Table 4 Non-specific immune response of olive flounder (P. olivaceus) 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
