Abstract:
Anchor worm are copepod which belong to the phylum crustacean, having 43 accurate Anchor species are described in the world of copepods data base. The genus Lerneae (Anchor worm) of the family Lernaeidae is one of the most damaging ectoparasites of fish and is of major economic concern in all phases of the aquaculture industry from production to marketing. The aim of this study is determining the prevalence of anchor worm in infesting live common carp fish and to investigate the effect of anchor worm on hematology and gills histopathology of common carp in farms of district kohat. Fish samples were collected from various fish farms of district Kohat in which 26 are infested out of 109 fishes and prevalence was recorded. Anchor worm was found more significantin smaller fish in the month of April and May as well as in summer season the anchor worm were found more in number in district Kohat. The rate of infestation was high in zameer Gull Dam as compare to other study area. For hematological and gills histopathology, fish were divided into two groups in which one was non-infected and other was infected group. Fish from each non-infected and infected group were examined for hematological and Histopethalogical study. The hematological analysis showed significant decrease in RBCs, Hemoglobin value,PCV value in infected fish spp as compared to noninfected fish spp while WBCs and ESR value showed significant increase in infected fish spp as compared to non-infected fish spp. The Histopethalogical analysis of infected fish showed severe gills damage including epithelial hyperplasia, displacement and erosion of lamellae, congestion, or hemorrhage in the gill filament. More severely affected gill tissue showed gill sloughing and epithelial lifting and secondary lamellar fusion. The study suggest that Anchor worm should to be observed on routinebasis particularly in summer season. The current study also indicated that exposure to anchor worm spp lead to various damaging effect in C. Carpio as well as indicated the need for proper control measurementsagainst anchor worm. The current research work findings might be fruitful in planning and altering of the management and control techniques for learnosis
