Abstract

The objective of this work was to evaluate the performance of Litopenaeus vannameifed different levels (0, 25, 50, 75, and 100%) of soybean protein concentrate (63.07% crude protein, CP) to replace fish meal-by product (61.24% CP). The study was conducted in clear water in fifteen 800 L tanks equipped with aeration systems, constant heating (29 oC), and daily water exchange (30%). Each tank was stocked with 37.5 shrimp/m3 (3.03±0.14 g). Feed was supplied four times a day, at 6% of the initial biomass, adjusted daily. After 42 days, the weight gain of shrimp fed diets with 0 and 25% protein replacement was higher than that observed in shrimp fed 100% replacement, and there were no differences among those fed the other diets. Feed efficiency and survival did not differ among shrimp fed different protein replacements. There was a negative linear trend for growth parameters and feed intake as protein replacement with soybean protein concentrate increased. Fish meal by-product can be replaced by up to 75% of soybean protein concentrate, with no harm to the growth of Pacific white shrimp.

Summary

Introduction

Success in L. vannamei production is related to proper management practices, water quality, breeding, and efficient diets. Fish meal is currently one of the major sources of animal protein used in diets for marine shrimp (Sá et al, 2013). Fish meal production has declined by an average of 1.7% per year over the past 15 years (1994-2009), limiting the supply of this input and increasing its cost (FAO, 2012). This reality can make the production of many aquatic species economically unfeasible. To solve this problem, studies have been conducted to evaluate the replacement of fish meal protein by other sources of animal and/or vegetable origin (Gatlin III et al, 2007)
