Commercial red sea urchin landings

Orford reef

Landings history:

Red sea urchins, Mesocentrotus franciscanus, have been commercially harvested in Oregon since 1986. Landing peaked in 1990, when more than 9 million pounds were landed. Since the boom then bust of this new fishery on a virgin stock, the past ~20 years have been charecterized by rather stable landings of around a half million pounds per year (Figure 1). Red sea urchins are Oregon's most valuable dive fishery and the third most valuable shellfish fishery, distantly behind Dungeness crab and pink shrimp.

Harvest locations:

Red sea urchins are harvested exclusively from kelp beds. 90% of Oregon's kelp beds occur south of Charleston, where about that amount of harvest occurs (Figure 2). By far the most important harvest areas are Oregon's two large offshore reefs; Port Orford reef just northwest of Port Orford, OR (~50% of harvest) and Rogue reef, just Northwest of Gold Beach, OR (~25% of harvest). Nearshore areas of Brookings, Port Orford, Charleston and Depoe Bay account of the remaining 25% of harvest.
