Onaga, known as Hawaiian Long-tailed Red Snapper (Etelis coruscans), is a prized deep-water fish native to Hawaiian and Pacific Island waters. Sold whole and wild-caught, this fish is celebrated for its delicate, moist, and mildly sweet white flesh with a fine, tender texture.

Onaga is considered one of Hawaii's most esteemed fish and is a centerpiece of Hawaiian culinary tradition. The whole fish is ideal for steaming, baking, or grilling, and pairs beautifully with ginger, scallions, soy, and sesame preparations. Its skin crisps well under high heat, while the flesh stays juicy and flavorful. Whole fish retains moisture and flavor better than fillets and is well-suited for presentation-style cooking.
