Comparison of Growth Performance and Muscle Nutrition Levels of Juvenile Siniperca scherzeri Fed on an Iced Trash Fish Diet and a Formulated Diet

To assess the possibility of using a formulated diet instead an iced trash fish for feeding spotted mandarin (Siniperca scherzeri), 20-week trial was conducted. The objective study to examine effects (FG) and (XG) on growth performance muscle nutrient composition fish. results showed that fed with XG had slightly higher survival rates, weight gain rate, fullness, hepatic index, viscera index compared those FG, although differences were not significant (p > 0.05). Additionally, in terms composition, FG group levels crude protein ash content < On other hand, fat opposite trend. Among seventeen amino acids analyzed, only lysine proline differed significantly between groups In muscle-hydrolyzed fatty acids, fifteen detected both groups, arachidonic acid being exclusive group. Furthermore, thirteen observed two lower saturated 0.05), while monounsaturated polyunsaturated EPA + DHA contents higher. This demonstrates potential as substitute rearing However, further optimization is necessary improve future research.
