Introduction of infected shrimp seedlings and deteriorating environment should be blamed for the recent outbreak of virus diseases in prawn farms, say fisheries experts.
Death of shrimps and crabs has been reported from aquatic farms in the outskirts of the city. The infection, which has caused heavy losses to farmers, has mostly been reported from Vypeen, Kuzhipally, Edavanakad, Ezhikara, and Nayarambalam areas.
Death of farmed aquatic animals including shrimps due to White Spot Syndrome Virus has become a regular feature in the area.
It was in 1996 that the disease was first reported in the district, said B. Madhusoodana Kurup, Vice-Chancellor of the Kerala University of Fisheries and Ocean Studies. Since then, the disease has surfaced at intervals, said Dr. Kurup.
