Tiger rockfish can grow up to 24 inches in length and weigh 7.5 pounds.
Habitat
Rocky reefs of the shelf and continental slope/basin and within crevices. Found at depths from 30 to over 900 feet.
Diet
Fish and crustaceans including shrimp, crabs and amphipods.
Life History
Tiger rockfish are territorial and live in solitary.
Fertilization of eggs and embryo development occur internally. A female tiger rockfish gives birth to live larval fish.
Then for the next two months the larval fish live in the currents of the mid water before settling in rocky reef habitats.
Maturity is based on body size rather than age with males reaching maturity around 14 to 19 inches and females around 11 to 18 inches. This normally takes at least 8 years but it depends on ocean conditions.
Tiger rockfish can live for up to at least 116 years!
IUCN Status
Data Deficient
Ecosystem & Cultural Importance
Tiger rockfish are prey for a variety of species including marine mammals, sharks, seabirds and larger fish such as salmon, rockfish, lingcod, and cabezon.
Tiger rockfish are occasionally caught in both commercial and recreational fisheries. Rockfish are included in the federal Groundfish Fishery Management Plan.
Tiger rockfish are found along the Oregon coast. Researchers have seen tiger rockfish in Oregon’s Cascade Head, Redfish Rocks, Cape Falcon and Cape Peretua Marine Reserves.
