The objective of this study was to evaluate the performance of Litopenaeus vannamei postlarva submitted to different substitution levels of fish meal protein by meat and bone meal protein. A completely randomized design, in a 4x2 factorial arrangement was used. The first factor was substitution levels of fish meal protein by meat and bone meal protein (0, 25, 50 and 75%); and the second factor was the use of a commercial attractant (with and without). The system consisted of 40 plastic boxes with 50 L each, provided with aeration, biofilter and shelter for the shrimps, with water from a low salinity well combined with 1% of effluent from low salt water dessalinization. It was evaluated shrimp final weight, weight gain, feed consumption, feed conversion rate and survive. It was observed that shrimp performance decreased with the increasing on substitution levels of fish meal protein by meat and bone meal protein; and the presence of commercial attractant on feeds resulted on higher final weight and weight gain, in relation to feeds without commercial attractant.
