In Context
India, characterized by its vast coastline and abundant inland water resources, has established itself as a prominent player in the global aquaculture sector. Over the last twenty years, the country has achieved significant advancements, particularly in prawn farming, effectively addressing both economic and nutritional objectives.
What is Aquaculture?
Aquaculture refers to the systematic cultivation of aquatic organisms in various environments, including freshwater, brackish water, and marine settings. It serves as a complement to traditional capture fisheries and is essential for satisfying the increasing demand for animal protein, creating job opportunities, and enhancing export revenues.
Aquaculture can be categorized into the following types:
India’s Remarkable Progress in Aquaculture
Currently, India ranks as:
A notable aspect of India’s success in aquaculture is its flourishing black tiger prawn (Penaeus monodon) industry. This high-value species is cultivated in various suitable coastal areas and enjoys strong demand for both local consumption and export markets.
Factors Contributing to India's Significant Growth in Aquaculture
Geographic and Natural Benefits: India boasts a lengthy coastline of 11,098 km and plentiful brackish water areas. The availability of coastal groundwater and tidal influences facilitates the management of water salinity, which is crucial for prawn farming, requiring levels between 10 and 25 g/L.
Innovative Farming Practices: The adoption of smaller ponds, particularly in Andhra Pradesh, enhances yield and disease management. Effective pond management and the balancing of salinity through the mixing of brackish and river water are also key strategies.
Collaboration Between Private and Institutional Sectors: Research initiatives from organizations such as ICAR-CIBA have led to the development of ‘specific pathogen-free’ broodstock. Additionally, the aquafeed industry has expanded, along with laboratories dedicated to disease detection.
Challenges Facing Aquaculture
Disease Outbreaks: Pathogens such as Vibrio harveyi and the White Spot Syndrome Virus can result in annual yield losses of up to 25%.
Environmental and Climate Change Challenges: Variations in salinity, fluctuations in water temperature, and extreme weather conditions disrupt production cycles.
Infrastructure and Resource Limitations: There is a pressing need for enhanced access to testing laboratories, biosecure hatcheries, and cold chain logistics, particularly in remote areas.
Key Government and Research Initiatives
ICAR-CIBA (Central Institute of Brackishwater Aquaculture): This institute is at the forefront of developing specific pathogen-free (SPF) prawns.
The promotion of phage therapy is being explored as a solution to combat bacterial diseases.
Government programs, such as PM Matsya Sampada Yojana, provide skill training, credit access, and support for small-scale farmers.
A network of laboratories and diagnostic services is being established to monitor and manage infections proactively.
