"The historic rights of our fishermen to fish in the traditional waters of Palk Bay are being continuously denied and the root cause of the problem is the unconstitutional ceding of Katchatheevu to Sri Lanka under the Indo-Sri Lankan agreements of 1974 and 1976," she said in a letter to Prime Minister Narendra Modi.
She urged the Centre to take steps to secure the release of 80 fishermen arrested by the Lankan Navy, including 23 fishermen arrested on July 4 and 5, besides 101 boats seized by them.
"I reiterate that only the retrieval of Katchatheevu will ensure the restoration of the peaceful pursuit of their traditional livelihood by our fishermen in the Palk Bay," Jayalalithaa said.
Urging the Centre to impress upon the Sri Lankan government to release the fishing boats that were already in custody, she requested Modi to direct the External Affairs Ministry to initiate earnest efforts in finding a "permanent" and "pragmatic" solution to the livelihood issue of fishermen.
On July 3, Jayalalithaa had written to Modi, urging him to take steps to secure the release of five fishermen arrested by the Lankan navy on the same day on charges of fishing in its territorial waters.
