Abstract: Nine-day-old sterlet (Acipenser ruthenus) larvae were reared for 21 days on one of three commercial diets with different protein and fat contents: Bio Kyowa, Aglo Norse, or Perla Larva Proactive. At the end of the experiment, the sterlet juveniles were sampled for histological analysis of the pancreas and evaluation of lipase, trypsin, and amylase activity. Fish fed the Bio Kyowa and Aglo Norse diets were the largest. Survival was highest in the Aglo Norse group. There were no differences between groups in histologi- cal analysis of the pancreas, and no histological anomalies. The highest lipase activity was observed in fish fed the diet with the highest lipid content (21%) - the Aglo Norse diet. Trypsin activity was higher in fish fed Bio Kyowa with a protein content of 55% than in fish fed Aglo Norse with a pro- tein content of 59%.
