Abstract

This study was carried out to detect the trematodes affecting some marine fishes. Fish species collected were 100 Dicentrarchus labrax and 100 Dicentrarchus punctatus from private farms at Ismailia provinces. There were no pathognomonic signs in infested fishes except marbling of gills in fishes with gill monogenean infestations. Other signs and P. M. lesions were haemorrhages, abrasions on skin, sluggish movement, abdominal distension and emaciation, pale liver, congesion intestine with entritis in some cases. The higher infestation rate was in D. punctatus (52%) followed by D. labrax (35%). The isolated parasites in D. labrax and D. punctatus were monogenetic trematodes (Diplectanum bocqueti) and Digenetic trematodes (Acanthostomum sp.and Allostomachicolina secundus). Detection of Acanthostomum sp. using molecular biology (PCR) was recorded. Seasonal prevalence in relation to fish sex, body weight, body length and infestation, statistical analysis and histopathological picture was also recorded.
