Title : A yearly assessment of pathological condition encountered in Mediterranean fish species in a Greek aquaculture region


The products of Greek aquaculture as a whole constitute in recent years the second most important agricultural product of our country. The intensification of fish farming in our country and the great development of this rapidly growing industry are threatened due to the presence of diseases. These diseases cause significant financial losses due to the high mortality of the fish population but also due to the cost of treatments. Their investigation is therefore considered important and crucial in order to develop effective prophylactive measures, like vaccines.

The prefecture of Thesprotia was chosen for the fish samplings as it represents 10% of the total Greek aquaculture production. The samplings took place for a whole year. The fish species cultured in this area are sea bass, gilthead sea bream, meagre and red porgy. Different bacteria were identified depending on the fish species from which they were isolated and the seasonality of the diseases. Beta Nodaviruses were isolated from sea bass and lemphocystis virus from gilthead sea bream, considering the presence of viral diseases. The most prominent parasites were Sparicotyle chrysophrii, Enteromyxum leei, Lernathropus kroyerii and Caligus minimus. All four fish species from which the samples were collected from, developed bacterial diseases yet for two of them, there is no commercial vaccine available.

The results of this study shed some light considering the pathological conditions that occur in the farms of Thesprotia prefecture and are caused by bacteria, parasites and viruses. The main problem that arose is that there are no effective prophylactive measures to foster this great industry.

More and extensive research is needed to enlighten the actual prevalence of bacteria in this sector and more advanced molecular methods are needed such as whole genome sequence to study the different strains and chose the common antigenic epitopes from different areas of Greece in order to produce effective vaccines.

What will audience learn from your presentation?

  • The presence of pathogens causing important diseases in the Greek aquaculture industry.
  • This research will expand our knowledge of prophylactic measures in aquatic species, this knowledge is useful for teaching purposes also.
