Overall eight species contributed 90 per cent of • The term ‘a miniature ocean’ was coined to describe the Mediterranean Sea (Béthoux et al. 1999) and this Aquaculture has been extended to compare the production: Mediterranean to a giant mesocosm of the world’s oceans (Lejeusne et al. 2010). the European seabass, The Mediterranean basin is an area where different environmental, gilthead seabream, geomorphological, hydrogeological and climate regions meet and allow different trout, aquaculture systems and technologies to develop and succeed. common carp, tilapia, mussels, oysters and Manila clams. Mediterranean Basin • Aquaculture production of marine finfish was dominated by two main species, the European seabass (Dicentrarchus labrax) with 161 058 mt, and gilthead seabream (Sparus aurata) representing with 134 712 mt, in some countries also cultivated in brackish water. • In fact, until 1985, the production of the two main marine species was carried out mainly in land-based systems, such as ponds, and production from floating cages was limited to only 27 mt produced at artisanal level in inshore conditions. • In the early 1990s, the culture in floating cages increased progressively and many farms moved towards the open sea. In 2010 marine aquaculture in floating cages of finfish represented 82.33 per cent of the total production of these two. Marine Aquaculture Production Analyses and Technologies • Spain • Greece • Turkey • Albania Spain • In 2016, a total of 5.105 aquaculture establishments were in operation and producing in Spain. • Of these, 4.782 were marine molluscs aquaculture farms, • 200 were freshwater fish aquaculture farms, • 82 farms were on the coast, beaches, intertidal zones and estuaries, • and 41 were off shore sea cage farms. Spain •The harvest of aquaculture seabass in Spain in 2017 was 21.269 tonnes. •The Region of Murcia has led the production with 6.990 tonnes, followed by Canarias (5.900 tonnes), Comunidad Valenciana 5 (4.972 tonnes) Andalucía (3.261 tonnes) and Cataluña (146 tonnes). 3 1 2 4 Greece • Greece has more than 300 marine aquaculture farms, mostly near the Dodecanese Islands, Ionian Islands and Euboea. • In 2015, the industry raised at least 121,000 tons of sea bream, European bass and mussels. • Marine fish farming holds a dominant position representing 98% of the volume & value of farmed fish in Greece. • Greece ranks 2nd in terms of volume and value among the EU-28 in fish farming (following the UK) Greece Spatial distribution & employment in Marine Fish Farming • Greece 2017 63% of EU supply, 29% of global supply Greece Marine Organic fish farming • Organic production stands for 0,7% of total bass and bream production due to limited market • The initial legislative framework for organic aquaculture in the European Union (EU) was the Directive (EEC) 2092, which was recently replaced by the Directives (EC) 83407 and (EC) 88908 (European Union 1991, 2007, 2008). • At the same time ‘FAO guidelines for the production, processing, labelling and marketing of organically produced foods’ (FAO 2002) and the guidelines in Codex Alimentarius (FAO ⁄WHO 2001) were formulated, as well as general principles for organic production and processing by IFOAM (IFOAM 2007). • Subsequently, governmental bodies and private companies at a national level were formed and produced organic standards for various species in aquaculture (Bergleiter 2001; Brister & Kapuscinski 2001) Greece Marine Organic fish farming • Annual production for 2008 was estimated to be approximately 800–1000 tonnes of sea bass and sea This is because of the extended growing period of 20–24 months compared with 16–18 months for nonorganic fish, and bream (Miliou 2008; Skoufou 2008) (less than 1% of the increased water volumes required for the same level of the total Greek aquaculture production), with mean production, the increased cost of specialized fish feeds and the cost of certification. ex-farm prices at €8–10.5 per kg.

