Abstract

An outbreak of ectoparasite infestation affected carp fish reared in ponds (10x 6x 3 m) be versity  during the period from June to late September. Parasitological examination revealed high incidence of ectoparasite infestation among carp fishes reach up to 80 & The crustacean copepode was identified as lernea elegans. Physical and chemical analysis of pond water indicated that, although the mean values of pH, temperature, dissolved oxygen, turbidity, ammonia and nitrite were relatively high, but they did not reach any harmful level on fish in pond. Trials for control of lernea infestation was done through application of strict hygienic measures in pond in association with readjustement of all water quality parameters followed by adding of Metrophonate (0.25 mg/L) of pond water for 7 successive days (first treatment). Then freshly prepared potassium Permenganate was added to water to give final concentration 0.25 mg/L. (second treatment) was succeeded in reducing the infestation rate from 80 % to 10 % which in turn decreased into 5% by adding of Monosex Tilapia (O. niloticus). The obtained results, indicates the importance of regular inspection of Carp fish in ponds for carly detection of ectoparasite infestation besides regular examination of different water parameters to monitor it's availability for fish reaning and removal of anyharmful impurities.
