THE ROLE OF AQUACULTURE İN THE FUTURE OCEANS Evrim Kurtay, Mustafa Karga, Osman Sabri Kesbiç, Murat Yiğit, James Fox * *, Barbaros Çelikkol* Çanakkale Onsekiz Mart University, Faculty of Fisheries, Çanakkale-Turkey *University of New Hampshire, Mechanical and Ocean Engineering, UNH - USA * * University of Plymouth, School of Marine Science and Engineering, Plymouth – UK Introduction There is increasing pressure on marine fisheries and resources, mainly by uncontrolled or over fishing practices. Due to the increasing need for seafood, a valuable protein source for human consumption, aquaculture has become one of the most important industries for the supply of marine fish production for future generations. The sustainability of aquaculture plays an important role in fulfilling this new duty with success. Aquaculture, the production of aquatic animals and plants for food, will have to face some challanges in the future in terms of the ecological, social and health impacts on the environment. Keywords: sustainable aquaculture, environment, integrated aquaculture, IMTA. Figure 1: Integrated Multi-trophic Aquaculture Aquaculture will need to diverse the production scale into a combination of aquaculture of fed organisms (fish or shrimp) with the culture of organisms which extract either praticulate organic matter (shellfish) or dissolved inorganic nutrients(seaweeds). This type of combination, the so called Integrated Multi-trophic Aquaculture, helps balancing the biological and chemical process at site. IMTA seems to be the hope for a viable future of marine ecosystems and the production of highly valuable protein sources for meeting the demand of the increasing world population as well as eradication of hunger.

Discussion and Results: Aquaculture in oceans will be more significant, as a protein source of human nutrition, by the next century. Developing technologies in aquaculture will play an important role for sustainable production of seafood from oceans.
