Chalacatepec Lagoon
Hydrology and Restoration
The natural in and outflow of fresh and saltwater has been compromised through the filling of wetlands and the installation of channel doors. Existing channels are overgrown and don’t allow water to flow easily. Erosion in the region has created siltation and low water levels. In close collaboration with the fisheries cooperative, ejido leaders, and state agencies, we are evaluating different models of restoration and the consequences of interventions. In the coming months, the first action will be the removal of plants and silt from the main channel. We are proceeding slowly on purpose, to avoid mistakes and to observe the changes caused by each intervention.
Shrimp Farming
This lagoon has the right conditions to support a natural shrimp harvesting program that would not interfere with the ecosystem or introduce chemicals. Essentially it could be developed into an exemplary shrimp production site that would produce food and income, while not harming the natural estuary. If the program is built within the framework of lagoon restoration, it will enable fishers to have one or two shrimp harvests per year and improve the fishing of high-value fish for the rest of the year.
The Sierra A Mar team is currently assisting with diagnostics and monitoring methods.
