Thirteen fishermen were detained along with three boats from Jagadapattinam in Thanjavur district while another 14 fishermen were held from Rameswaram with thier three boats when they were fishing in the mid-sea late Wednesday night.
The Lankan navy personnel also damaged their fishing nets, Assistant Director of Fisheries Department Sekar said.
The fishermen, who were taken to Kankesanthurai naval base, were released on Thursday morning after a warning not to fish in the Sri Lankan waters, Sekhar said.
Fishermen from Nagapattinam, Tiruvarur, Karaikal, Thanjavur and Pudukottai had decided to boycott fishing indefinitely from Thursday in protest against the incident.

Meanwhile, NDA ally PMK on Wednesday said Sri Lanka was treating India 'badly' on the issue of arrest of Indian fishermen and called for strong steps to rein in Colombo.

Party founder S Ramadoss said the latest incident of arrest had happened on Tuesday, on a day when Lankan President Mahinda Rajapaksa was in India for a personal visit even as Parliament was discussing the fishermen issue with the government responding to it.

"These are examples of how badly Sri Lanka treats India on the fishermen issue," he said in a statement.

Rajapaksa government "should be taught a lesson" it can never forget in this matter, he said but took a dig at Prime Minister Narendra Modi for wishing a third Presidential term for the Lankan leader.

He also faulted the state government in its approach in the matter, saying both Chief Minister O Panneerselvam and his predecessor Jayalalithaa confined themselves to just writing letters and urged the former to personally take up the matter with Central government if it failed to warn Sri Lanka.

He said India should adopt 'shock treatment" tactics followed by former Prime Minister Indira Gandhi and former Chief Minister of the state, M G Ramachandran, but did not elaborate.
