Prevalence ofSympatric Parasites in the Flathead Grey Mullet Mugilcephalus(Linnaeus, 1758) - Arabian Gulf - Saudi Arabia
Journal Title: Haya: The Saudi Journal of Life Sciences - Year 2018, Vol 3, Issue 4
Abstract
Abstract:A total number of 1042 flathead mullet Mugilcephalus were searched for parasites during summer & autumn 2015 and winter & spring 2016. Six different parasite taxa belonging to Microsporidia, Myxozoa, Ciliophora, Anisakidae and Gnathostomatidae were identified. The total number of infested mullets along the study period with one or more parasites was 396 representing a percentage of 38.0%. Mullets were infested with Microsporumvelveticumthrough ingesting the intermediate host. This parasite was observed in the intestinal epithelia, adipose tissue, liver, stomach epithelia, muscles and air bladder. Myxidiumdepressum was observed in the liver and gall bladder of infested mullets in a plasmid stage that had undergone sporogony forming multicellular myxospores. Trichodinamurmanica was observed on the gill surface, the operculum and respiratory epithelium where superficial to deep ulcerative lesions were visible. Third Larval stages of Anisakis simplex, Raphidascarisacus and Gnathostomaspinigerumwere observed free in the duodenum and ileim or encapsulated in the stomach epithelia, liver, and muscles. The infra-community of protists was highest in winter and fall while for parasitic nematodes was during spring and summer. Seasonal fluctuation of the parasite community was demonstrated by using standard calculations. Keywords: Mugilcephalus; Microsporidia; Myxozoa; Ciliophora; Anisakidae; Gnathostomatidae.
