The Pacific calico scallop (Argopecten ventricosus) is a medium-sized bivalve mollusk found along the Pacific coasts of the Americas, particularly from Baja California, Mexico, to Peru. Known for its attractive, fan-shaped shell and sweet, tender meat, this species supports a significant regional fishery. The top Pacific calico scallop fishing countries are Mexico and Peru, with Mexico being the largest producer due to extensive natural beds and a well-developed aquaculture sector, especially in the Gulf of California. Peru also harvests this species, primarily from wild populations and increasingly through aquaculture. Both countries export calico scallops to international markets, mainly the United States and Europe, contributing to local economies and providing employment in coastal communities. The industry faces challenges such as overfishing, environmental changes, and the need for sustainable management practices to ensure long-term viability.
