QUILICHE-DURAN, Jean Piere; ROMERO BOZZETTA, Luis; BAZAN BAUTISTA, Ronnel  and  HERRERA VEGA, Héctor. Descriptive study of the artificial lagoon Chorrillos located in the district of Huacho-Perú. Rev. Inv. Cs. Agro. y Vet. [online]. 2021, vol.5, n.15, pp.148-157. ISSN 2664-0902.  https://doi.org/10.33996/revistaalfa.v5i15.136.

The Chorrillos Beach Artificial Lagoon, located in Huacho, is an ecosystem that has been little studied and has a high number of tourists; therefore, it is important to know its current state. The objective of the research is to describe the geographic, demographic, biological, physical, chemical and microbiological aspects of the lagoon. The area of the North and South Zone was located with GPS, the physical and chemical components were measured using the water kit, for total coliforms the NMP technique and seeding in culture media for Vibrio cholerae and Salmonella spp. was applied, the biological diversity parameters were performed by 10 transects the count per individual, the plant and animal species were identified by taxonomic keys, the Margalef, Shannon and Simpson diversity index was calculated, the demographic values of the Huachana population of 2016 were obtained from INEI. The analyses reveal that there are parameters that exceed the LMP for water used for recreation, obtaining values of conductivity (1883 µS/cm) and total coliforms (2600 NMP/100 ml) in Z. South, pH of Z. North 7,25 and Z. South 7,37 and with 24,5 °C, the biological diversity in plants (1,31), fish (0,65) and birds (1,77), the biodiversity is low, however, in birds it presents a richness of species within the average comparing that of plants and fish. It is concluded that Z. South has a lower environmental and biological quality than the Z. North, which implies an impact on the ecosystem due to human activities.
