Molecular genetic structure suggests limited larval dispersal in grass rockfish, Sebastes rastrelliger

The grass rockfish (Sebastes rastrelliger Jordan and Gilbert, 1880) is a non-migratory, benthic, near shore species distributed along rocky reefs and sea grass beds. It occurs from Baja California, Mexico, to Oregon, USA, spanning the Oregonian and Californian biogeographic provinces. In California this fish receives intense fishing pressure from an expanding and loosely regulated live-fish fishery. It is not known whether or by what mechanism...
