Sažetak
European seabass (Dicentrarchus labrax) and gilthead seabream (Sparus aurata) are prevailing species in Mediterranean marine finfish aquaculture, and despite an increasing demand of the global markets for high-quality seafood, production and technical performance of these two species in the EU has stagnated over the last few years. Two EU Horizon 2020 projects, MedAID and PerformFISH were launched in 2017 to increase the competitiveness and sustainability of the Mediterranean marine fish aquaculture sector. Since the impact of diseases has been one of the factors attributed to the stagnation, both projects envisaged that the concept of healthy fish was a prerequisite for sustainable and profitable aquaculture. A key element of disease surveillance and health management is the availability of fast, reliable, efficient and validated diagnostic techniques capable of detecting the presence of pathogens and timely diagnosis of diseases in fish stocks. Collaborative activities between both consortia launched specific activities to identify all actors involved in diagnostics and to evaluate their diagnostic capacities. An online “Question- naire on diagnostic capacities in the Mediterranean basin” was carried out. The results obtained showed disproportionate diagnostic capacity between European and non- European Mediterranean countries. European countries in general showed a high level of diagnostic capacity with many advanced or spe- cialised labs dealing with the main diseases of concern for sea bass and sea bream. There was evidence of lower diagnostic capacities in non-European Mediterranean countries in contrast with their high degree of production, which poses a significant regional risk considering the important movement of juveniles in the region. These findings indicate the necessity to address the health management in the region in a more holistic, cooperative and harmonised way. An important finding was a lack of capacity to diagnose viral diseases although VNN has been identified to be the main health threat. Efforts should be engaged in capacity building in the countries missing particular techniques and improvement and training is a priorty. For this purpose, national focal points should be established to create an international network aimed at improving and harmonising all future activities in the field of diagnostics of Mediterranean fish diseases.
