Evaluación de probióticos y ácidos orgánicos para el control del hongo microsporidio (Enterocytozoon hepatopenaei) y su incidencia en el rendimiento del camarón (Litopenaeus vannamei) en el cantón Pedernales en el año 2024.

Abstract

This research was to evaluate the efficacy of probiotics and organic acids in reducing the prevalence of the microsporidian fungus (Enterocytozoon hepatopenaei, EHP) and its impact on the productive performance of white shrimp (Litopenaeus vannamei). The research was carried out in ponds located in Cojimíes, Pedernales, applying treatments with different combinations of probiotics (Epicin pill, Aquablend pill, Protec, Citropac) and the organic acid Formicin. A randomized block experimental design was used to evaluate the incidence of the fungus and parameters such as growth rate, survival and total biomass. Water physicochemical factors (temperature, pH, dissolved oxygen and salinity) were also monitored.Probiotic treatments significantly reduced EHP levels, especially in the first weeks. Epicin pill and Aquablend pill were the most effective, improving shrimp survival and growth. Formicin showed a homogeneous effect on EHP reduction, contributing to the stabilization of productive parameters. Improvements in total biomass, feed conversion and survival rates were observed in the treated groups. The use of probiotics and organic acids represents an effective and sustainable strategy to control EHP infections, promoting a more profitable and environmentally responsible aquaculture. This approach is key to address disease challenges in shrimp farming and optimize production in affected sectors such as Cojimíes.
