KOCHI, 10 July 2025: In a significant development for India’s aquaculture sector, the ICAR-Central Marine Fisheries Research Institute (CMFRI) has unveiled a revolutionary hatchery technology for the Indian Peacock Mussel (Perna viridis), also known as the green mussel. The innovation is set to transform mussel farming by enabling mass-scale, cost-effective seed production with higher profitability for coastal communities.
The new hatchery protocol supports commercial production of mussel seeds through optimized nursery systems and feed strategies, offering high survival rates and attractive returns for farmers.
Key Highlights of the Technology:
- Mass seed production enabled by precise control over density, feeding, and water circulation.
- Micro nurseries (3–4 mm spat) designed with upwelling/downwelling systems, ensuring uniform growth and settlement.
- Use of a standardized microalgae mix boosts spat development and shortens nursery cycles.
- Field nursery silos produce robust juveniles ready for sea farming.
- Seed survival rate of 25–30?hieved, with a seed cost ranging from 10 to 20 paisa per spat.
Farmers can realize net profits exceeding INR 1,000 per mussel rope, making it a highly viable livelihood option.
A Game-Changer for Coastal Livelihoods
India has long held potential for expanding mussel farming due to its vast coastline and nutrient-rich waters. However, the lack of dependable seed supply has been a bottleneck for scaling operations. This new hatchery model solves a critical gap by enabling year-round seed availability, reducing dependence on wild seed collection, and supporting sustainability.
The technology also aligns with India's Blue Economy strategy, aimed at enhancing ocean-based livelihoods, ensuring nutritional security, and promoting export-ready aquaculture products.
Industry and Scientific Impact
Dr. A. Gopalakrishnan, Director of ICAR-CMFRI, remarked, “This hatchery breakthrough for green mussels is a milestone in India's mariculture journey. It offers a replicable, affordable, and scalable model that can empower thousands of small-scale coastal farmers with new income opportunities.”
The institute is now working with coastal state governments, private hatcheries, and self-help groups (SHGs) to train and transfer the technology across Kerala, Karnataka, Goa, and other key mussel farming zones.
