Manejo estacional de los sistemas de producción de camarón en el ecuador

Abstract

Shrimp production in Ecuador is affected by various factors, such as ambient temperature variations during the winter and summer seasons. The seasonal management of shrimp production systems was investigated applying a quantitative research approach with evaluations of shrimp growth and survival rate. The ANOVA test identified significant differences (p<0.001) in the weekly growth rate of shrimp during the two seasons. In winter, applying a two-phase culture system, the weekly growth rate was 1.39±0.07 g/week, obtaining a final weight of 21±1.32 g in 103 days and a total production of 2004.42±351.68 kg/ha. In summer, in a three-phase culture system, the weekly growth rate was 1.21±0.09 g/week, and final weight of 23±1.16 g, in 94 days and a total harvest production of 1625.22±294.46 kg/ha. A multi-phase production system sustained the shrimp production capacity during low seasonal temperatures in the summer season.
