Studies on the Prevalence of Ecto Parasites of Gulfarm (Cyprinus Carpio) from Carp Fish Hatchry District Badin, Sindh, Pakistan

Abstract

The study has been carried out over period of one year from August 2011 to July 2012 to find out the parasitization of different fish species cultured at carp fish hatchery district Badin with special reference to Gulfam, Cyprinus carpio. 263 specimens of fish were examined for the determination of prevalence of ectoparasites. It was observed that the highest infection rate (66.6%) was observed in C. carpio followed by C. punctatus (50%) and the lowest (11.7 %) was recorded from C. mrigala during the present investigation. The prevalence in fish was the highest in late summer (September-October) and the lowest prevalence was found in the early summer (April-May).
