Résumé
Sebastes miniatus, the vermilion rockfish, vermilion seaperch, red snapper, red rock cod, and rasher, is a species of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. It is native to the waters of the Pacific Ocean off western North America from Baja California to Alaska. Sebastes miniatus was first formally described in 1880 by the American ichthyologists David Starr Jordan and Charles Henry Gilbert with the type locality given as Santa Barbara and Monterey, California. Some authorities place this species in the subgenus Rosicola. The specific name miniatus means "bright red" or "scarlet" a reference to the color of the vermilion fins and body. Sebastes miniatus has a rather stocky body shape with the depth of the body being equivalent to just under two fifths of its standard length. It has moderately robust to weak spines on its head, the nasal, preocular, supraocular, postocular, tympanic and parietal spines being always present, the nuchal spine usually being absent and the coronal spine never being present. The dorsal fin is continuous with a deep notch separating the spiny and soft rayed parts with the spiny part has a longer base than the soft rayed part with deep incisions on the membranes between the spines. There are 13 spines and 13 to 15 soft rays in the dorsal fin while the anal fin has 3 spines and 7 soft rays. The lower jaw is rough with large scales. It has deep caudal peduncle and the caudal fin has a slight fork. This species attains a maximum total length of and a maximum published weight of . The color of this species varies from dark red to vermilion with gray or black spotting on the back and flanks. Smaller fishes may have a more mottled pattern than larger fishes. The mouth is red mouth and the red fins are frequently have black margins, again more typical in smaller fishes. Larger individuals show indistinct dark markings on the head and back. There are three indistinct yellow or orange stripes radiating from the eyes.
