Tiger Rockfish by Adam Harding, summer, 2010

Sebastes nigrocinctus, the tiger rockfish is striped like a tiger, feature shades of pink, grey or rose, with five black or red bars radiating backwards from the eyes. Bony ridges on the head may also distinguish them from other species. In younger individuals, tips of the ventral and anal fins are darkened. Tiger rockfish reach lengths of 35 cm by 17 years of age; their maximum size is reportedly 61 cm.

Distribution and Habitat:
Since the establishment of the Rock Fish Protection area around Race Rcoks after 2002, these fish are now protected.

They occur from shallow water to 305 m. They are generally found in waters less than 30 m in Puget Sound. Off Oregon, the species is usually found at depths of 64-305 m. In the northeastern Strait of Georgia, tiger rockfish are generally captured in 21-140 m of water.
Juveniles of the species are pelagic, while adults are semi-demersal to demersal. Tiger rockfish are commonly found in caves along undersea cliffs or on the sea floor, generally in high relief areas with strong currents. It was noted that tiger rockfish are often associated with "wall" habitat. Young have been noted resting among gooseneck barnacles near Triangle Island, British Columbia. Off southeast Alaska, habitat requirements for tiger rockfish are similar to those of Yellow Eye and China rockfishes. Juvenile tiger rockfish were observed around rocky reefs, as shallow as 9 m.

Trophic interactions:

Tiger rockfish are solitary, sometimes territorial, and are known to prey upon caridean shrimp, crabs (particularly rock crabs), amphipods and small fishes like herring and juvenile rockfish in the Gulf of Alaska . This species is a generalized feeder that depends on currents bringing food items near its home territory.
