Abstract

The present study was designed to investigate the parasitic monogeneans affecting Argyrosomus regius,Dicentrarchus labrax and Epinephelus aeneus that collected seasonally from different areas of Mediterranean sea region (Port Said province). The monogenean parasites were identified as Diplectanium sp. and recovered from the gills of Argyrosomus regius, Diplectanium sp. in Dicentrarchus labrax and Benedenia epinepheli and Pseudorhabdosynochus epinepheli  were isolated from Epinephelus aeneus. The total prevalence of monogenean infestations among the examined fishes was 45%.  It was 66, 36 and 33% in Argyrosomus regius, Epinephelus aeneus and Dicentrarchus labrax respectively. The spring displayed the highest seasonal prevalence of monogenetic trematode infestations among the examined fishes as 58.67%. Molecular and histopathological studies were investigated.
