Wikipedia Abstract

The Quillback rockfish (Sebastes maliger) (also known as the Quillback seaperch) is one of 130 species of rockfish and primarily dwells in salt water reefs. The average adult weighs 2-7 pounds (0.9 – 3 kg) and may reach 1 m (3 feet) in length. Quillback rockfish are named for the sharp, venomous quills or spines on the dorsal fin. Their mottled orange-brown coloring allows them to blend in with rocky bottom reefs. Quillback rockfish eat mainly crustaceans, but they will also eat herring. They are solitary and minimally migratory, but not territorial, and give birth to live young (viviparous). They are a popular sport fish, generally caught in cold water 41–60 m deep, but also to subtidal depths of 275 m.
