This paper describes the first report of gill disease in gilthead sea bream (Sparus aurata L.), cultured in the Northern Adriatic near the island of Cres in Croatia. The pathological findings of cultured gilthead sea bream were examined in detail, using prompt clinical and necropsy examination, bacterial and hematological analysis. Beside yellowish-brown, swollen and clumped gills, there were no other apparent changes in the diseased fish. Bacterial analysis of these fish revealed the presence of mixed infections. The predominant bacterium from affected gills was Stenotrophomonas maltophilia. Furthermore Aeromonas salmonicida masoucida/achromogenes and Empedobacter brevis were also identified. Fish with affected gills had significantly decreased serum proteins, specific weight and haematocrit compared to fish without changes of the gills.

A total of 150 gilthead seabream Sparus aurata L., from North Lake of Tunis, Tunisia, were studied for protozoan and myxozoan parasites. The parasitological survey revealed the presence of ectoparasites (Amyloodinium ocellatum Brown, 1931, Trichodina lepsii Lom, 1962 on the gills) and endoparasites (Ceratomyxa sparusaurati Sitjà-Bobadilla, Palenzuela et Alvarez-Pellitero, 1995 infecting the gallbladder, and Eimeria sparis Sitjà-Bobadilla, Palenzuela et Alvarez-Pellitero, 1996 parasitizing the intestine). This is the first record of Amyloodinium ocellatum, Trichodina lepsii, Ceratomyxa sparusaurati, and Eimeria sparis in S. aurata from Tunisian waters. Data on prevalence and intensity of infection are provided. A comparison of the present species with previously described species in cultured gilthead seabream from other Mediterranean countries is also presented. In this study Trichodina lepsii is identified for the first time in Sparus aurata. A taxonomic description of this species based on silver nitrate method is provided.
