This study is conducted to evaluate the effect of feeding frequency on growth, feed conversion ratio and survival rate of white leg shrimp (Litopenaeus vannamei) post-larvae in 56 days. Final mean weights obtained for 2 and 4 times/day (6.73 ± 0.09 g and 6.98 ± 0.15 g, respectively) were significantly lower than treatment 6 times/day (8.56 ± 0.16 g) (P
