The Central Marine Fisheries Research Institute will evolve mitigation strategies for marine fisheries and develop an ecosystem-based fisheries management technique for sustaining fishery resources, according to its director N.G.K. Pillai. Speaking to The Hindu here on Tuesday, he said the mitigation plan would highlight the impact of climate change on fish species and the shift in the distribution of commercially important varieties like oil sardine that had started migrating in large numbers from the Kerala coast to the northern areas in search of cooler water.
