The Sri Lankan Navy on Monday apprehended four Indian fishermen along with a country boat near Punkudi Island allegedly on charges of illegal fishing. All the detained fishermen, belonging to Tamil Nadu and have been sent to Kankesanthurai Naval camp for further interrogation.

The incident comes days after 12 Rameswaram fishermen with two boats near Delft Island were arrested by Sri Lanka on Friday.

The arrests took place when a routine patrolling party of Fast Attack Craft (FAC) detected movement and found the fishermen found illegally fishing in Sri Lankan territorial waters.

Notably, there has been a sudden rise in the number of Indian fishermen being arrested along the Palk Strait region.

Earlier, after the growing concern over the Indian fishermen being detained, Tamil Nadu government on Friday flagged concerns after Sri Lanka amending its Fisheries and Aquatic Resources Act put a ban on bottom trawling in the Palk Bay.

As per the new rule, a fine of 50,000 Lankan rupees (LKR ) will be imposed along with imprisonment of up to two years on those found guilty of bottom trawling — a dangerous method where the fishermen drag large nets with heavy weights across the seafloor to catch fishes in bulk.

Apparently, the destructively dragging method scoops everything in its path, damaging the sea life form including the corals.

Also, Tamil Nadu Chief Minister Edappadi K Palaniswami has written a letter to Prime Minister Narendra Modi asking the Centre to take necessary steps against the move Sri Lankan move.

He also highlighted the concern over several arrests including 50 fishermen and at least 143 boats in Sri Lankan custody.
