Este estudio tuvo como objetivo evaluar el efecto de diferentes concentraciones de cromo (0.0 (control), 1.0, 5.0, 10.0, 15.0 y 30.0 mg/L) en el consumo de oxígeno y excreción de amonio en tilapia del Nilo (Oreochromis niloticus) de agua dulce, ya que esta especie tiene un interés alimenticio y económico en diferentes comunidades del país. Este estudio se realizó utilizando 42 peces juveniles de tilapia de un peso entre 1.0 y 3.0 gramos, los cuales fueron colocados en seis peceras con diferentes concentraciones de cromo. Después de 4 horas de exposición, se trasladaron a un sistema con recirculación de agua y en respirómetros individuales. Para cada concentración se utilizó un grupo de 7 peces, a los que se determinó el consumo de oxígeno y la excreción de amoníaco en cada respirómetro. Los resultados mostraron que al aumentar la concentración de cromo en el agua (p &lt; 0.05), disminuyó el consumo de oxígeno hasta un 62.8% de 0.4168 mL/g/L en el grupo control a 0.1550 mL/g/h en la concentración de 30.0 mg/L de cromo. La excreción de amonio fue mayor (p &lt; 0.05), después de haber sido expuestos los peces a una concentración de 1 mg/L de Cr6+.]]></p></abstract>

This study aimed to evaluate the effect of different chromium concentrations (0.0 (control), 1.0, 5.0, 10.0, 15.0 and 30.0 mg/L) on oxygen consumption and ammonium excretion in freshwater tilapia (Oreochromis niloticus), since this species has a nutritional and economic interest in different communities of the country. This study was carried out using 42 juvenile tilapia fish weighing between 1 and 3 grams, which were placed in six tanks with different chromium concentrations. After 4 hours of exposure, they were transferred to a system with recirculating water and individual respirometers. For each concentration, a battery of 7 fish was used, to which the oxygen consumption and ammonia excretion of each respirometer were determined. The results showed that by increasing the concentration of chromium in the water (p &lt; 0.05), oxygen consumption decreased up to 62.8% from 0.4168 mL/g/L in the control group to 0.1550 mL/g/h in the concentration of 30.0 mg/L of chromium (VI). The ammonium excretion showed the highest concentration (p &lt; 0.05), after the fish were exósed to having been exposed to a concentration of 1 mg/L of Cr6+.]]></p></abstract>
