A case study was designed to apply the recommendations obtained in the tasks of the WP2 of MedAID H2020 project in two different sites located along the Mediterranean basin.

Two fish farms in different locationswere selected in West Mediterranean-Spain and East Mediterranean-Greece. A comparison between the results of seabream ongrowing in 2 different sea sites in the Mediterranean sea was carried out during a whole production period (from June 2018 to October 2019) in semi-industrial sea cages (16 m diameter) using the best feeding practices selected from the different research tasks of WP2.

In order to produce comparative data between sites the same batch of fish (provided by Galaxidi Marine Farm in June 2018) and feeds (provided by Dibaq Group when the fish reached 100 g) were used. The fish were fed 2 different feeds in the studied period of low (January-June 2019, 45/16 Protein/Lipid ratio and 22/7 FM/FO) and high (July-October 2019, 45/20 P/L, and 16/7 FM/FO) temperatures with diferent DP/DE and FM/FO ratios, using only one dose per day.

The fish were harvested (420-455 g) and the results in production yield, fillet composition and sensory attributes compared
