Abstract species Mugil Tobar) The present work was done on six marine [Sparus auratus cephalus (Bori), and M. chelo (Halili)] obtained from the fish 77 6- (Denees), Morone labrax (karoos), M. saliens (Garana), M. capi to Suez Canal water at Ismailia. The investigation revealed that the total infestation rate reached 28.25% as 100 fishes out of 354 were posi ti ve for enteric helminth parasi tes. Seasonally, the highest incidence ( 45.98 %) was observed during the winter season which was followed by spring (31.43%) and autumn (28.07%), while the lowest incidence was observed during summer (7.23%). The Morone labrax was the s us cep t i.b Le f ish species for enteric helminth parasites infestation (45.46%), followed by Mugil saliens (41.18%), M. cephalus (34.09%). M. capi to, M. chelo and Sparus auratus were represented by lower rates of infestation as 25%, 22.45% and 20.41% were infested respectively. Trematodes were recorded among 17.23% of the examined fishes with their highest peak during winter season. 78 This was followed by cestode worms (5.37%) with the highest record also during winter. Nematode and acanthocephala were nearly equal as they represented by 4.24% and 4.8% with their highest peaks during winter and spring respectively. The study revealed also the collection of 15 helminth parasi te species. Trematode worms were repre- sented by 11 species mainly, Acanthostomum imbutiformis, Basidiodiscus ectorchis, Bucephalus labracis n.sp., Cainocreadium labracis, Cainocreadoides serrani, Hama- creadium rnutabile, Haploporus benedenii, Haplosplanchus cau~atus, Haplosplanchnus pachysornus, Haplosplanchnus stunkardi and Lecithobotrys suezcanali n.sp. Cestodes were represented by only two immature worm species, Nybelinia and froteocephalus species. Nematodes were represented by only one species Cosmoxynemoides species. Also one species from acantho- cephala was obtained, Neoechinorhynchus rutili. The morphological description of all the collected different helminthes was given. |
