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.

Bottlenecks in diagnostics of Mediterranean fish diseases
Zenodo (CERN European Organization for Nuclear Research), 2020
Three independent Horizon 2020 projects are prioritising a common task of solving diagnostic issues using different approaches and strategies. PerformFISH focuses its research objectives on diagnostic methods, MedAID has prepared a diagnostic manual for the most devastating fish diseases of the Mediterranean and ParaFishControl has prepared a diagnostic manual on parasitic diseases of European aquaculture species. Currently, the projects are investing large collaborative efforts to reinforce their tasks and to deliver mutual and cutting-edge material on the subject. Nevertheless, further efforts for the harmonisation, standardisation and validation of diagnostic methods for infectious diseases in Mediterranean aquaculture are needed, involving as many relevant stakeholders and experts as possible. The main goal of the workshop (WS) "Bottlenecks in diagnostics of Mediterranean fish diseases", organised during the 19 th International EAFP conference on Diseases of Fish and Shellfish, was to present results already obtained from the projects and discuss the bottlenecks in diagnostic procedures of target groups of pathogens. The WS provided an ideal environment and opportunity to exchange and discuss experiences and data with international experts in the diagnostic field attending the conference. Interactive discussions on diagnostics for a specific group of pathogens have resulted in highlighting new initiatives needed in the management of diseases in Mediterranean aquaculture. Furthermore, the WS emphasised a need for the establishment of this strong interactive network which will collaborate to receive, collect, compile and analyse all information gathered from different parts of the region.
Deliverable 3.1 - Diagnostic methods for Mediterranean farmed fish
2020
Despite the technological progress applied in recent years to the various production phases of Mediterranean Marine Fish Farming (MMFF), from reproduction to nutrition, several welfare and health issues of farmed fish still represent relevant limiting factors for sustainable production. In particular, the attempts to increase and diversify MMFF productions have been often accompanied by the emergence or reoccurrence of transmissible diseases strongly conditioned by management and environmental factors with consequent significant economic losses and repercussions on fish welfare and health parameters. The experience gained in the attempt to control diseases has amply demonstrated that the treatment (when applicable) is often not conclusive, highlighting that the "disease event" is the result of many interacting factors linked to the pathogen, the host and the environment (intended as production system and surrounding ecosystem), which underly the occurrence of disease and i...
Aquaculture Environment Interactions, 2013
Although aquaculture in the Mediterranean is a relatively young industry, finfish diseases have been reported to cause considerable problems and mortalities among the farmed stocks. In general, the farming activity and the open design of Mediterranean aquaculture systems allow the transmission of infectious pathogens within and among farm facilities. Fish health and biosecurity programmes at farms have focused on the most obvious pathways for transmission of pathogens, i.e. through transport of infected farmed fish from hatcheries, infected equipment, staff and vessels, as well as through water currents. However, little attention has been devoted to the potential risk of pathogen and disease transmission in Mediterranean open-sea aquaculture through movements of fish. The present study focuses on the importance of considering possible pathogen transmission between reared fish, farmed escapees and farm-aggregated fish when making management decisions.
Bulletin of The European Association of Fish Pathologists, 2022
Aquaculture of European sea bass (Dicentrarchus labrax) and gilthead sea bream (Sparus aurata) is an essential activity in the Mediterranean basin. Several EU Horizon 2020 and regional projects are focusing on the improvement of their farming performance. This workshop aimed at displaying, sharing and discussing projects' achievements among interested colleagues engaged to work with fish diseases. The most innovative research outputs aiming to improve the European mariculture were presented during this workshop, including updates from EU Horizon 2020 projects MedAID, PerformFISH, ParaFishControl, FutureEUAqua and the Italy-Croatia Interreg project AdriAquaNet.
Fish health in Mediterranean Aquaculture, past mistakes and future challenges
Bulletin of The European Association of Fish Pathologists, 2016
A significant production in European aquaculture consists of production of approximately 135.000 tons of European sea bass and 139.000 tons of gilthead sea bream in the Mediterranean basin according to FEAP. Despite the relevance of these species, both in terms of production and economic value, no specific provision is given in the legislation regarding the survey of important diseases. All information available about infectious diseases and priorities to further develop this production are quite fragmented and jeopardized. Since 2012 EURL for Fish Diseases started a survey involving a number of private and institutional experts depicting the most important diseases. Each year the data are compiled and presented at the EURL Annual Workshop. The increasing relevance of the health aspects in the Mediterranean aquaculture seems to require more accurate and comprehensive interpretation involving as much professionals as possible. The initiative of this workshop was build in order to cre...
Ecopathology in aquaculture: risk factors in infectious disease outbreak
Veterinary research, 1995
This paper describes a study of the risk factors associated with disease outbreaks in fish species of fish farms and rivers of north-east Spain. We focused our work on the isolation of fish pathogens (bacteria, virus), the water quality (physicochemical and microbiological quality) and management characteristics. We have observed 2 important viral diseases, infectious pancreatic necrosis and spring viraemia of carp, and 2 important bacterial ones, furunculosis (Aeromonas salmonicida) and bacterial kidney disease (BKD) (Renibacterium salmoninarum). Our preliminary results show that there are some potential risk factors associated with the main diseases of fish, such as fish age, fish species, production system, season and water temperature, but their role depends on the disease.
