Objetivo: Identificar el contaminante más relevante que afecta la calidad de las aguas del río Huaura. Métodos: Se efectuó una recopilación bibliográfica de todos los trabajos similares efectuados a la fecha cuyos resultados nos permitan identificar el impacto de los elementos de contaminación orgánica y determinar si las aguas, sobrepasan los límites máximos permisibles para metales pesados La caracterización fisicoquímica y microbiológica se efectuó procesando los resultados de las estaciones fijadas por Digesa en sus monitoreos y los efectuados por la Universidad local. Resultados: Se encontró que las aguas de estos ríos presentan serios problemas fisicoquímicos, en todas las estaciones de muestreo, tal como se aprecia del resultado de las identificaciones de los análisis de las muestras por el laboratorio Envirolab Perú y Rovill Ingenieros efectuadas por la Univers...

The objective of this study was to establish the presence of Anisakis spp in freshwater fish in the El Paraíso wetland, in Huacho, Peru, due to massive parasitism observed in previous studies of identification of aquatic communities. The parasites were sampled in three common species in the wetland. Results showed 90, 75 and 66% of fish Dormitator latifrons, Mugil cephalus and Lebiasina bimaculata were infested with Anisakis parasites in larval stage L3, respectively. In addition, 50 and 25% of D. latifrons and M. cephalus, respectively, presented larvae of this parasite in the liver and visceral cavity. On macroscopic inspection, the Anisakis spp larva is observed spirally attached to the liver or disseminated in the intestines. Microscope images show the penetration tooth and the mucron, specific characteristics in the identification of Anisakis larvae. The present study is a first re...
