The present study evaluated the impacts of powdered Astragalus membranaceus extract (AME) on growth, physiological responses, and serum immunity Pangasianodon hypophthalmus juveniles. Four test diets were formulated to include varying AME levels as 0.0 (control), 1.5 (AME1.5), 3.0 (AME3.0), 4.5 (AME4.5) g/kg. Fish weighing approximately 11.50 g stocked into four triplicate groups hand-fed three...

Taurine is a ? sulphonic amino acid and conditionally essential for many fish species. In the present study, effect of dietary taurine (tau) on Pangasianodon hypophthalmus fry (initial mean weight 0.8 ± 0.6 g) was evaluated by feeding six isonitrogenous (370 g/kg crude protein) isolipidic (100 lipid) casein-based purified diets with graded levels tau at 0 (basal diet), 5, 10, 15, 20, 25 feed.
