Rameswaram (PTI): More than 20,000 fishermen working for mechanised fishing boat owners at Pamban near here began an indefenite strike today, demanding reasonable prices for their prawn catch.

Fishermen said that the cost of prawn had come down from Rs 800 a kg to Rs 200 a kg. "If we do not get a reasonable price, the profession will become unremunerative," they said.

The government should procure prawns for a reasonable rate, they said.
