Fishermen Disputes — Basic Structure

Updated 5 Mar 2026

Basic Structure

The India-Sri Lanka fishermen disputes represent a persistent bilateral challenge centered on fishing activities in the Palk Bay and Gulf of Mannar. The core issue stems from the 1974 maritime boundary agreement where India ceded Katchatheevu Island to Sri Lanka, establishing the International Maritime Boundary Line (IMBL) that runs through traditional fishing grounds.

Indian fishermen, primarily from Tamil Nadu, frequently cross into Sri Lankan waters due to depleted fish stocks in Indian territory, leading to arrests, boat seizures, and diplomatic tensions. The dispute involves multiple dimensions: legal (maritime boundary interpretation), economic (livelihood of fishing communities), environmental (sustainable fishing practices), and political (domestic pressures in both countries).

Key stakeholders include fishing communities, state governments, naval authorities, and diplomatic establishments. The Sri Lankan Navy arrests 50-150 Indian fishermen annually for territorial violations and using banned fishing methods like bottom trawling.

Bilateral mechanisms include the Joint Working Group on Fisheries (established 2008) and High-Level Committee meetings, but progress remains limited. Recent developments (2020-2024) show continued arrests despite diplomatic efforts, with over 100 fishermen detained in 2023.

The issue impacts broader India-Sri Lanka relations and tests India's neighborhood policy effectiveness. For UPSC, this topic is crucial for understanding bilateral relations, maritime boundaries, Centre-State dynamics in foreign policy, and the intersection of local issues with international diplomacy.

Fishermen Disputes vs India-Bangladesh Fishermen Issues
Open India-Bangladesh Fishermen Issues
AspectFishermen DisputesIndia-Bangladesh Fishermen Issues
Geographic ScopePalk Bay and Gulf of Mannar - narrow water bodies with overlapping fishing zonesBay of Bengal - larger maritime area with clearer territorial demarcation
Historical Context1974 Katchatheevu cession created new boundaries through traditional fishing groundsPost-1971 boundary settlement with less impact on traditional fishing patterns
Frequency of Incidents100+ arrests annually with regular boat seizures and diplomatic interventionsFewer incidents, mostly related to inadvertent crossings during rough weather
Bilateral MechanismsDedicated Joint Working Group on Fisheries with regular meetingsAddressed through broader bilateral consultations and border management meetings
Political SensitivityHigh political sensitivity in Tamil Nadu with electoral implicationsLower political profile with less domestic political pressure

The India-Sri Lanka fishermen disputes are more intense and politically sensitive compared to India-Bangladesh issues due to the narrow Palk Bay geography, historical Katchatheevu cession, and higher frequency of arrests. The Sri Lanka dispute has dedicated bilateral mechanisms and greater domestic political implications, particularly in Tamil Nadu, while Bangladesh issues are less frequent and handled through routine diplomatic channels.

Why it is tested: UPSC often compares different bilateral disputes to test understanding of India's neighborhood challenges. Questions may ask about the varying intensity and management approaches for different maritime disputes.

Fishermen Disputes vs India-Pakistan Sir Creek Dispute
AspectFishermen DisputesIndia-Pakistan Sir Creek Dispute
Nature of DisputePrimarily livelihood-based conflict over fishing rights with established boundariesTerritorial dispute over boundary demarcation in Sir Creek area
Resolution MechanismsActive bilateral engagement through Joint Working Groups and diplomatic channelsStalled negotiations with limited progress due to broader India-Pakistan tensions
Impact on RelationsManageable irritant that doesn't derail broader bilateral cooperationPart of larger complex of disputes affecting overall bilateral relationship
International LawOperates within accepted UNCLOS framework with established maritime boundariesInvolves interpretation of colonial-era agreements and boundary demarcation principles
Stakeholder InvolvementFishing communities, state governments, and diplomatic establishments actively engagedPrimarily handled at government level with limited community involvement

The India-Sri Lanka fishermen dispute is a livelihood-based conflict within established boundaries that allows for active bilateral management, while the Sir Creek dispute is a territorial boundary issue complicated by broader India-Pakistan tensions. The fishermen dispute has more stakeholder involvement and regular diplomatic engagement, whereas Sir Creek remains largely unresolved due to political complexities.

Why it is tested: This comparison helps understand different types of maritime disputes - livelihood vs territorial - and their varying resolution prospects. UPSC may test understanding of how bilateral relationship quality affects dispute resolution mechanisms.
