The Hellenic Centre for Marine Research (HCMR) was established in 2003 by the presidential decree 164/2003 by merging the Institute of Marine Biology of Crete (IMBC), with the National Center for Marine Research (NCMR). The Institute of Marine Biology, Biotechnology and Aquaculture (IMBBC) is one of the three institutes of HCMR. It is based on the premises of HCMR in Crete (Thalassokosmos) and in Attica (Agios Kosmas, Hellinikon, Athens). The institute was created by the merging of the Institute for Aquaculture (IA) with Institute for Marine Biology and Genetics (IMBG) in 2012. The Laboratory of Fish Nutrition and Pathology is located at Agios Kosmas (Hellinikon, Athens). The objective of the Department of Aquaculture is to research the interaction between aquaculture and the environment, to control and reinforce the physical productivity of the marine systems, as well as, to develop methodologies for best aquaculture management. Its Basic Research focuses on the definition, the understanding and the control of the biological mechanisms involved in the rearing process of marine organisms either already reared or with rearing potential (i.e. physiology, pathology, ethnology, developmental biology, immunology, metabolism, toxicology etc). Its Applied Research is focus on the transformation of the accumulated knowledge to applicable technologies which is essential for the private sector. This research direction is implicated in projects related with the Technological Bases of the aquaculture.

Efthimia Cotou will lead WP2: Role of species interactions in IMTA performances. She will be also responsible for the work within WP2 Task 2.1. Seabass, bivalves, and cucumbers in concrete tanks at the coast with an open flow seawater system and contribute with information to WP3 and WP4. Task 2.1. involves co-cultivation of finfish, shellfish and sea cucumbers in four separated outdoor tanks concrete and placed at the coast with an open flow sea water system which pumps the water directly from the sea. Genra of particular interest with high commercial value and high potential for development in IMTA systems in marine waters will be used. In two of the tanks concrete, European sea bass (Dicentrarchus labrax), shellfish (Mytilus galloprovinciallis and/or Ostrea edulis) and sea cucumbers (Holothuria sp.) will be grown. In the other two tanks only fish will be grown that will be considered as control systems. Two different feeds (iso-nitrogenous and iso-lipidic) will be offered to sea bass reared in the tanks. The one feed will contain conventional ingredients (mainly based of fish ingretients) and the other feed will contain novel ingredients (plant). Both feeds seem to influence aquaculture sustainability and contribute to environmental impact. Shellfish, as suspension feeders, and sea cucumbers, as deposit feeders, will be connected to nutrient (C, P, N), particulate organic matter (POM) and energy transfer through water and sediment. Growth performance and survival of all organisms will be evaluated. Toxicity of feeds, water and sediment as well as fatty acid analysis of feeds and sediments that can be used as environmental quality markers will be estimated. As organic enrichment can produce community structure changes in sediment bacterial communities screening of such changes will be also performed in conjunction with the monitor of parasites appearance in fish. The objectives are to elucidate the association between the different species comprise the system (e.g. finfish, suspension feeders and deposit feeders having high commercial value) and the different feeds in order to optimize the culture system and manage its by-products which are related with any reduction of waste production that impacts the environment and to increase feed efficiency that lower the production cost and achieving economic viability through diversification of different trophic level.
