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 colder climates.
• Anchoring System: Concrete blocks (dead weights) ranging from 500kg to 1 ton, depending on the depth and current intensity.

 

II. Sanitary Certification for EU Export

Exporting live or processed bivalves to the EU is strictly regulated under Regulation (EU) 2017/625. To enter this market, Venezuela must maintain specific standards:

1. Classification of Production Areas:

1.            Waters must be classified as Class A (direct human consumption) or Class B (requires purification/depuration).

2.            Continuous monitoring for E. coli and Salmonella is mandatory.

2. Biotoxin Control (Red Tides):

1.            Venezuela’s INSOPESCA must provide weekly certificates ensuring the absence of:

• PSP (Paralytic Shellfish Poison).

• DSP (Diarrhetic Shellfish Poison).

• ASP (Amnesic Shellfish Poison).

3. Chemical Contaminants:

1.            Laboratory tests must prove levels of heavy metals (Lead, Cadmium, Mercury) are below EU safety limits.

4. Traceability & Labeling:

1.            Each batch must have a Health Mark (oval stamp) identifying the establishment of origin and the official approval number.

2.            Labels must include the scientific name, production method (aquaculture), and the "best before" date.

5. Audit by DG SANTE:

1.            Exporting companies must be on the "Third Country List" approved by the European Commission, requiring an audit of the Venezuelan sanitary authority's oversight capabilities.

 

III. Pro-Investment Strategy 2026

Investors are currently focusing on Integrated Multi-Trophic Aquaculture (IMTA), where bivalve long-lines are placed near shrimp farms to naturally filter the water, creating a sustainable "circular" production model that is highly valued in the European market.
