Four fishermen, who ventured into the sea for fishing on Wednesday in a trawler, were stranded on the high seas after the engine developed a snag.

Sources in the Fisheries Department said the fishermen — Paralogaraj (17), Wilson (26), Paralogarajan (19) and Jackson (22) — were stranded near Thalaimannar in Sri Lanka and all of them were safe.

The fishermen, hailing from Pamban, were part of more than 2,500 fishermen who set out to the sea in 577 trawlers on Wednesday. All the other fishermen returned on Thursday morning, the sources said.

A rescue team would leave on Friday morning to rescue the fishermen and tow the faulty boat back to the shore, the sources added.

Meanwhile, sources here said the Mannar District Court in the island nation extended the judicial remand of eight Rameswaram fishermen till July 11.

They were arrested by the Lankan navy on June 15 for allegedly fishing in their waters.

When they were produced before the court on Thursday after the expiry of the remand period, Magistrate Anandhi Kanakaraj extended their remand, the sources said.
