📋 Tender Overview
With the objective of knowing the environmental state of the sea and evaluating the health of the coastal marine ecosystem, the Institute of the Sea of Peru (IMARPE) through its decentralized headquarters in Huacho recently carried out monitoring of water quality in the bays of Huacho, Carquin, Vegueta and Chancay-Chacraymar.
The evaluation, carried out during the closed period of the industrial anchovy fishery, allowed us to analyze the influence of various factors that can affect the marine environment, such as local oceanographic dynamics, wastewater discharge and the contribution of continental waters from the Chancay and Huaura rivers.
During monitoring, water samples were collected on the surface, bottom and coastal edge area. These samples allowed physical, chemical and microbiological parameters to be recorded.
Likewise, high concentrations of dissolved oxygen were recorded on the surface, which was associated with the presence of a green tide, generated by the proliferation of the phytoflagellate Eutreptiella gymnastica Throndsen 1969, a microscopic organism from the euglenophyta group.
On the other hand, specialists observed a lower water transparency in the bays of Chancay and Huacho, a situation that would be related to the increase in river flow due to the rains recorded in the central mountain range, as well as with discharges from local underwater emitters.
This monitoring is part of the permanent work carried out by IMARPE to generate updated scientific information on the state of the coastal marine ecosystem. The results contribute to strengthening the sustainable management of the bays and promoting the enhancement and protection of their resources against natural factors and human activities that can affect their environmental balance.
