Acuabio 1 , an enhancer of the immune system in Litopennaeus vannamei shrimps

Acuabio 1 is a mixture of proteins and essential amino acids that exerts a stimulating effect in the development of aquatic organisms. It synchronizes and accelerates fish and shrimp larvae growth on early developmental stages, as well as increases the development and size of these animals. In this work, the stimulating effect of Acuabio 1 on the immune system of Litopennaeus vannamei shrimps was demonstrated by obtaining (5.4 x 10 hemocytes/mL) greater than the control group (4.3 x 10 hemocytes /mL). The hemolymph of treated animals showed higher lectin titers (16) than the control group (8). Animals treated with Acuabio 1 increased their phenoloxidase and peroxidase activities, indicating an enhanced oxidative defense. Furthermore, Acuabio 1 decreased the number of Vibrio spp. and Pseudomonas spp. colony forming units in the culture medium, suggesting a possible prebiotic function. All these properties make Acuabio 1 very attractive to improve the production, survival rate and quality of shrimp larvae.
