The circular economy is a concept widely applied to the primary production sectors, that considers every resource is used locally without producing waste. All products are consumed or sold, and their potential waste or sub-products are re-utilized leading to a more sustainable production and valorisation of bio-resources. The aquaponics production system is an example of circular economy. Aquaponics is the combination of aquaculture with hydroponics. It is a sustainable production method where it is possible to produce animal protein and vegetable protein simultaneously in an integrated closed system without waste production and with low water consumption. This production method makes an efficient use of resources, as producing the fish and the plants separately would use more water and land area. It is a very interesting system to use in urban areas where fertile soil is not available and in areas where the water is a limited resource as the islands. At the Calheta Mariculture Centre CMC we have identified the main sub-products originated by farming activities in the island and then follow with the characterization of their major bio-molecules with interest for fish compound feed. We have so far identified as sub-products: grape waste, cabbage and carrot rejected products and trimmings and the Aloe vera. These sub-products will now be analysed, determining their proximal composition and by characterizing them by identification and quantification regarding some important molecules for fishmeal and as the polyphenol compounds, pigments, bio-disponible amino acids and fatty acids. Other of our goals is to set up two aquaponic systems, one of freshwater and another of seawater inside greenhouses, aiming to conduct fish nutrition and vegetable growing essays. The freshwater system will be located at a local organic farm and combine rainbow trout maintenance Oncorhynchus mykiss with lettuce production in a balanced system. The O. In fact, O. In the freshwater system we aim to test the effect of different trout densities and different diets in the development of hydroponic varieties of lettuce. In the seawater aquaponic system, we aim to integrate for the first time grey mullet maintenance tanks with the growth of halophytes plants from the Salicornia and Sarcocornia genus in different salinities. The grey mullets e. In this system we aim to test the effect of the maintenance of grey mullets at different salinities and diets in the development of the halophytes selected.
