dc.description | La actividad camaronera es de gran relevancia para el comercio exterior, razón por la cual ha aumentado en el Ecuador en los últimos años, las piscinas camaroneras se construyen en suelos de manglares y humedales, estos ecosistemas que son de importancia ecológica para el país y que están siendo afectados por el crecimiento de esta actividad. Es por ello, que este trabajo plantea la utilización de ensayos ecotoxicológicos de exposición forzada para evaluar el efecto de las aguas residuales del cultivo de camarón utilizando alevines de Guppy (Poecilia reticulata). Un ensayo de exposición forzada fue realizado para evaluar la potencial contaminación del agua residual de la camaronera. Una muestra de agua residual de una camaronera ubicada en el Humedal la Segua fue diluida con agua de bidón para obtener 4 tratamientos de exposición (25%, 50%, 75 y 100% de agua residual), más un control (0% de agua residual). Para la realización del ensayo se utilizaron peceras de 12x12x12 cm. En cada pecera se colocaron 6 alevines de Guppy con una talla promedio de 2,72 ± 0,2 cm. El ensayo tuvo una duración de 5 días, y cada tratamiento fue testado por triplicado. Todos los días de ensayo se llevó un registro de respuestas como: capacidad natatoria y mortalidad. Los resultados demuestran que la especie P. reticulata no presentó mortalidad ni perdida de la capacidad natatoria durante el ensayo. De forma, adicional un ensayo de exposición no forzada fue realizado para evaluar la sensibilidad de la especie durante su exposición al agua residual de la camaronera, quedando demostrado que esta especie mostró una respuesta de fuga desde la primera hora de exposición en todos los tratamientos de exposición. Palabras clave: Camaronera, humedal, agua residual. Abstract The shrimp activity is of great importance for foreign trade, which is why it has increased in Ecuador in recent years, shrimp ponds are built on mangrove soils and wetlands, these ecosystems that are of ecological importance to the country and that are being affected by the growth of this activity. For this reason, this work proposes the use of ecotoxicological tests of forced exposure to evaluate the effect of wastewater from shrimp culture using Guppy fingerlings (Poecilia reticulata). A forced exposure trial was conducted to evaluate the potential contamination of the shrimp's wastewater. A sample of wastewater from a shrimp farm located in the La Segua Wetland was diluted with drum water to obtain 4 exposure treatments (25%, 50%, 75 and 100% residual water), plus a control (0% residual water). Fish tanks of 12x12x12 cm were used to carry out the test. In each tank, 6 Guppy fingerlings with an average size of 2.72 ± 0.2 cm were placed. The trial lasted 5 days, and each treatment was tested in triplicate. Every day of the trial a record of responses was taken, such as swimming capacity and mortality. The results show that the species P. reticulata did not show mortality or loss of swimming capacity during the test. In addition, an unforced exposure test was carried out to evaluate the sensitivity of the species during its exposure to the shrimp's residual water, demonstrating that this species showed a leakage response from the first hour of exposure in all the treatments exposition.
