Macroinvertebrates have been used for decades to evaluate water quality, using measures of diversity, biotic indexes and comparative analysis. The taxonomic level of family allows a general interpretation of the ecological quality of a fluvial system, and is possible to infer the quality of these...

The effects of climate change and the severe anthropization of local river systems have contributed to the alteration of ecological processes, affecting the water quality in these systems and thus generating conditions for the emergence of algal species. In this context, the object of the present...

Genypterus chilensis is a marine fish of high gastronomic demand, whose capture has declined in recent years due to overfishing. In the development of the farming technology, high mortalities were obtained during egg incubation. The objective of this study is to contribute to the knowledge of fec...

The water quality in the upper and medium zone of Traiguén river in the Araucanía region was studied in the present work. Physico-chemical and microbiological parameters were measured at six sample stations in a zone that goes from close to the origin of the river to the limits of the city of Vic...

A healthy body of freshwater can provide numerous benefits to the society, although currently, the degradation of such ecosystems has been increased due to the establishment of urban areas along its riverbanks. In this study we analyzed the spatial effect of these zones on the water quality, usin...
