Cría de camarón en cautiverio litopenaeus vannamei utilizando dos tipos de bacterias en el alimento

Today in day the methodology, to control pathological problems, it has considered alternative as the use of microorganism probióticos (bacterias, yeasts) in the cultivations of shrimps with the purpose of combatting harmfuls bacterias, also achieving this way to stimulate the immunologic system of the shrimp. The probióticos allows us to work in the shrimp cultivation with smaller risk, since these when they are prepared in correct form and applied in dose and adapted frequency, it diminishes the risk of illnesses, therefore one can obtain bigger survival, better increment of weight, among other advantages. In the market several probióticos types exist, with diverse bacterias, but not all guarantee us the wanted success, for that that, when demanding one or several of them, we should analyze in certain form their composition and characteristic. This investigative work was carried out in the camaronera "San Fernando" located in the canton The Guabo, parish Tilts, county of The Gold. It was used two ponds of 2.5 there is. each one. The outlined objectives were: To determine the incidence of the probióticos treatments on the increment of weight and to settle down with what probióticos type bigger survival is achieved. The statistical analysis for the increment of weight and the survival indicates that there is not significant difference for the two treatments. This investigation indicates that both products used for each one of the treatments, give the same result as for weight and production.
