Ichthyobodo spp. Infection in Meagre (Argyrosomus regius) from Turkey: Parasitological and Pathological Findings.

Abstract

OBJECTIVE: The aim of this study is to describe the first report of Ichthyobodo spp. infection in meagre (Argyrosomus regius) fry in a marine aquaculture facility in Turkey. METHODS: The material of the study was composed of 30 meagre A. regius in 2-3 g weight taken from the fry adaptation unit of a fish farm in the Aegean Sea. In this study, parasitological and pathological examinations were performed on the meagre. Ichthyobodo spp. was determined on the body surfaces and gills. RESULTS: Pathological examination revealed grayish mucous and erosions between the pin head and lentin over the skin of the examined specimens. Microscopic examinations revealed significant spongiosis, vacuolar degeneration, and hyperplasia in epidermal malpighian cells and hyperplasia in goblet cells. CONCLUSION: In the present study, Ichthyobodo spp. infection was for the first time determined in an alternative cultured meagre in Turkey.
