Defining blue revolution, explain the problems and strategies for pisciculture development in India.

Blue Revolution defined

The Blue Revolution refers to the rapid, science-led expansion of fish production through inland aquaculture and marine fisheries, conceived as a counterpart to the Green Revolution in crops. In India it evolved from the Fish Farmers' Development Agencies of the 1970s to the Neel Kranti Mission (2015-16) and the Pradhan Mantri Matsya Sampada Yojana (PMMSY, 2020). India is today the world's second-largest fish producer, contributing about 8% of global output, is the largest producer in inland aquaculture, and its fisheries support nearly 30 million livelihoods while earning substantial seafood export revenue.

Problems in pisciculture

• Overexploitation of marine stocks, falling catch per unit effort, and illegal, unreported and unregulated fishing.
• Poor-quality seed and feed, disease outbreaks, and low productivity in fragmented, unorganised inland farms.
• Weak cold chains and post-harvest losses of 10-15%, which erode incomes and export value.
• Water pollution, eutrophication and expanding oceanic dead zones; mangrove destruction from unregulated shrimp culture.
• Inadequate credit and insurance for small fishers, and rising vulnerability to cyclones and climate change.

Strategies

• PMMSY and the Fisheries and Aquaculture Infrastructure Development Fund (FIDF) to build harbours, hatcheries and cold chains.
• Modern techniques - cage culture, biofloc, recirculatory aquaculture systems, and brackish-water and seaweed farming.
• Genetically improved breeds such as Jayanti Rohu and GIFT tilapia; Kisan Credit Cards and Sagar Mitras for fishers.
• Ecosystem-based, sustainable management, deep-sea fishing fleets, and MPEDA-led branding to grow seafood exports.
• A supportive policy and regulatory framework, e-markets for better price realisation, and skilling of fishers and self-help groups.

A durable Blue Revolution must marry higher output with ecological sustainability and the welfare of traditional fishing communities, so that growth in production does not come at the cost of fragile coastal ecosystems or of small fishers' livelihoods.
