In Context
- India, with its extensive coastline and inland water resources, has emerged as a global leader in aquaculture. Over the past two decades, India has made remarkable progress, especially in prawn farming, balancing both economic and nutritional goals.
What is Aquaculture?
- Aquaculture involves the controlled cultivation of aquatic species in freshwater, brackish, or marine environments. It complements capture fisheries and plays a pivotal role in meeting the growing demand for animal protein, generating employment, and contributing to exports.
- It can be classified into following categories:
- Freshwater aquaculture
- Coastal aquaculture
- Sea farming
- Brackish water aquaculture
India’s Remarkable Progress in Aquaculture
- India is currently:
- 3rd largest producer of aquaculture products globally.
- 2nd in the world for prawn production.
- Home to key aquaculture states: Andhra Pradesh, West Bengal, Tamil Nadu, Odisha, and Gujarat.
- A highlight of India’s aquaculture success is its thriving black tiger prawn (Penaeus monodon) industry. This high-value species is farmed across suitable coastal regions and is in strong demand for both domestic consumption and export.
Factors Behind India’s High Growth in Aquaculture
- Geographic and Natural Advantages: Long coastline (11,098km) and abundant brackish water zones.
- Coastal groundwater and tidal access aid water salinity control (10–25g/L needed for prawn farming).
- Innovative Farming Techniques: Promotion of smaller ponds (e.g., in Andhra Pradesh) for better yield and disease control.
- Controlled pond management and salinity balancing through brackish water and river water mixing.
- Private and Institutional Collaboration: Research support from institutions like ICAR-CIBA, which developed ‘specific pathogen free’ broodstock.
- Growth of aquafeed industries and labs for disease detection.
Challenges in Aquaculture
- Disease Outbreaks: Pathogens like Vibrio harveyi and White Spot Syndrome Virus cause up to 25% annual yield losses.
- Environmental and Climate Change Pressures: Salinity shifts, water temperature variations, and extreme weather events affecting production cycles.
- Infrastructure and Resource Gaps: Need for improved access to testing labs, biosecure hatcheries, and cold chain logistics in remote regions.
Key Government and Research Initiatives
- ICAR-CIBA (Central Institute of Brackishwater Aquaculture): Pioneering SPF (specific pathogen-free) prawn development.
- Promotion of phage therapy to tackle bacterial diseases.
- Skill training, credit access, and support for small-scale farmers through government schemes like PM Matsya Sampada Yojana.
- Lab networks and diagnostic services to monitor and contain infections early.
Way Ahead
- To sustain the growth and make aquaculture climate-resilient, India needs to:
- Scale biosecure hatcheries and expand SPF broodstock production.
- Encourage R&D in feed efficiency, breeding, and disease resistance.
- Improve cold chain logistics and export infrastructure.
- Promote digital aquaculture management systems for small farmers.
- Integrate environmental sustainability, like mangrove-friendly shrimp farming.
