July 13, Colombo: Fishermen in Puttalam District have been able to reap a good harvest of the giant freshwater prawns (Macrobrachium rosenbergii), also known as "Kara Andu Issa" these days.
The National Aquaculture Development Authority (NAQDA) had taken steps to release post larvae giant freshwater prawns to many tanks in the Puttalam district about six months ago. The prawns are now well grown and ready to be harvested.
One kilogram of freshwater giant prawns sells for a price between Rs. 1000 -1300.
Although these prawns live in the sea water, they migrate to brackish water for breeding. The NAQDA plans to release this indigenous prawn species in more reservoirs in order to uplift the living standards of the fishermen.
The National Aquaculture Development Authority says it is also attempting to earn foreign exchange through prawns farming.
