Abstract

The effect of Echinacea purpurea and Uncaria tomentosa on growth performance, survival, WSSV prevalence, and immune response of Litopenaeus vannamei was evaluated under laboratory conditions. Powder of plants (PP) was sprayed onto feed (Nutrimentos Acuícolas Azteca S.A. de C.V.®, 35% protein) at 0, 0.5, 1.0, 2.0, and 4.0g kg feed -1. A bioassay, performed with treatments in triplicate, was conducted for 30days. Feed supplemented with plants did not enhance growth and survival. However, PP decreased the prevalence of WSSV in shrimp treated (83.3, 50.0, 16.6, and 8.3%) as compared with the control group (100%). The PP significantly increased the activity of phenoloxidase in plasma in shrimp fed 4g kg feed -1. The results indicate that PP at concentrations of 2.0 and 4.0g kg feed -1 is a suitable feed additive against WSSV in shrimp with low viral load.
