Table 2 Growth performance and feed utilization of olive flounder (P. olivaceus, initial BW: 19.5 g) fed the five experimental diets for 10 weeks. The diets were added with graded levels of taurine by 0, 0.25, 0.5, 1.0, and 1.5% (control, T1, T2, T3, and T4, respectively)

From: Taurine supplementation in diet for olive flounder at low water temperature
