Abstract: This study was designed to assess the use of microbial fermented, non-dairy creamer as a new aquaculture feed ingredient for juvenile red sea bream Pagrus major (Temminck & Schlegel, 1843) in a closed recirculating system. Fermented non-dairy creamer was supplemented 15, 10 and 5% in the diets (Diet 2, Diet 3, Diet 4). A diet with fish meal was used as a control (Diet 1). A steady growth was observed in all the treatments. The satisfactory weight gain was found in the fermented creamer diets. It was observed that the protein and lipid percentage was increased in the fermented product compared to the raw creamer. A significantly higher value of total final weight, final mean weight gain and daily weight gain was observed in the 15% microbial fermented, non-dairy creamer diet (Diet 2). Gross yield, specific growth rate (%) and growth rate (%) was found highest in the 15% fermented non-dairy creamer, compared to other treatments (P<0.05). The protein percentage in the body carcass was almost similar to all the treatments. The carcass lipid percentage increased significantly in the higher level of the fermented creamer diet compared to the control. This preliminary study has demonstrated that microbial fermented creamer could be an important aquaculture feed ingredient and however, more research needs to be done on different species of fishes.
