Argopecten purpuratus
Edible scallop native to South American west coast bays.
Argopecten purpuratus is a saltwater bivalve mollusk from the Pectinidae family, harvested for food. Its natural range is limited to certain bays along the southern west coast of South America, stretching from Peru to Chile.
In Peru, large natural populations occur in the bays of Pisco (300 km south of Lima), Casma and Samanco (400 km north of Lima), Trujillo (600 km north of Lima), and Sechura Bay and Paita Bay (900 km north of Lima).
These scallops are collected and sold to markets worldwide. In most growing areas, wild harvesting has largely been replaced by aquaculture. This involves restocking natural beds, tending the scallops during their growth period, and harvesting them at the end of the cycle. These practices have helped restore natural banks and maintain sustainable production levels.
The main markets demand different product forms. The United States buys roe-off product. France prefers roe-on product. China purchases roe-on, skirt-on, and whole scallops. Australia and New Zealand also want roe-on product. Spain and Italy buy roe-on scallops on the half shell.

Lore & Background
Argopecten purpuratus is a marine bivalve mollusc in the family Pectinidae, found naturally in certain bays along the southern west coast of South America, from Peru to Chile. In Peru, large natural populations occur in bays including Pisco, Casma y Samanco, Trujillo, and Sechura Bay & Paita Bay. The scallops are harvested and commercialized to several markets worldwide. In most growth areas, harvesting of natural scallops has been replaced by aquaculture operations, which involve re-stocking natural areas, caring for scallops during the grow-out period, and harvesting at the end of the cycle. These practices have allowed natural banks to recover and maintain sustainable production levels.
Reader's Guide
Argopecten purpuratus holds significance as a commercially valuable marine species, harvested and sold to markets including the USA, France, China, Australia and New Zealand, and Spain and Italy. Its demand varies by market: the USA prefers Roe Off product, France prefers Roe-On, China prefers Roe-On & Skirt-On and Whole products, Australia and New Zealand prefer Roe-On, and Spain and Italy prefer Roe-On on Half shell. The shift from harvesting natural scallops to aquaculture operations has been key to sustaining production. Aquaculture involves re-stocking natural areas, managing scallops during the grow-out period, and harvesting at cycle end. This approach has helped natural banks recover and maintain sustainable production levels. The species is thus an example of how managed aquaculture can support both commercial demand and ecological recovery of natural stocks.
