Commercial Fishery & Harvest

In 2023, commercial landings of petrale sole totaled 6.5 million pounds and were valued at $7.7 million, according to the NOAA Fisheries commercial fishing landings database . Gear types, habitat impacts, and bycatch: Bottom trawls are used to catch petrale sole. Trawls that are used to harvest petrale sole can contact the ocean floor and impact habitats, depending on the characteristics of the ocean bottom and the size of the gear. Bottom trawls cause minimal damage to habitat when targeting petrale sole over soft, sandy, or muddy ocean bottoms on the West Coast and Alaska. On the West Coast, NOAA Fisheries and the North Pacific Fishery Management Council have implemented large closed areas to minimize bycatch and protect habitat.
