Effect of different sources and levels of carbohydrate (glucose and corn starch) on feed efficiency and carcass composition of juvenile Siberian sturgeon (Acipenser baerii)

The effect of glucose and corn starch at two levels of 15% and 30% for each source on growth performance and carcass composition of juvenile Siberian sturgeon (Acipenser baerii) was assessed. Two weeks after acclimatization to rearing conditions and basal diet, 120 juveniles (25.64 ± 2.80g) were randomly distributed into 12 fiberglass tanks (10 fish per tank, one fish per 35 liter) and fed for a period of 8 weeks with the designated diets in three replicates. The final weight and total length, percentage of body weight increase, specific growth rate, mean daily growth, protein efficiency ratio, condition factor, and FCR in fish fed 15% corn starch showed better performance than other treatments (p>0.05). A significant difference in HSI was seen between fish fed 30% corn starch with fish fed 15%glucose (p0.05). The highest content of carcass protein was seen in 15% corn starch that was significantly different from 15% and 30% glucose treatments (p
