Abstract

The occurrence of polypropylene and polyethylene bags in the coral reefs of the Mandapam group of Islands has become a concern. These plastic bags pose a potential threat to corals, reef-associated animals, and divers. Field surveys were conducted to track the source of origin of these plastics along the islands and mainland beaches. This study indicated that these plastics are carried by the fishers from the mainland and deployed in the reefs around the islands to catch squids. Finding alternative substitutes to replace plastic bags is an important concern without impacting the livelihoods of fishers. Additionally, awareness among fishers regarding the impact of plastics on marine life needs to be generated and encourage their participation in conservation programs.
