Abstract
El objetivo de la presente investigación fue evaluar la calidad de agua del río
Chillán mediante el uso de un índice biótico de familias basado en macroinvertebrados bentónicos y comparar los resultados con los obtenidos anteriormente por Figueroa (2004) y Figueroa y otros (2007), el estudio se basó en analizar los cambios presentados en las estaciones de muestreo y en el conteo de familias encontradas en cada estación para determinar la condición en que se encuentra cada tramo del río para esto las muestras fueron tomadas mediante una red surber y posteriormente analizadas bajo lupa en laboratorio. Los resultados arrojaron que las estaciones de muestreo sufrieron cambios debido a distintas actividades desarrolladas durante los años anteriores y la calidad del agua del río continua en calidad de mala a muy mala y se encuentra dentro de los rangos de resultados presentados por Figueroa (2004) y Figueroa y otros (2007).
The objective of this research was to assess the water quality of the Chillán River using a family-based biotic index based on benthic macroinvertebrates and to compare the results with those obtained previously by Figueroa (2004) and Figueroa et al. (2007). The study focused on analyzing changes at the sampling stations and counting the families found at each station to determine the condition of each river segment. For this, samples were collected using a Surber net and subsequently analyzed under a microscope in the laboratory. The results indicated that the sampling stations experienced changes due to various activities conducted in previous years, and the water quality of the river continues to be poor to very poor, falling within the ranges of results reported by Figueroa (2004) and Figueroa et al. (2007).
