The court in Mannar ordered the fishermen's release, fisheries department officials said quoting information received by them this evening.
They were released on a day when External Affairs Minsiter Salman Khurshid began his two-day visit to Sri Lanka where he raised the issue of Tamil Nadu fishermen.
More than 60 fishermen were released by courts in Sri Lanka in the last ten days while several others are lodged in prisons there.
