Abstract: During the spring of 2019, a marine fish survey from Shalateen port was conducted to detect the prevalent parasites, bacteria, and fungi pathogens in order to fill the gap in data on fish pathogens in this area. Gross examination revealed no lesions except excessive mucus secretion in some samples which were usually associated with monogenean infestations. The overall prevalence of parasitic infection was 18.5%. Bigeye snapper had the highest percentage (71.4%), followed by Arabian monocle bream (33.3%) and Yellowstripe goatfish (39.3 %). The presence of Vibrio and Photobacterium species is indicated by the use of selective medium for bacterial isolation. In terms of fungal infection, Aspergillus was the most prevalent genus, represented by three species:
A. flavus (40 CFU/g),
A. niger (57 CFU/g), and
A. fumigatus (20 CFU/g). Some other genera were recorded as
Cladosporium sp. (25 CFU/g),
Alternaria (13 CFU/g) and
Penicillium sp. (6 CFU/g). All examined fish species had a high record of yeast species.
