Biologi     Ordlista (t.ex. epibenthic)

A generally active and free-swimming rockfish found in midwater above a rocky reef or steep shoreline; occasionally huddling motionless among caves and crevices (Ref. 27436). Young are found in shallow water (Ref. 2850). Form schools (Ref. 2850). Feed mostly on small pelagic crustaceans and fishes (Ref. 2850). Viviparous (Ref. 34817). Marketed fresh and frozen; eaten pan-fried, boiled, microwaved and baked (Ref. 9988).
