Evaluación del impacto sobre el agua de las camaroneras, y en los esteros circundantes (Ecosistema de Manglar - Archipiélago de Jambelí

Abstract

Abstract: This work proposes an evaluation of the water quality of three shrimp ponds with their surrounding estuaries, located in the Jambelí parish, Santa Rosa canton, El Oro province. Shrimp producers were also consulted through interviews about input inputs and chemical products used during shrimp production, the active principle of each of these products was investigated to consider the parameters to be sampled and to determine the dissolution of pollutants found in shrimp ponds compared to estuaries. A sampling was carried out at the end of the shrimp harvest in summer, taking into account physical-chemical parameters of the water: BOD, COD, turbidity, pH, P, Fe, Mg, Zn, Ca, Mn, Ni, K, Se and Na, comparing the results obtained with the current environmental regulations in Ecuador, showing that the shrimp farm No. 3 (C3) complies with most of the parameters within the maximum percentages allowed, while, for the estuaries, the estuary n 1 (E1), compliance record only in 2 of the 7 parameters analyzed, which can generate negative environmental impacts on water.
