ಮೇನ್ಸ್
GS3 (Environment): Whale strandings on India's west coast signal pressures on marine mammals such as ship strikes, entanglement in fishing gear and ocean noise. Protection under the Wildlife (Protection) Act, 1972 and the species' Endangered IUCN status frame the policy response. The way forward lies in systematic stranding records, a trained rapid-response network, ship-lane management and fisheries bycatch mitigation.
