A 12-week feeding trial was carried out in fibreglass tanks to examine partial replacement of fish meal (FM) with poultry by-product meal (PBM), meat and bone meal (MBM) and blood meal (BM) in practical diets for gibel carp Carassius auratus gibelio (Bloch). Triplicate groups of fish (initial body weight 15.3 g fish−1) were fed eight isonitrogenous (crude protein: 37.5%) and isolipidic diets (crude lipid: 7%). The control diet is the commercial diet of gibel carp, which used 18% of FM as the sole animal protein source. In the other seven diets (Diet 2–Diet 8), 17–83% of FM protein was substituted by a blend of PBM and BM or a blend of PBM, MBM and BM. The final body weight and thermal-unit growth coefficient of fish fed the feeds in Diet 8 in which 83% of FM protein was replaced by the blend of 3% BM, 10% PBM and 5% MBM is significantly lower than Diet 1 (the control). The feed efficiency ratio in Diet 8 group is significantly lower than Diet 1, 2, 4 and 7 groups. The results of the present study indicated that a combination of PBM, BM and MBM can replace most of the FM protein and the FM level can be reduced to about 6% with satisfactory growth and feed utilization in practical diets for gibel carp.
