Table 2 Growth parameters (K, FCR, SGR (%)), feed quantity provided and mortality during the experimental period for the two diet groups (conventional vs. low marine protein; n = 3 cages per diet group).

From: Growth performance, gut microbiota composition, health and welfare of European sea bass (Dicentrarchus labrax) fed an environmentally and economically sustainable low marine protein diet in sea cages
