A total of 27 5 specimen of Channa punctatus were obsert ed for infestation of parasite. The study was done on monthly basis for seasonal occurrence of digenean trematodes from June 2014 to May 2015. The prevalence percentage of Diplostomulum cerebralis in Channa punctatus was obsemed to be 1i%. The occurrence of this parasite was found highest during winter season i.e. in month of November and Decemben Findings show that beginning of the breeding period and feeding habitat are influencing the seas onal ity of paras itic infection.
