Authorities Flag Ecological Risk as Illegal Magur Fish Movement Detected in East Sikkim

The Fisheries Department, Pakyong District has stepped up monitoring and field action after detecting repeated violations linked to illegal fish imports and the sale of banned species across parts of East Sikkim.

Officials said intensified checks at Rangpo—Sikkim’s main entry point—led to the detection of undeclared fish consignments and the illegal movement of live Thai Magur. Night-time inspections of fish-transport vehicles were carried out to track supply routes and verify whether consignments met safety and regulatory standards.

Thai Magur (Clarias gariepinus), an invasive species prohibited under government guidelines, remains banned due to its impact on native aquatic life. The department noted that unauthorised trade in such species not only undermines biodiversity but also carries food safety concerns and revenue losses for the state.

Parallel inspections were conducted at fish vending points in Rangpo, Majhitar, Singtam, IBM and nearby areas. Vendors operating without valid approvals were instructed to regularise documentation, while outlets found selling banned Magur species faced seizure and safe disposal of stock. Officials reiterated compliance requirements related to hygiene, storage, icing and waste handling.

The department also highlighted a recurring concern where live Magur fish are purchased for ritual release during religious observances. Authorities cautioned that releasing invasive species into rivers disrupts fragile ecosystems and harms indigenous fish populations. To address this, awareness efforts are being reinforced, and locally available native species such as Katley and Bhitti are being promoted as alternatives for ceremonial purposes.

River patrols were carried out in coordination with local protection committees across stretches including Rangpo, Reshi Khola, Rorathang, Kumrek and surrounding areas. While some cases of unlicensed fishing and gill net use were identified, officials observed improved compliance in other zones, along with visible recovery of native fish species—an indication that conservation measures are beginning to show results.
