Inclusion of Isochrysis aff. galbana in organic diets of European sea bass juveniles: effects on growth, feed utilisation and fillet composition

A study was carried out to evaluate growth response, feed utilization and quality traits of the edible portion of sea bass (Dicentrarchus labrax) fed organic diets including dried Isochrysis aff. galbana (T-ISO). Three test isoproteic (50% DM) and isolipidic (18% DM) diets were compared. All preparations were formulated using "organic" ingredients. Isochrysis aff. galbana was incorporated to replace 10% (T- ISO10) and 20% (T- ISO20) protein supplied as dried fish trimmings which were the major protein source in the control diet (ORG).
