Technical Specifications for the long-line cultivation system used in Venezuela and the specific Sanitary Requirements for exporting bivalves to the European Union (EU) as of 2026.
I. Technical Specifications: Long-Line System (Mussels/Oysters) The "Long-Line" (linea larga) is the preferred method in Venezuela, especially in the Gulf of Cariaco , due to its resistance to currents and efficiency in open waters. Main Line (Mother Line): A high-density polyethylene (HDPE) or polypropylene rope, usually 100 to 150 meters long, anchored at both ends. Buoyancy: 20 to 50-liter plastic buoys spaced every 2 to 3 meters. In 2026, many farms are transitioning to UV-resistant recycled buoys to reduce microplastic pollution. Cultivation Ropes (Droppers): 5 to 8-meter vertical ropes where seeds are attached. Density: Approximately 150 to 200 mussels per meter . Growth Rate: Due to warm waters (26°C - 29°C), Perna perna reaches commercial size (7–8 cm) in just 6 to 8 months , significantly faster than in col...
