Fisheries Minister Mahinda Amaraweera said in a statement yesterday that the Indian government has been informed about this decision.
"They should never return to violate our International Maritime Boundary Line (IMBL)," Amaraweera said.
He said that Sri Lanka's earlier decision not to release the boats and equipments while releasing the fishermen had its desirous effect.
The Indian government has now banned bottom trawling. Amaraweera said the views of the local fishery organisations were also sought before making the decision to release the Indian boats.
On Wednesday, Tamil Nadu Chief Minister K Palaniswami sought the intervention of Prime Minister Narendra Modi for getting back 135 fishing boats of state fishermen impounded by Sri Lanka over a period of time, saying the fishers had been deprived of their livelihood.
Of the 135 boats, a total of 61 were apprehended in 2015, 53 in 2016 and 21 in 2017, the Chief Minister noted.
