Trypsin activity in pyloric caeca was statistically elevated in the fermented lupin groups compare to FRL0 group. Whole-body composition, amino acid content, and deposition showed no significant differences among groups. Fermented lupin did not suppress the immune system, and a slight immunostimulatory effect was observed at a 12.5 % inclusion level. No histopathological alterations were detected.

European sea bass juveniles, with an initial average weight: 18.9 g, were fed the experimental diets for 71 days in triplicate groups. Results indicated no adverse effects on key production indices when soybean meal was replaced partially or totally. Fermented lupin meal linearly improved feed utilization. Apparent digestibility coefficient of protein significantly increased in groups fed 12.5 % and 15 % fermented lupin, as did apparent digestibility coefficient of fat, compared to the FRL0 group. Trypsin activity in pyloric caeca was statistically elevated in the fermented lupin groups compare to FRL0 group. Whole-body composition, amino acid content, and deposition showed no significant differences among groups. Fermented lupin did not suppress the immune system, and a slight immunostimulatory effect was observed at a 12.5 % inclusion level. No histopathological alterations were detected. Overall, the results demonstrated the efficacy of solid-state fermentation process in enhancing lupin meal, highlighting its potential as a sustainable replacement for soybean meal in feed formulations for Mediterranean marine aquaculture species such us D. labrax.

The mean intensity encompassing the number of adults and larvae was 8.1 in treated vs 17.7 in control fish.
