Dosificación del aditivo nufoaqua grow plus en Litopenaeus vannamei para contrarrestar el estrés y aumentar el crecimiento en camarones en cautiverio ubicado en la camaronera Coopas, cantón Arenillas, provincia de El Oro.

Abstract

The purpose of this project was to conduct research into a food additive as a natural growth promoter and to counteract stress in growing organisms. Larval culture and the knowledge that it is in the diet or food requirements are great theoretical support when understanding the needs of larvae, using the additive as an alternative in order to efficiently feed, growth and reduce stress due to different factors found within the shrimp crop, thus consisting of balanced food, diet with algae, artemia and supplements. The additive to be used contains natural, nutritious compounds, organic acids, which is directly added to the food with the help of a glue. The growth of larva is the product of a good food conversion that influences the speed of its growth, weight or achieving the maximum sizes immediately reaching the final stage, the brightness in its body and the activity when moving. The final results indicated that there was no significant difference with the control pool in terms of weight. However, it is remarkable the superiority of activity because there has not been any stress even in sudden temperature changes, the good indication of survival at the end of the production cycle. Finally in the harvest part, quite different results were obtained, leaving the difference between the pool with the additive and without the additive. It is very important and vital to permanently incorporate microbiological analyses of water, soil and larvae, to have as a technical tool and to know the characteristics of our swimming pools and complementing it with the diets that best suits to influence the growth of shrimp.
