Authorities in Bihar advise residents not to catch, buy, sell, or consume unusual or unidentified fish reported in flood-affected areas following flash flooding in Nepal and the subsequent rise of rivers in Bihar. Multiple outlets report that people in districts along the Gandak river and floodplains have found “strange-looking” fish, prompting the state to issue a cautionary advisory.
The Bihar government links the concern to flood-driven movement of aquatic species across borders and the possibility that fish may come into contact with contamination. Officials say floodwaters can carry fish into locations where they do not normally occur and may expose them to polluted material, including sewage or dead organic matter, increasing risks of infections or other illness. Outlets also note that the government advises reporting sightings to fisheries officials.
While coverage broadly agrees on the health warning, some outlets add details on symptoms to watch for, and others cite expert suspicion that at least some fish may be goonch catfish, which can deteriorate quickly after being caught. Reporting varies by emphasis—some focus on the advisories against consumption and trading, while others highlight the possible sources of contamination and the need to seek medical care if illness occurs.
