B. Fronte, L. Rossi, C. Sangiacomo, E. Merega and C. Bibbiani: Sustainable diets for farming seabass and seabream in multitrophic aquaculture: the SIMTAP system in Italy
Abstract
Currently, aquaculture is asked to provide food to the growing world population. To accomplish this task, a larger production of commercial feeds is necessary. Both the fishmeal and fish oil shortage, and the overseas and too intensive plant grains production, are the main issues that contribute lowering aquaculture sustainability. Hence, to feed farmed marine fish, ingredients such as microalgae, deposit- and filter-feeder organisms might be sustainably self-produced within the SIMTAP system.
In the present talk, the survival rate, growth performances and morphological parameters of juveniles and adult Gilthead seabream and European seabass, fed alternative and potentially sustainable diets, will be described.
Overall, a production loss of about 7% was observed when the alternative diets were used.
