Epizootiological survey was performed with emphasis on pathogen agents and their geographic distribution of the most severe bacterial and viral diseases: vibriosis, photobacteriosis, tenacibaculosis, furunculosis and motile aeromonas septicemia, and viral nervous necrosis. Σhe most important cultured Mediterranean finfish species, European sea bass, gilthead sea bream, sharpsnout sea bream, red porgy, white sea bream, were studied. Eleven aquaculture case locations and the causal pathogens maps were designed with Geographical Information System (GIS) ARC-MAP program. These maps included the Greek coast-line and Argolicos, Argosaronicos – Saronicos, Corinthiacos gulf, Miticas Aitoloacarnania coast, Ionian Sea Island coasts, river Louros delta, Central, East and West Amvrakikos gulf, Igoumenitsa and Sagiada coasts, Maliacos gulf, Atalanti Phthiotis coast and North Evoicos gulf, Porto Lagos lagoon rearing locations. The time period of this survey was 1998 – 2014. For European sea bass, 178 outbreaks were recorded for: a) vibriosis (100), caused from Listonella anguillarum (12 – 260C), in most of Greek rearing locations,from Vibrio harveyi (19 – 220C), V. alginolyticus and V. splendidus II (160C), especially in Argolikos gulf, North Evoic gulf and Ionian Island coasts, and from non-specific Vibrio spp. (4), b) photobacteriosis (34) caused from Photobacterium damselae subspecies piscicida (19–250C) in the majority of Greek rearing locations and Photobacterium damselae subspecies damselae (19–24.50C), mainly in the above three locations, c) tenacibaculosis (7) from Tenacibaculum maritimum (220C), in the above three locations, and, at 180C, in Portos Lagos lagoon, d) motile aeromonas septicemia (MAS) from Aeromonas sp. (7), A. sobria (3) at 220C, in three locations, and A. hydrophila (7), 2 outbreaks at 150C, and 1 outbreak at 210C, in Saronicos – Corinthiacos and Saronicos – Argosaronicos gulf, and 4 cases, at 280C, in river Louros delta of West Greece e) viralnervous necrosis (16) from Beta-nodavirus RGNNV genotype, ...
