JAKARTA 22 December 2025 – Green mussel farming (Perna viridis) is one of the marine aquaculture sectors with strong growth potential in Indonesia. Supported by tropical waters and an extensive coastline, green mussels have become a leading seafood commodity with stable market demand for both domestic consumption and the seafood processing industry.
Potential of Green Mussel Farming in Indonesia
As the world’s largest archipelagic country, Indonesia has vast coastal areas that are highly suitable for green mussel cultivation. Several regions, including the northern coast of Java, Lampung, Banten, Sulawesi, and parts of Sumatra, have developed into major production centers. Green mussels are considered a high-value commodity due to their relatively simple cultivation process and the absence of artificial feed requirements.
Site Selection and Environmental Requirements
The success of green mussel farming largely depends on proper site selection. Ideal environmental conditions include:
- Water temperature ranging from 27–32°C
- Salinity levels between 27–35 ppt
- Water depth of 2–10 meters
- Moderate water currents and pollution-free waters
- Adequate plankton availability as a natural food source
Clean and productive waters contribute to high-quality green mussels that are safe for consumption.
Green Mussel Farming Methods
Several farming methods are commonly applied in Indonesia, including:
1. Stake Method
This method uses bamboo or wooden poles planted into the seabed as attachment media for mussel spat. It is widely used due to its low investment cost and ease of application for small- to medium-scale farmers.
2. Floating Raft Method
Floating rafts are constructed from bamboo or pipes that remain afloat on the water surface, equipped with ropes or nets as attachment substrates. This method is suitable for deeper waters and can produce higher yields.
3. Longline Method
The longline method utilizes long horizontal ropes supported by buoys. It is commonly applied in large-scale operations due to its efficiency and uniform growth results.
Spat Collection and Maintenance
Green mussel seeds are naturally obtained from spat that attach to farming media. During the grow-out period, mussels do not require supplementary feed, as they rely on naturally occurring plankton in the water. Maintenance activities include:
- Cleaning the culture media from fouling organisms
- Regular monitoring of water quality
- Managing stocking density to ensure optimal growth
Harvesting and Production
Green mussels can be harvested after 6–8 months of cultivation. Market-size mussels typically reach a shell length of 6–8 cm with thick and high-quality meat. Harvesting is carried out by lifting the culture media and separating the mussels from poles or ropes.
Advantages of Green Mussel Farming
Green mussel farming offers several advantages, including:
- Low production costs
- No artificial feed requirements
- Environmentally friendly practices
- High and consistent market demand
- Suitable for coastal community development
Conclusion
Green mussel farming presents a promising and sustainable marine aquaculture opportunity. With proper site selection and effective management, this commodity can significantly contribute to coastal economic development while supporting national food security.
