1. Coastal Aquaculture Authority vs. Union of India (2004)
Facts
The Coastal Aquaculture Authority (CAA) filed a petition against several shrimp farms in Tamil Nadu and Andhra Pradesh engaging in unregulated fishing practices, leading to depletion of fish stocks and damage to coastal ecosystems.
Issue

Judgment
The Supreme Court held that overexploitation of marine resources violates the Environment Protection Act, 1986, and directed:
Regulation of shrimp farming
Implementation of seasonal fishing bans
Protection of mangroves and breeding grounds
Principle
Overfishing is an environmental offense.
Courts enforce sustainable use of marine resources to protect livelihoods and biodiversity.
2. T.N. Godavarman Thirumulpad vs. Union of India (1996 onwards)
Facts
Though primarily a forest case, this PIL included issues of illegal fishing in rivers and estuaries, affecting endangered fish species.
Issue
Does unsustainable fishing in public water bodies constitute an ecological and legal violation?
Judgment
The Supreme Court expanded the public trust doctrine to water bodies and fisheries, holding that:
State authorities must prevent overfishing and illegal capture
Enforcement must include restrictions on size, season, and methods of fishing
Principle
Water bodies are public trust resources, and overfishing is actionable under environmental and criminal law.
Courts have a proactive role in resource conservation.
3. M.C. Mehta vs. Union of India – Ganga Pollution & Fisheries (1988)
Facts
Fishermen complained that industrial effluents and excessive mechanized fishing in the Ganga led to fish population collapse.
Issue

Judgment
The Supreme Court ruled that:
Pollution and overfishing jointly threaten fish stocks and livelihoods
State authorities must enforce fisheries management, seasonal bans, and monitoring
Principle
Overfishing is not just an economic issue but also a public safety and livelihood concern.
Courts can mandate preventive and corrective actions.
