Abstract: The objective of this experiment was to evaluate three fish meal sources added to diets for the shrimp, Fishmeal quality is major important consideration for the aquatic animals especially shrimp Litopenaeus vannamei, however, it varies widely depending on raw material sources and processing methods. A ten-week feeding trial was conducted using six formulated diets to examine effects of fishmeal quality on growth performance, protein digestibility in Litopenaeus vannamei. Each test diet was fed four times daily to four groups of shrimp with an average initial weight of 2 g shrimp -1. The shrimp fed D-1 (FM-1) and d-2 (FM-2) feed attained high body weight, specific growth rate with the best feed conversion ratio (FCR). Growth of shrimp fed D-3,4 (FM-3 & 4) was less than D-1 (FM-1) because containing diets were inferior to those of FM-1 fed group. The d-5 (FM-5) diet-fed group showed the slowest growth and feed utilization efficiency than all the other groups.
