opakapaka

Opakapaka, scientifically known as Pristipomoides filamentosus, is a species of deep-water snapper in the family Lutjanidae. It is commonly referred to as pink snapper or opakapaka and is highly valued in Pacific fisheries, especially in Hawaii, where it is a staple of commercial and recreational harvest.

Distribution and habitat: Opakapaka is native to the Indo-Pacific region, including the Hawaiian Islands, Johnston Atoll, and parts of the central Pacific. It occupies outer reef slopes and continental slope habitats, typically at depths from roughly 60 to 550 meters (200 to 1,800 feet). The species favors rocky and rubble bottoms and can be found both on seaward reef structures and in associated canyons and ledges.

Description: The fish has a moderately elongated, laterally compressed body. Color ranges from pink to reddish on the back and sides, with a lighter or pale underside. Fins are generally dusky to yellowish. Adults commonly reach lengths of around 40 to 60 centimeters, though individuals can vary by location and habitat.

Biology: Opakapaka feeds mainly on crustaceans, mollusks, and small fishes. Like many deep-water snappers, it tends to be slow-growing and late-maturing, factors that influence stock assessments and management. Reproductive biology varies by population, but lutjanids often exhibit complex sexual development patterns as they grow.

Fisheries and use: Opakapaka is a prized food fish and supports substantial commercial and recreational fisheries throughout its range, with Hawaii accounting for a large portion of its market. It is sold fresh or frozen and is valued for its firm, mild flesh. Management measures in various jurisdictions include size limits, catch quotas, seasonal closures, and gear restrictions to protect breeding stock and support sustainable harvest.
