Ahadulla Sajili, Bureau of Fisheries and Aquatic Resources (BFAR) regional director, inspected several fishponds in the village of Vitali, 73 kilometers east of the city, where there were reported infection of "white spot" virus that have caused the death of fishes and prawns.
Sajili said the sudden change of temperature combined by the low water volume contributed to the death of the fishes and prawns aside from the virus.
The City Agriculture Office and BFAR have observed that water volume of the fishpond is not suitable for the livability of the aquatic resources being cultured, Sajili said.
