Advisory Issued After Unusual Fish Appear in Floodwaters

As floodwaters from Nepal continue to spread across parts of Bihar's Gandak basin, the state government has cautioned residents against eating or selling unfamiliar fish found in inundated areas. The fisheries division of Bihar's dairy, fisheries and animal resources department issued the advisory on Tuesday, following reports of unidentified and unusual-looking fish surfacing in floodwaters, local water bodies and low-lying areas of West Champaran and Gopalganj.

The advisory, reported by CNBC TV18 and The Times of India, asks people to avoid consuming or selling such fish until they are properly identified. The department stated that information had been received about the arrival of unusual fish in some areas of Bihar alongside the floodwaters from Nepal. Officials said flooding can carry fish far from their natural habitats, sweeping them out of rivers, ponds and other water bodies. In the process, the fish may pass through heavily contaminated water and come into contact with drains, animal carcasses and other pollutants, increasing the risk of bacterial, viral and fungal contamination.

Department Warns of Potential Health Risks

The department warned that some unusual fish may be harmful to human health if consumed, as they could carry viruses, bacteria, fungi and other harmful organisms. The advisory explicitly states: "Do not consume any unidentified or unusual-looking fish. Until confirmation by the concerned department, an unfamiliar fish should not be considered fit for consumption." Authorities also cautioned residents against identifying a fish as edible merely because it resembles a commonly consumed species.

Residents have been advised to report any sightings of such fish to the district fisheries officer or local administration. People who develop symptoms such as vomiting, diarrhoea, stomach pain, dizziness or breathing problems after eating fish from flood-hit areas have been advised to seek medical help immediately.

Expert Identifies Likely Species

Wildlife Trust of India director Sameer Kumar Sinha said most of the unusual fish reported in the Gandak following the Nepal floods are believed to be Bagarius bagarius, popularly known as the goonch catfish and locally called "Gochita". The species is a large freshwater catfish found in fast-flowing rivers in India, Nepal and parts of Southeast Asia. It is carnivorous, feeding on smaller fish, crabs and other aquatic organisms, and typically inhabits deep, rocky stretches of rivers. The goonch catfish is listed as a threatened species by the International Union for Conservation of Nature.

What was claimed, and who backed it

AI-extracted; can misattribute a claim — see Methodology.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting that specific claim — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
