Uku is commonly known as the Hawaiʻi blue-green snapper. This fish shares many of the same qualities that have given opakapaka and onaga their reputations as outstanding table fish. Like other Hawaii snappers, uku has clear, translucent pink flesh that is delicately flavored, moist, and firm. Uku caught in the summer season is often rich in healthy fish oils and excellent as sashimi. Line-caught, mostly with vertical hook-and-line gear, this bottomfish is caught in shallower waters no deeper than 360 feet. Uku is caught year round in Hawaiʻi, with the greatest availability between May and July. Learn More.
