Deliverable D6.2 – Market dynamics

MedAID task 6.2 focuses on the analysis of market equilibrium by the estimation of the supply and demand functions at various levels of the value chain and under different competitive environments.  The market for seabass and seabream is periodically shocked by instability and price volatility, seriously compromising the profitability of the business and the survival of the industry (STECF, 2014, 2016, 2018). The analysis performed here attempts to identify the causes of this instability and to be used as reference for the development of strategic marketing recommendations to avoid upcoming risks and failures.

The analysis is performed at different levels which involve long and short term, international and national markets and disaggregated by value chain levels. Every model was tested for those National markets where information is available, with the required periodicity and in long enough series to fit with the minimum sample size. Unfortunately these data are not available or complete for all countries in the required format. However, the main national markets, covering about three quarters of total seabass and seabream consumption and production, are included in the analysis in one or several models.Continue reading

Seminar on Common pathological problems in marine fish farms and hatcheries as well as the role of biosecurity in preventing their spread

Last month, on 12 June 2019, more than 50 experts attended the MedAID seminar on “Common pathological problems in marine fish farms and hatcheries as well as the role of biosecurity in preventing their spread”, which was held in Alexandria, Egypt, at the National Institute of Oceanography and Fisheries (NIOF). During the seminar, experts from NIOF, the University of Alexandria, the University of Cairo, and CIHEAM Zaragoza presented the project MedAID and the topic “Diseases and biosecurity, the most prevalent diseases affecting marine fish farming in Egypt and in Spain”, as well as the preliminary results of the survey conducted in Spain on Biosecurity measures and management in marine fish farming. The participants discussed the impacts of disease in marine fish farms and possible control measures, including the levels of biosecurity that could be implemented.Continue reading

Local workshop on “Disease prevalence and biosecurity in Spanish marine fish farming”

Last week, on March 28, 2019, took placed in Zaragoza a MedAID Seminar of the Spanish Working Group of the Work-package 4 on Health management, diseases and animal welfare. Forty experts from all the steps of the aquaculture value chain working on fish diseases diagnosis, management and prevention met to analyze the current situation the regarding prevalence of main diseases, about biosecurity measures and the need for a further communication and coordination among involved experts, companies and institutions.

Economic performance indicators for aquaculture

This brief text aims to highlight some of the most common economic indicators used to assess the economic performance of aquaculture production, both from the point of view of the industry as a whole, and from the point of view of aquaculture companies*.
In economics, there is no consensus on which indicator would best determine the economic performance of a sector or company. Indeed, there are used several indicators depending on what is the focus of interest (e.g. the society or the companies) and data availability. Different indicators are usually used or combined depending on the object of analysis. The same profitability indicator used to analyse the economic performance of the investments made, is not suitable to study the economic performance for the owners of the company.
In order to show the main indicators in a simple and clear way, we have divided the text into three sections. Firstly, we describe some of the main indicators used to analyse the economic situation at industry level. Next, we highlight the importance of the relative indicators as a tool to develop comparisons between different countries, production systems or types of companies. Finally, although all the indicators mentioned in the two first sections are also used in the economic analyses at company level, we dedicate the third section to explain other relative indicators that are very important when analysing the economic performance of aquaculture companies.Continue reading

European and Mediterranean Aquaculture data collection and reporting under the STECF

Fisheries and aquaculture are managed under the EU’s Common Fisheries Policy (CFP)
Managing the exploitation of fish and shellfish stocks in European marine waters falls under the European Union (EU)’s Common Fisheries Policy (CFP), which was formally established in 1983 (Council of the European Communities, 1983), and has since undergone reforms in 1992, 2002, and 2013 (EU, 2013). The scope of the CFP extends to joint conservation, management and exploitation of living aquatic resources by EU member states, with the objective of biological, economic and social sustainability.

