Bihar Warns Against Unknown Fish Carried By Nepal Floodwaters
Floods from Nepal have carried water and fish into parts of Bihar.
Some fish are appearing in places where people do not usually see them.
Bihar officials say people should not catch, buy, sell, or eat fish from floodwaters.
Floodwater can mix with sewage, dead animals, dirty drains, and other harmful materials.
This can put dangerous germs on or in the fish.
Some people were reportedly sick after eating the fish, although the reports are described as alleged.
Videos showed very large catfish near the Gandak River.
An expert said many may be goonch catfish, which can spoil quickly after dying.
People should report unusual fish and get medical help if they feel sick after eating them.
Bihar authorities advised residents not to catch, buy, sell, or eat unidentified fish carried into the state by Nepal floodwaters.
The warning followed reports of unfamiliar fish in flood-affected areas and alleged illnesses after some people consumed them.
Officials said floodwater can expose fish to sewage, open drains, dead animals, decaying matter, bacteria, viruses, fungi, and other pathogens.
Videos showed unusually large catfish near the Gandak River; wildlife expert Sameer Kumar Sinha said many may be goonch catfish.
Residents were told to report unusual fish, ignore rumours, and seek medical care for vomiting, diarrhoea, stomach pain, dizziness, or breathing difficulty.

Official Safety Warning
Possible Species Identification
Whether the fish should be eaten
Official Safety Warning
Bihar authorities and Nepal police urged people to avoid unfamiliar fish and fish caught from floodwaters until they are identified and declared safe.
Possible Species Identification
Sameer Kumar Sinha said many fish seen near the Gandak may be Bagarius bagarius, or goonch catfish, a species consumed by local communities; he still supported caution because the fish can spoil quickly after death.
Source of the health risk
Official Safety Warning
Officials attributed the danger to possible contamination from floodwater, including sewage, dead animals, decaying matter, bacteria, viruses, fungi, and other pathogens.
Possible Species Identification
The expert view suggests the fish may be a known species rather than inherently unfamiliar or unsafe, but polluted water and rapid spoilage could still create health risks.

- Bihar’s Department of Dairy, Animal and Fisheries Resources, including its Fisheries Division.
- Floodwater route
- Reports said water from Nepal’s Trishuli River was flowing into Bihar through the Gandak and Kosi rivers.
- Main restriction
- Residents were told not to catch, buy, sell, or consume unidentified fish or fish caught directly from floodwaters until conditions return to normal and the fish are cleared as safe.
- Reported fish
- Videos showed unusually large catfish near the Gandak River. Sameer Kumar Sinha said many may be Bagarius bagarius, commonly called goonch catfish or locally called Gochita.
- Contamination risks
- Officials cited possible contact with sewage, open drains, dead animals, decaying matter, bacteria, viruses, fungi, and other pathogens.
- Symptoms requiring care