Turkey • Aquaculture is the fastest growing sector in Turkey by showing a growing volume by over 293% in the past decade. • Problems had been mainly occurred between sea farms and other coastal sectors such as tourism, environmental protection, maritime, recreation etc. in Aegean and Mediterranean coasts which were already established most of seabass and seabream farms. • The first marine aquaculture zones were determined in 1988 and were provided moving of sea farms from the in shore and coastal zones. Turkey • Offshore aquaculture is booming in Turkey Aquaculture is the fastest-growing sector in Turkey, which is now the largest fish-producing country in the Mediterranean Basin and the second-largest fish producer in Europe after Norway. In 2017, Turkey featured 425 marine farms, a large majority of which were located offshore. Of these, most farms are dedicated to sea bass and sea bream (total offshore production in 2016 = 150,000 tons). More than half of marine offshore farms in Turkey are located in Muglia in the Aegean Sea. • Turkey’s offshore sectors can certainly be considered a success story in terms of growth, profitability, and market share; every year, over 50 new facilities are installed and the often vertically integrated producers are celebrating record exports to more than 60 countries globally. An “offshore aquaculture” operation in Turkey is defined as one in waters of >40 meters, which can be found within the first nautical mile from shore.

    Master’s Thesis - master Innovation Science Aquaponics Development in the Netherlands The Role of the Emerging Aquaponics Technology and the Transition towards Sustainable Agriculture Mascha Wiegand 6307345 Tulpenweg 17 63579 Freigericht Germany [email protected] +49 1607561911 Supervisor: Prof. Dr. Ellen H.M. Moors Copernicus Institute of Sustainable Development [email protected] +31 30 253 7812 Second Reader: Dr. Koen Beumer Summary A sustainability transition in the agri-food regime is urgently required to interrupt the strong reciprocal effect between current food production standards and climate change (Willett et al., 2019). One sustainable innovation in the agri-food sector is aquaponics. Aquaponics is the combination of hydroponics and recirculating aquaculture in one controlled environment (Somerville, Cohen, Pantanella, Stankus & Lovatelli, 2014). At first sight, the water and nutrient-saving character of aquaponics, amongst other features (Somerville et al., 2014), sound promising for a transition towards sustainable agriculture. Therefore, the following research question emerged: How can the emerging aquaponics technology contribute to the sustainability transition in the Dutch agri- food sector based on Dutch aquaponics developments in the period 2008-2018? To answer this overarching research question, three sub-questions were developed. An integrated framework combining the multilevel perspective (MLP) and the technological innovation system (TIS) was used to understand the dynamics between overall structural trends, the current Dutch agri-food sector and the emerging aquaponics innovation. The innovation was also set into a broader European context. The research was of exploratory nature and used a qualitative content analysis to process 23 interviews, scientific articles, practitioner websites, publication, patent and Google Trend statistics, etc.

Scientific review, however, does not constitute an endorsement of the Seafood Watch® program or its recommendations on the part of the reviewing scientists. Seafood Watch® is solely responsible for the conclusions reached in this report. 2 About Seafood Watch® The Monterey Bay Aquarium Seafood Watch® program evaluates the ecological sustainability of wild-caught and farmed seafood commonly found in the North American marketplace. Seafood Watch defines sustainable seafood as originating from sources, whether wild-caught or farmed, which can maintain or increase production in the long-term without jeopardizing the structure or function of affected ecosystems. The program’s mission is to engage and empower consumers and businesses to purchase environmentally responsible seafood fished or farmed in ways that minimize their impact on the environment or are in a credible improvement project with the same goal. Each sustainability recommendation is supported by a seafood report. Each report synthesizes and analyzes the most current ecological, fisheries and ecosystem science on a species, then evaluates this information against the program’s sustainability criteria to arrive at a recommendation of “Best Choice,” “Good Alternative,” or “Avoid.” In producing the seafood reports, Seafood Watch utilizes research published in academic, peer-reviewed journals whenever possible. Other sources of information include government technical publications, fishery management plans and supporting documents, and other scientific reviews of ecological sustainability.

The development of Hungarian integrated aquaculture is aligned with global trends. In the previous millennium, the utilization of the nutrients introduced into the system was the main aspect of the integration. In Hungary, technologies that integrated fish production with growing crops and animal husbandry appeared, including for example: large-scale fish-cum-rice production; fish-cum-duck production; and integrated pig-fish farming which were introduced in the second half of the 20th century.
