Functional foods as stimulators of the immune system of Litopenaeus vannamei cultivated in Machala, Province of El Oro, Ecuador

Abstract:

Functional foods are of great importance in shrimp farming as substitutes of growth promoter antibiotics to increase productivity together with environmental impact minimization in the culture ponds. In this work we studied the behavior of some physical and immunological indicators in Litopenaeus vannamei after treatment with a symbiotic functional food composed by a mixture of fructoligosaccharides (FOS) and the yeast Saccharomyces cerevisae isolated from the Machala culture ponds (province of El Oro, Ecuador). As a result, a positive influence was observed in physical parameters such as water quality, nitrites, dissolved oxygen, pH and temperature as a result of the symbiotic treatment. An increase in the amount of proteins as well as the superoxide anion and the hemocytes count in the hemolymph was also observed, which indicates positives stimulation in the immune system of the treated animals with this functional food in the pelleteded feed, unlike no–treated controls.