The CFP requires considering scientific advice (based on Dörner et al., 2018)
The Directorate-General for Maritime Affairs and Fisheries (DG MARE – ( is the European Commission’s department responsible for implementation of the CFP. The CFP explicitly requires the European Commission to take ‘into account available scientific, technical and economic advice’ (EU, 2013) when drafting legislative proposals for the European Parliament and Council. Accordingly, European Commission proposals relating to fisheries management must be based on scientific advice. Hence implementation of the CFP requires both the assistance of specialised experts and the availability of high-quality data and analyses. The European Commission’s own expert scientific independent advisory body on fisheries and aquaculture is the Scientific, Technical and Economic Committee for Fisheries (STECF – The STECF is being consulted at regular intervals on matters pertaining to the conservation and management of living aquatic resources, including biological, economic, environmental, social and technical considerations (European Commission, 2016). The European Commission’s Joint Research Centre (JRC) also has a role in the scientific advisory process by providing advice directly to DG MARE, through participation in the STECF and its Expert Working Groups (EWGs).Continue reading

Health forum discussion on Tenacibaculum

Dates: 11-22 February 2019
Forum coordinator: Dr. Snježana Zrnčić, HVI. Zagreb, Croatia.
Discussion moderators:
Dr. Alain le Breton, VETEAU, France
Dr. Jean-François Bernardet, INRA, Centre de Recherches Virologie et Immunologie Moleculaire, France

After a pause, with proposed discussion on tenacibaculosis, the MedAID Health Forum will again put efforts to gather field diagnosticians, laboratories, relevant authorities in charge of disease management in the Mediterranean mariculture and other stakeholders.

Tenacibaculum infection (previously known as flexibacteriosis) represents one of the first bacterial conditions being reported in marine aquaculture in a large range of species including flat fish like sole (Solea solea) and turbot (Schopthalmus maximus); and finfish, namely sea bass (Dicentrarchus labrax) and sea bream (Sparus aurata). The disease is associated to the infection with bacteria from the genus Tenacibaculum spp. In some marine areas or in recirculation systems, the infection severely threatens production with mortalities rising over 30%.Continue reading

Tenacibaculosis in marine fish

Tenacibaculum infection (previously named flexibacteriosis) represents one of the first bacterial conditions being reported in marine aquaculture in a large range of species including flat fish such as sole and turbot; and finfish, namely sea bass and sea bream (McVicar and White, 1979;Masumura& Wakabayashi, 1977;Bernardet, 1989;Toranzo et al., 2005). More recently, at the 2018 Annual Workshop of the National Reference Laboratories for Fish Diseases (Anonymous, 2018) or from the Assessment of the disease situation made by MedAID (Cidad et at., 2018) tenacibaculosis was considered, together with vibriosis, one of the most important disease for European seabass. In some marine areas or in recirculation systems, they severely threaten production with mortalities rising over 30%.Continue reading

1st MedAID Regional Workshop: Holistic sustainability assessment of Mediterranean aquaculture

MedAID organizes the 1st MedAID Regional Workshop on Holistic Sustainability Assessment of Mediterranean Aquaculture. The workshop will be held at the IRTA Centre Sant Carles de la Ràpita on 24 January.

The objectives of this MedAID regional workshop are i) to present the analysis of the survey conducted to assess the sustainability of the Mediterranean marine fish farming sector (Deliverable D1.2 – Assessment of Mediterranean Aquaculture Sustainability); and ii) to discuss the results obtained with representatives of the surveyed companies, other aquaculture producers and other key players of the sector in order to obtain their inputs and gain a broader vision from the whole value chain of Mediterranean aquaculture.

The workshop will have 70 participants from 14 countries that are involved in the whole value chain – company managers, associations, researchers, aquaculture farm workers, etc.

All updated information on the workshop is available on the MedAID web page and twitter account.

Deliverable D1.2 – Assessment of Mediterranean Aquaculture Sustainability

Aquaculture is a source of food, critical and essential to feed humanity and to ensure the world’s food security, and, also is a business that generates economic interest. This is clearly specified in the FAO’s 2016 State of Fisheries and Aquaculture report, which states that “aquaculture will become the main driver of change in the fisheries and aquaculture sector“. Aquaculture is the main productive industrial activity that will play a crucial role in providing solutions to the millennium challenges. Overall, this is the main idea that exists under the MedAID EU Horizon 2020 project.

Production and productivity of Mediterranean marine fish aquaculture, mainly seabass and seabream, are stagnating or growing slowly as a result of multiple and interrelated causes. To accomplish the objective of improving its competitiveness and sustainability, MedAID is structured in a series of interdisciplinary Work-packages (WPs) to assess technical, environmental, market, socioeconomic and governance weaknesses.Continue reading
