When contacted, assistant director of fisheries Amin Jan confirmed the prevalence of the disease and said the department had assembled the samples of infected fish from different points in the river from Shoghore to Arandu.

He said the symptoms of the infected fish were lethargy, external hemorrhage at mouth, ventral and near pelvic fins while infected fish tended to rest at banks where the water current was less severe.
