Abstract: Surveillance and descriptive studies of mycotic infections were investigated throughout a period of onernyear (2013 to 2014). A total number of one hundred (100) of cultured Gilthead seabream at Marriott Lakernwere surveyed for mycotic infections, whereas clinical and PM lesions were defined. Morphological andrncultural characters of the isolated fungi and yeast were identified from fish tissues and organs. Moreover,rntheir prevalence, incidence and relationship with physico-chemical properties and heavy metals contentrnin water and tissues were evaluated. Infected fish ave orned vertebral column, congested kidney withrnpale liver, fungal patches on the GIT and mottled appearance of the liver with severely congested heart.rnResults were confirmed with histopathological examination, which revealed the presence of fungalrnhyphae and spores in different organs. It was found that about eighty percentage (80%) of the examinedrnfish were infected and total spergillus species were predominant in prevalence of mycotic isolatesrn(32.12%) followed by Cladosporium (20.86%) and Fusarium species (14.45%). Moreover, the incidencernof the mycotic isolates was higher in liver and kidney of the infected fish. The results of water qualityrnparameters indicate that levels of nitrite, ammonia, organic matter as well as cadmium (Cd), lead (Pb)rnand copper (Cu) were higher than the permissible limits. We can conclude that the higher mycoticrninfections of cultured seabream were parallel together with unsuitable water quality and higher heavyrnmetal levels.
