A sudden surge of juvenile Indian Oil sardines along Kerala’s coast in 2024 was driven by climate-induced monsoon trends according to a new study by the ICAR-Central Marine Fisheries Research Institute
Published in the journal Current Science, the study links the unprecedented influx of juvenile sardines to monsoon rainfall and nutrient-rich upwelling, which spurred a bloom of microplankton, the primary food source for sardine larvae.
The result was a spike in larval survival and a surge in sardine recruitment.
