Fishermen in Rameswaram, Tamil Nadu said they would picket Katchatheevu in protest on April 25 at Sri Lanka's impounding of their fishing boats, the Times of India reported.
Demanding the release of their boats, the fishermen association's head, N J Bose said, "foreign secretary S Jaishankar, who will be visiting Sri Lanka on April 7, should take up this issue with Sri Lankan authorities to secure the release of Indian fishing boats".
Earlier this week the Sri Lankan government released 18 of the 38 fishermen currently detained.
