Fifteen sampling stations were evaluated in streams and rivers in the influence area of the pipeline PERÚ LNG in the departments of Ica and Huancavelica, for this physicochemical parameters of water were taken, habitat type described and aquatic macroinvertebrates were collected. The results of physicochemical parameters were acceptable to the development of aquatic macroinvertebrates, with dissolved oxygen values below the legal regulations in the Matagente and Pisco rivers during the dry season (May, 2010), which also aquatic macroinvertebrates were composed of 34 taxa, with a 3671 total abundance of organisms/m2, unlike the wet season (November, 2010), where aquatic macroinvertebrates were composed of 26 taxa, with a total abundance of 1623 organisms/m2. The most representative organisms were arthropods, mainly those belonging to the class Insecta. The stations between 3985 and 4210 ...

Se evaluaron quince estaciones de muestreo en quebradas y ríos en el área de influencia del gasoducto de PERÚ LNG en los departamentos de Ica y Huancavelica, para ello se tomaron parámetros fisicoquímicos del agua y se colectaron macroinvertebrados acuáticos. Los resultados de los parámetros fisicoquímicos fueron aceptables para el desarrollo de los macroinvertebrados acuáticos, con valores de oxígeno disuelto por debajo de la normativa legal en los ríos Matagente y Pisco, durante la época seca (Mayo, 2010), donde también los macroinvertebrados acuáticos estuvieron compuestos por 34 taxones, con una abundancia total de 3671 organismos/m2, a diferencia de la época húmeda (Noviembre, 2010), donde los macroinvertebrados acuáticos estuvieron compuestos por 26 taxones, con una abundancia total de 1623 organismos/m2. Los organismos más representativos fueron los artrópodos, ...

Ten bodies of water were evaluated in the Ventanilla Wetlands located in the Callao region, in Peru, in the months of March and August 2018. The objective was to study the community of aquatic macroinvertebrates and their application to determine the quality of Water. For this, physicochemical parameters were recorded in situ and a 500 µm D-net was used for the biological collection. The values of the physicochemical parameters were in accordance with what is recommended in the national regulations, except for electrical conductivity, which exceeded the limit in water bodies near the sea. The aquatic macroinvertebrates were represented by 17 taxa, including gastropods and arthropods, of which the former were the most abundant (85.5% in March with 2555 organisms/m2 and 74.2% in August with 4422 organisms/m2), and the latter, the most diverse. The Wisconsin Wetland Macroinvertebrate Bioti...
