Introduction:

Illegal trade in sea cucumbers presents a distinctive transnational wildlife-enforcement challenge. The problem is not confined to illegal harvesting in Indian waters; it extends to the subsequent movement, processing, documentation and possible re-export of the illegally sourced specimens through neighbouring jurisdictions. The India–Sri Lanka maritime corridor is particularly significant because the two countries apply materially different legal and regulatory regimes to sea cucumbers.

The central enforcement concern is therefore provenance laundering: whether illegally harvested sea cucumbers can acquire an apparently lawful commercial identity after crossing the international boundary. Effective enforcement consequently requires not merely stronger border controls, but interoperability of laws, documentation, intelligence and evidentiary systems.

Evidence of the India–Sri Lanka Route:

The most detailed open-source evidence is contained in the Wildlife Conservation Society–India (WCS-India) report, “Illegal Trade of Marine Species in India: 2015–2021”. Based on 187 media-reported marine-wildlife seizure incidents, the report identified 122 incidents involving sea cucumbers, making them the most frequently seized marine wildlife during the study period. Further, media-based data substantially underestimate the actual scale of illegal trade.

More significantly, of the 122 sea-cucumber incidents, 34 contained information concerning attempted international movement. Sri Lanka appeared in 26 incidents, China in six and Malaysia in two. The consignments intended for Sri Lanka originated from Tamil Nadu in 24 incidents and Lakshadweep in two. WCS-India records Sri Lanka as the most frequently identified international location and notes that it was generally an intended transit location for further movement towards Southeast Asian markets.

The scale of the underlying trade is further demonstrated by TRAFFIC and WWF-India's “In Deep Water: India's Sea Cucumbers in Illegal Wildlife Trade (2022)”. As per this Report, Tamil Nadu accounted for the largest number of seizures, followed by Lakshadweep and the Andaman and Nicobar Islands. The TRAFFIC/WWF-India study independently concluded that Sri Lanka, China, and Southeast Asia constitute the top three primary global destinations for sea cucumbers illegally trafficked out of India.

Divergent Legal Frameworks:

India has adopted an exceptionally stringent approach. All sea cucumbers are protected under the Wild Life (Protection) Act, 1972, and their collection and trade are prohibited. Sri Lanka, by contrast, permits regulated exploitation and has developed legitimate sea-cucumber fisheries, aquaculture, processing and export activities. This difference is not, in itself, evidence of illegality in Sri Lankan trade. It nevertheless creates a regulatory asymmetry capable of being exploited when the provenance of individual consignments cannot be independently verified.

The Basel Institute on Governance provides unusually direct analytical support for this proposition. Its Wildlife Crime – Understanding Risks, Avenues for Action: Part 4 – Corruption in Marine Wildlife Trafficking, expressly identifies the India–Sri Lanka sea-cucumber route. It describes poaching in southern India, movement by small boats directly to Sri Lanka, and the potential use of Sri Lanka's marine-products export sector to mix illegally sourced sea cucumbers with legitimate shipments.

The Basel Institute's broader analysis in Marine Wildlife Trafficking Supply Chain explains that where legal and illegal markets operate alongside each other, illicit wildlife can be incorporated into legitimate commercial supply chains. It identifies processors, traders, trans-shippers and exporters as potential points of vulnerability.

Why Sri Lanka May Function as a Transit and Laundering Jurisdiction:

If the ultimate consumer markets are predominantly in East and Southeast Asia, the critical question is why illegally harvested Indian sea cucumbers would be moved through Sri Lanka.

The answer lies principally in commercial and regulatory opportunity. Sri Lanka has an established marine-products sector and legitimate sea-cucumber production and export activities. A jurisdiction possessing legitimate trade in the same commodity can provide opportunities for commingling, documentary substitution or misrepresentation of origin. The Basel Institute specifically observes that species such as sea cucumbers may be smuggled into jurisdictions from which they can subsequently be exported and mislabelled as legitimate products.

Thus, the India–Sri Lanka route should be examined not merely as a smuggling corridor but as a potential provenance-transformation corridor. The relevant enforcement question is not simply whether a consignment is physically present in Sri Lanka, but whether its claimed Sri Lankan origin can be substantiated through an auditable chain of harvesting, landing, processing and export records.

This distinction is essential. Legitimate Sri Lankan sea-cucumber production and exports should not be equated with laundering. The legal concern arises where illegally sourced Indian specimens are introduced into, or represented as part of, a legitimate Sri Lankan supply chain.

Enforcement and Legal Cooperation:

The principal vulnerability is therefore not necessarily legislative absence but inadequate legal interoperability. The United Nations Office on Drugs and Crime (UNODC), in its Wildlife and Forest Crime Analytic Toolkit, identifies differences in national legal and procedural systems, weaknesses in border controls and inadequate cross-border cooperation as important impediments to combating wildlife crime. The Toolkit emphasises inter-agency cooperation and effective cross-border collaboration as components of an effective criminal-justice response.

India and Sri Lanka should accordingly consider a dedicated sea-cucumber enforcement mechanism incorporating five elements. First is provenance verification. Every legitimate export consignment should be capable of being linked to an identifiable source—wild harvest or aquaculture—with corresponding harvesting, landing, processing and export records. Second is bilateral intelligence exchange. Enforcement agencies should routinely exchange information concerning suspected traffickers, vessels, landing sites, processors, exporters, recurring routes and modus operandi. Third is cross-border documentary verification. Where Indian intelligence indicates that a Sri Lankan consignment may contain Indian-origin sea cucumbers, a rapid mechanism should exist for verification of its declared provenance before export. Fourth is coordinated investigations. Cases involving cross-border trafficking should be capable of progressing through mutual legal assistance, evidence sharing and, where legally permissible, coordinated or joint investigations. Fifth is supply-chain controls. Enforcement should extend beyond fishermen and couriers to processors, warehouses, exporters, financiers and other commercial actors capable of introducing illicit material into legitimate trade.

Conclusion:

The India–Sri Lanka sea-cucumber problem demonstrates that legal divergence becomes an enforcement vulnerability when it is not accompanied by mechanisms for cross-border verification of provenance. The objective should therefore not necessarily be identical legislation in both countries. It should be interoperable enforcement: a system under which the legal identity of wildlife remains traceable after crossing a border. The governing principle should be clear: an international boundary must not become a mechanism for converting illegally sourced wildlife into apparently legitimate wildlife.
