1 Inovative Vertical Mussel Reef Farming an oppurtunity for the recuperation of European seas and economies

2 Sustainability is a vital necessity for all species and human society and economics. It could be achieved only after we have recovered seabed biocenosis damaged by eutrophication.

4 European Sea Dead Zones:

5 World Dead Sea Zones

6 Why the mussels are the solution of the worlds coastal middle zones?

7 Mussels a powerful natural biofiltrator in the marine ecosystem l / m2 per day

8 Restores Light Transmission of the aquatic environment

9 Traditional high quality food resource They mineralize excessive CO2 in their shells and reduce acidification They mineralize and displace the heavy metals from the water

10 Biological benefits: high fertility; self-distribution; self-attachment requiring no additional costs increase the surface for the many epizoic creatures takes a part of zooplankton during a larva faze Participate in the menu of many fishes and other marine and landscape predators

11 What are the anthropogenic impacts on the mussel population: 1. Decreased dissolved Oxygen in the bottom layers as a consequence of the Euthrophycation 2. Introduced of new invasive bottom Predators 3. Bottom Trawling distraction 4. Migration of sediments from the land caused by erosion 5. Covering with mud off bottom bioconozes caused by powerful eutrofication

12 The central question: Gets out the mussel population out of the dangerous bottom layers Forms protected marine Oases/ zones against unsustainable fishery practices How Vertical Mussel Reef Farming overcomes the limitations of the restoration of the mussel population?

13 Technological advantages: The innovative technology expands mussel farming at open sea aquatories of the shelf Do not conflict the navigation because required surface layer remains free for shipping Storm resistant technology Allows a high degree of mechanization in the harvesting process 100% recyclicable materials

14 Ecological benefits (1): Recover bottom communities - gives them access to more favorable upper layers. Restoring marine food chain, the mussels consume phytoplankton, and intensify its relationship with organisms higher in the food chain. Provide habitats and breeding sites diverse in temperature, salinity, pressure and luminosity. Filtrate a wider range of water layers unlike most existing artificial reefs and mussel farms.

15 Ecological benefits (2): It covers a minimal area of seabed and does not deviate the demersal currents Restore light transmission of the aquatic environment, thus restoring macro-algae and their communities Provide shelter from creeping predators (i.e. snails as Rapana venosa, m. Stars, etc.) to numerous benthic and pelagic species Enrich the zooplankton with larvae six-fold the mass of adult reef inhabitants

16 Socio- ecological opportunities (1): New opportunities for aquaculture development in close and open waters, boosting directly and indirectly the Blue Growth Recovery of fisheries and employment - forms natural zones for restoration of fish populations: by counteracting overfishing, bottom trawling and other unsustainable methods and by providing niches and security for breeding, growth and feeding Increased Food Security - with extensive animal protein production in the marine environment in the time of various whether instability

17 Socio- ecological opportunities (2): Counteracts climate change by mineralizing CO2 in the carbonate shells, also reduces acidification of marine water, which protects other carbonate shell species, more sensitive to acidification - i.e. corals, crabs, microplankton, etc. Reduce seawater acidification protecting vulnerable crustaceans and carbonate shell species. Positive effect on coastal and marine tourism by improving coastal water clarity and sealife.

18 That s how resolving such an enormous ecological problem can be seen as an unlimited resource for sustainable blue growth.
