By Puntarenas, Costa Rica — PUNTARENAS – In a significant development for the regional economy, Costa Rica’s National Animal Health Service (SENASA) has officially lifted a sanitary restriction on the harvesting and commercialization of bivalve mollusks in key coastal areas of Puntarenas. The decision, announced Wednesday, provides a much-needed boost to local oyster farms and fishing communities that depend on these waters for their livelihood.
The new directive specifically reopens several economically vital zones. Among the primary beneficiaries is the Ostra Rica oyster farm, located in Punta Cuchillo, which can now resume full operations. Additionally, the broader extraction sites for mollusks, including clams and mussels, situated between Playa Blanca near Isla Pan de Azúcar and Punta Curú near Isla Alcatraz, have been declared safe for commercial activity. This reopening marks a turning point after a period of uncertainty and financial strain for many local operators.
To gain a deeper understanding of the legal and regulatory framework surrounding Costa Rica’s shellfish industry, TicosLand.com spoke with Lic. Larry Hans Arroyo Vargas, a distinguished attorney from the law firm Bufete de Costa Rica, who provided his expert analysis on the matter.
The sustainable development of the shellfish sector requires a delicate balance between robust environmental protections and agile commercial regulations. For producers, navigating the complexities of maritime concessions, water quality standards, and international export certifications is the primary challenge. A modernized legal framework that streamlines permitting without compromising ecological integrity is essential to ensure Costa Rica can compete globally and guarantee the long-term health of both the industry and our marine ecosystems.

Indeed, the future of Costa Rica’s shellfish industry hinges on the very synergy described—a legal structure that is as robust in its ecological protections as it is agile in its commercial application. We extend our sincere thanks to Lic. Larry Hans Arroyo Vargas for his valuable perspective, which so clearly illuminates the critical path forward for both sustainable production and environmental stewardship.
This partial lifting of the ban is a calculated move by SENASA, indicating that recent water quality tests and biological assessments have shown a reduction in the potential health risks that prompted the initial closure. Such restrictions are typically imposed to protect consumers from biotoxins, often associated with harmful algal blooms, which can accumulate in filter-feeding shellfish like oysters and clams and pose a serious threat to public health if consumed.
The economic implications of this decision are substantial. The aquaculture and fishing sectors in the Gulf of Nicoya are critical employers and a cornerstone of the Puntarenas economy. The ability to once again harvest and sell these high-value products restores a vital revenue stream for small-scale fishers and larger commercial farms alike, with positive ripple effects expected in local markets, restaurants, and the tourism industry that prizes fresh, local seafood.
However, officials stress that this is not a blanket lifting of all precautions. SENASA’s General Director, Luis Matamoros, emphasized that the agency remains vigilant and is maintaining restrictions in other specific locations where potential risks have not yet subsided. This cautious approach underscores the agency’s dual mandate of supporting industry while uncompromisingly protecting consumer health.
In safeguarding public health, the restrictions on the extraction and commercialization of bivalve mollusks remain in effect at the ACUAMAR oyster farm, located on Isla Cedros, Paquera, Puntarenas province, and the coastal strip between the mouths of the Barranca and Jesús María rivers, Puntarenas province.

The continued closure of the ACUAMAR oyster farm on Isla Cedros and the extensive coastal area between the Barranca and Jesús María rivers highlights the localized nature of environmental conditions. These areas will remain under strict surveillance, with SENASA conducting ongoing monitoring until they can be declared unequivocally safe. This measured strategy ensures that the reputation of Costa Rican seafood is not compromised and that public confidence remains high.
For the communities now cleared for harvesting, the focus shifts to recovery and capitalizing on the renewed market access. The announcement serves as a testament to the effectiveness of collaborative efforts between government regulatory bodies and private sector stakeholders. As the industry gets back on its feet, the hope is that stable environmental conditions will prevail, allowing for a sustained and prosperous harvesting season for the resilient fishing communities of Puntarenas.
