was filling with ice and nodded. "Bachan going be happy," she said, handing Frank the steaming cup. "Nothing beats fresh aku for the sashimi platter tonight. You guys actually did good for once." Frank just chuckled, taking a sip of the scalding coffee as the sun finally broke over Haleakala.
