Sources said aqua farmers in the district have been complaining about troupes of shrimps perishing in the viral disease attack over the past one month. Shrimps are farmed along the coastline betwixt Nagore and Kodiyakarai. M Chandirabose, whose shrimp farm spans around five acres in Therkku Poigainallur in Nagapattinam district, said, "Tons of shrimps aged in the age group of one month died due to the viral disease. The loss I incurred amount of over Rs 5 lakh.
I usually harvest around 15 tons of shrimps. But only 200 kilos of shrimps harvested have turned out to be healthy. Others died due to the disease."
