Ozcan, F. and Tasbozan, O. 2022. The effects of dietary protease enzyme on growth performances and digestive enzyme activities of gilt head sea bream (Sparusaurata). Animal Nutrition and Feed Technology, 22: 95–106. With this study, the effects of adding different levels of protease enzyme (0.5, 1 and 1.5 g/kg diet) on sea bream (Sparus aurata), growth performance, digestive enzyme activity and body chemical compositions were investigated. A total of 840 sea bream juveniles with an average initial weight of 7.72+0.05 g were fed eight different diets. As a result of the study, the final weight (FW) in the G6 (0.5 g/kg, 50% protein) group was 52.38 + 0.70 g, the specific growth rate (SGR) was 3.18 + 0.02, the feed conversion rate (FCR) was 1.17+0.03 as compared to other groups (P<0.05). However, it was observed that the group with the best digestive capacity was G6. Protease, trypsin and alkaline phosphatase activities supported growth and their activity increased during the trial. In the amylase, lipase and aminopeptidase activities, a decrease detected during the trial.
