NEW DELHI: Hundreds, possibly thousands, of dead fish were found along the banks of the Yamuna near Burari in north Delhi, raising fresh concerns over the river’s water quality and the health of its aquatic ecosystem, the New Delhi Nature Society said on Thursday.The society, which describes itself as a “A collective of individuals. Spreading awareness…” on its X profile, shared photographs and videos on Wednesday evening showing dead fish along the riverbank.“Specific cause not established. Locals allege chemical waste discharged from Haryana through canals. Could it be related to the acid rain on Oct 12th?” it said in a post on X.According to the society, fish deaths can indicate ecological stress, including deteriorating water quality, low levels of dissolved oxygen and the presence of toxic substances.The cause of the latest fish deaths remains unclear.The visuals have emerged amid continued concerns over pollution in the Yamuna, which continues to face pollution-related challenges despite repeated efforts to clean the river.Mass fish deaths were also reported from Burari in May last year. At the time, visuals showed thousands of dead fish floating in the river, with locals attributing the deaths to chemical waste allegedly discharged from Haryana. Reports had also pointed to high pollution levels.In May this year, hundreds of fish died at Sanjay Lake in east Delhi amid a heatwave and falling water levels. Experts had cited a combination of high temperatures, concentrated pollutants and declining dissolved oxygen levels as possible factors.(With inputs from PTI)
