Description

The Yellowmouth Rockfish is one of more than 35 rockfish species occurring in marine waters along the coast of British Columbia. It is similar to the Pacific Ocean Perch, and prior to the mid–1970s, both species were classified as “red rockfish” or “ocean perch”. Adults are primarily red, with black mottling on their backs, and the species is distinguished from other rockfish by characteristic yellow, red and black markings in its mouth.

Habitat

Yellowmouth Rockfish occur at depths of 100–430 m along the continental slope. Their range extends from the northern Gulf of Alaska to northern California. The species is most abundant between southeastern Alaska and Oregon, and in British Columbia the apparent area of highest concentration is in Queen Charlotte Sound. The area of occupancy of Yellowmouth Rockfish in Canadian waters is estimated to be 11,000 – 34,000 km2.

Based on the species’ apparent depth and substrate preferences, approximately 48,000 km2 of potential habitat is estimated to exist for Yellowmouth Rockfish in Canada.

Threats

Commercial fishing is the primary threat to Yellowmouth Rockfish. The species is caught mainly by bottom and mid–water trawls in British Columbia. Rockfish life history traits of slow growth, delayed maturity and longevity potentially make these fish vulnerable to overfishing, habitat loss from bottom trawling and adverse environmental changes.

Further Information

Several achievements contributing to the recovery of the species have been realized in recent years. Current management of the Yellowmouth fishery includes Individual Tradable Quotas (ITQs) and Total Allowable Catch (TAC), guided by scientific advice and the Sustainable Fisheries Framework (SFF). All vessels have mandatory 100% at-sea and dockside monitoring and accountability for all released and retained rockfish catch.

Fisheries protection and pollution prevention provisions of the Fisheries Act provide protection to this species. Yellowmouth likely receive partial protection from rockfish conservation areas and prohibitions on trawling in sections of their range.
