Prior to 2017, Gulf of Alaska (GOA) rockfish were assessed on a biennial stock assessment schedule to coincide with the availability of new survey data. The new schedule sets full assessments for dusky rockfish in the ‘off’ survey years (even years) and partial assessments for the ‘on’ survey years (odd years).

2017 Alaska Fisheries Science Center Gulf of Alaska Dusky Rockfish Stock Assessment

The National Standard Guidelines for Fishery Management Plans published by the National Marine Fisheries Service (NMFS) require that a stock assessment and fishery evaluation (SAFE) report be prepared and reviewed annually for each fishery management plan (FMP). The SAFE reports are intended to summarize the best available scientific information concerning the past, present, and possible future condition of the stocks and fisheries under federal management. The FMPs for the groundfish fisheries managed by the Council require that drafts of the SAFE reports be produced each year in time for the December North Pacific Fishery Management Council (Council) meetings.

2015 Assessment of the Dusky Rockfish Stock in the Gulf of Alaska

Dusky rockfish (Sebastes variabilis) have one of the most northerly distributions of all rockfish species in the Pacific. They range from southern British Columbia north to the Bering Sea and west to Hokkaido Is., Japan, but appear to be abundant only in the Gulf of Alaska (GOA). The forms of dusky rockfish commonly recognized as “light dusky rockfish” and “dark dusky rockfish” are now officially recognized as two species (Orr and Blackburn 2004). S. ciliatus applies to the dark shallow-water species with a common name dark rockfish, and S. variabilis applies to variably colored usually deeper-water species with the common name dusky rockfish.
