Speaking at the inauguration of a scientist–farmer interface programme to mark National Fish Farmers Day at CMFRI on 10 July, CMFRI director Grinson George warned that the warming associated with El Niño is expected to intensify between October and December. The resulting impact is likely to be felt across the northern Indian Ocean by April or May 2027.
“Oil sardine stock is abundant this year, but the resource is likely to be affected in 2027 if the projected warming occurs. Small pelagic fishes, especially oil sardine, are the most vulnerable species to heatwaves and ocean warming,”said Dr George in a press release, adding that it would lead to reduction in overall marine fish production.
Highlighting the possible El Nino impact, he said: “Established information indicate probability of marine heatwaves, increased sea surface temperature and high salinity during April and May in 2027.
He also added that CMFRI would provide El Nino advisories to fishermen and fish farmers during this year itself. Urging fish farmers to brace for the situation, Dr George said sudden rainfall following prolonged periods of high temperature and salinity could also trigger rapid salinity fluctuations, disrupting coastal aquaculture activities.
He stressed the need for continuous monitoring of ocean conditions and adaptive management to minimise the impact of climate-driven changes on marine resources and the livelihoods of fishers and coastal fish farmers.
