The Macha clam (Mesodesma donacium) is a bivalve mollusk native to the sandy coastal shores of South America, particularly along the Pacific coasts. This species is highly valued for its tender, flavorful meat and plays a significant role in local cuisines. The top countries harvesting Macha clams are Chile and Peru, where the species is found in abundance along intertidal zones. In these countries, the Macha clam fishing industry is a vital economic activity for many coastal communities, employing both artisanal and small-scale commercial fishers. Sustainable management practices have become increasingly important due to historical overfishing and habitat degradation, with both Chile and Peru implementing regulations to protect stocks and ensure the long-term viability of this valuable fishery.
