Efecto de la disposición de los aireadores mecánicos sobre el perfil de oxígeno disuelto en estanques de cultivo de camarón

Abstract

Dissolved oxygen (DO), as one of the key physicochemical parameters directly affecting the water quality of an aquaculture pond, becomes a crucial factor in production. The deficiency of this factor can lead to high mortalities and imbalance in the water properties of the cultivation system. In this research, the study is focused on the effect of the arrangement of mechanical aerators (static and rotary aerators) in a traditional shrimp pond. The evaluation is aimed to assess how this arrangement affects the availability of DO in the pond. Data were collected regarding DO distribution in the vertical profile within the pond, with horizontal measurements taken every 3 meters up to a distance of 30 meters from the aerator, in both arrangements. The results are presented through descriptive statistics, examining the arrangement's effect over an 8-week period to gather sufficient data supporting the efficiency in DO incorporation by these two types of arrangements, revealing differences between them. The aerator arrangements showed varying results concerning the presence of DO in the vertical profile, with a DO incorporation difference of 15.76% and 6.38% for static and rotary aerators, respectively. It is concluded that higher DO incorporation was observed in the static aerator due to its blades maintaining efficiency in this process. In contrast, the rotary aerator experiences an efficiency loss of up to 59.49% due to its displacement, providing no additional benefit compared to the static aerator.
