¹RCP, ratio of fish meal consumption to fish production. ¹R: reference diet; P16: poultry by-product meal (PBM) replaced 60% of the fish meal in diet R; P8 and C (the same treatment): PBM replaced 80% of the fish meal in diet R; C5 and C10: PBM replaced 80% of the fish meal in diet R with 5000 and 10000 mg/kg curcumin supplementation, respectively. Data are presented as mean ± SD (n = 3). The superscripts present the results of Duncan’s test between R, P16, and P8 (capital letters) or between C, C5, and C10 (small letters). The data in the same column with different superscripts are significantly different ().
