Redstripe rockfish are inshore rockfish found in the North Pacific Ocean. Like many other members of the rockfish family, they have a range that extends from Alaska in the north to California in the south. They live at depths ranging from about 10-400 metres, usually congregating in schools, but occasionally alone.

Redstripe rockfish have a short, deep body with a large head. Along their back is a row of pointy dorsal spines followed by flatter, softer dorsal rays, which together cover most of their length. Redstripe rockfish grow to a length of about 60 centimetres, though in Canadian waters they rarely reach more than 50 centimetres. They can live for about 50 years.
