Present study was undertaken to study the alterations in blood biochemical indices due to the presence of helminth parasites in Schizothorax and carp fishes collected from Dal and Anchar lakes of Kashmir. The prevalence of parasites and other indices were assessed and compared with the alterations in the serum biochemical indices of infected as well as uninfected fishes. During the investigation three helminth parasites viz. Pomphorhyncus, Neoechinorhyncus and Adenoscolex were recovered from the infected fish specimens examined. The overall prevalence of parasites in Schizothorax and carps of Dal Lake was 48.54% and 41.23% respectively, while as in Anchar Lake, it was 53.70% and 50.50% respectively. In Dal Lake, among Schizothorax fishes the highest prevalence was of Pomphorhyncus parasite (26.21%) followed by Neoechinorhyncus (19.42%) and Adenoscolex (15.53%). In case of carp fishes the order was Neoechinorhyncus (21.93%) followed by Pomphorhyncus (19.30%) and Adenoscolex (14.04%). In
