چکیده
The effects of Yarrowia lipolytica lipase 2 (YLL2) on growth performance, digestive enzyme activity and muscle nutritional components of Russian sturgeon (Acipenser gueldenstaedtii) were evaluated in a 56-day feeding experiment. Four experimental groups of fish with mean weight of 4.465 g were used in the study: Control group (0-control), Group 1 (1.0 g/kg YLL2), Group 2 (1.5 g/kg YLL2) and Group 3 (2.0 g/kg YLL2), respectively, with three repetitions. Fish fed diets with YLL2 at 1.0 g/kg showed the highest growth compared with that of the other groups (p<0.05). For nutrient apparent, docosahexenoic acid (DHA) and eicosapentenoic acid (EPA) concentrations in fish muscle of group which fed with 1.0 g/kg YLL2 increased 5.05% and 7.45% respectively, compared with that of control group (p<0.05). Considering the digestive enzyme activity, lipase and protease activity in liver, spleen and intestine of G1 fish was also significantly enhanced compared with that of control group (p<0.05). While, significant increase of amylase activity in intestine was only observed in fish treated with 2.0 g/kg YLL2. The present results suggested that YLL2 (1.0 g/kg) could be used as potential diet additives for aquaculture Russian sturgeon.
