The effect of two concentration of an aqueous extract of the San Pedro Daisy, (Lasianthaea podocephala) roots, on the water quality, physiological condition and production parameters of the white Pacific shrimp, Litoenaeus vannamei, farmed under intensive laboratory conditions, were evaluated. Two treatments and a control were considered T1 (1 mL of extract per aquarium); T2 (3 mL of the extract per aquarium), and C (control, 0 mL of the extract). No negative effects of the treatments on water quality parameters were observed, being into the acceptable ranges and without significant differences.  Some of the production parameters such as final biomass and FCA were slightly better in the treatments using the extract. The concentration of haematic metabolites indicate that shrimp from treatments with the extract were under better conditions, indicated by the levels of protein and cholesterol in the muscle. However, it is necessary additional studies to evaluate at molecular level the active ingredients of the root extract in order to have most information for the potential use of the plant.
