Kerala’s fishing communities are grappling with a deepening crisis as rising sea temperatures drive fish stocks deeper into the ocean, slashing catches and spiking prices. This issue, highlighted in recent reports from Kozhikode and beyond, threatens livelihoods and food security across the state.
Kerala’s 590-km coastline supports over 1.4 million people in the fisheries sector, but summer heatwaves have reduced fishing days from 300 to just 100 annually due to bans, rough weather, and now escalating temperatures. In April 2026, surface waters warmed dramatically, pushing planktons key fish food deeper, causing species like mackerel and sardines to migrate offshore where traditional boats can’t reach. Catches have plummeted across districts like Kollam, Kozhikode, Alappuzha, and Kochi, with over 80% of boats idled for weeks and many retail shops closing.
Experts from the Central Marine Fisheries Research Institute (CMFRI) explain that even minor sea temperature rises alter fish behavior: warmer surface layers deplete near-shore planktons, forcing pelagic fish into deep seas. Dr. V. Kripa notes this “chakara” phenomenon intensifies in summer, contrasting rainy seasons when cooler waters boost coastal abundance. Climate change amplifies this, with Kerala’s early 2026 heat surges signaling broader shifts, as seen in eroded shores like Pozhiyoor where raft fishers now limit outings to dawn hours.
Fish prices have skyrocketed: Indian oil sardines and mackerels hit ₹240-260/kg, ayala (mackeral) ₹240/kg, mathi (sardine) ₹120/kg, and premium varieties like neimeen reaching ₹1,100-1,400/kg or vanishing entirely. Exports dipped as deep-sea boats stayed docked amid heat and manpower shortages, while markets shifted to farmed fish at ₹450/kg. In Kozhikode and Kollam key hubs like Kollam Fishing Bank vendors report massive supply gaps, hurting consumers who rely on affordable seafood for protein.
This crisis echoes past scarcities (2024 onwards) blamed on overfishing, pollution, and foreign trawlers, but 2026’s intensity ties directly to record heat, shrinking reservoirs, and even inland fish deaths in Palakkad. It endangers Kerala’s cultural staple fish in every meal and tourism, as coastal economies falter. Vulnerable groups like women vendors and small-scale fishers face the brunt, underscoring food security risks in a protein-dependent state.
