Marine Heatwaves and Warming Threaten Fisheries, Scientists Say at CMFRI Symposium

Marine scientists warned that warming seas and frequent marine heatwaves are putting fisheries and coastal livelihoods at risk. Speaking at a symposium on Societal Applications in Fisheries and Aquaculture using Remote Sensing Imagery hosted by the Central Marine Fisheries Research Institute in Kochi, they highlighted additional threats such as shifting fish populations, coral bleaching, algal blooms and unpredictable ocean conditions. The event drew about 300 participants representing 30 countries, including fisheries scientists, climate experts, remote‑sensing specialists and oceanographers. Delegates stressed the need to combine satellite remote sensing, oceanographic observations, climate models, artificial intelligence and in‑situ data to track physical and biological changes in marine ecosystems. They argued that such integrated monitoring can improve timely advisories and early‑warning systems for fishers and coastal communities. ## Context Marine heatwaves are short periods of unusually high sea temperature that can stress or kill marine life. Satellite remote sensing provides large‑scale temperature data, while AI helps spot patterns quickly. Putting these tools together lets authorities issue warnings before severe impacts hit fisheries.
