Test técnico de aplicación de bacterias aisladas desde el camarón en cultivo de camarón a campo abierto

Abstract

Abstract: The white shrimp is one of the most recognized and commercialized species globally, Therefore, the industry has innovated to provide a good quality product and high performance. One of the innovative alternatives has been the use of probiotics to improve your performance. In this work, the probiotic effect of strains of bacteria was evaluated in the growth and survival of Penaeus vannamei in culture. The bacteria Pantoea sp. and Shewanella xiamenensis, were applied for tests as potential probiotics in larvae. shrimp. Hemolysis and bacterial resistance tests were performed to rule out pathogenicity against humans. These strains were incorporated into the balanced pelleted and were tested in semi-intensive cultures of shrimp post larvae in stage three, evaluating their growth and survival. The results indicate that these bacteria do not carry out hemolysis. and neither do they generate bacterial resistance. The bacterium Pantoea sp., allowed to obtain greater larval growth followed by Shewanella xiamenensis compared to treatment control. However, since no statistically significant differences were observed, it was recommends expanding this type of study for a longer period of time, and consider measuring its effect on reducing shrimp susceptibility to diseases.
