Laguna El Llano
Laguna EL Llano is located in the state of Veracruz, between the Paraiso and Villa Rica beaches. It communicates with the ocean temporarily thanks to a channel located on the northeast that only opens up during rains, causing hyper-salinity conditions during low-water season. Constant environmental variations in the lagoon allow for the temporary and permanent establishment of different macro-crustaceans. These conditions also make El Llano the ideal home for many species, principally the crab Callinectes simillis and the white shrimp Penaeus setiferus, which have practically supported commercial fishing activities for years. A blockage caused by a pipe that crosses the lagoon in its entirety threatens the prosperity of these activities however, since it obstructs the normal flow of tides and the exchange of material present in the water, resulting in the loss of resources and affecting the livelihood of the fishermen and the ecosystem of the area. Coordinates: 19.66° N 96.41° W Selected Characteristics: (Castaneda and Contreras, 2001) Surface Area: 23 km2 Average Depth: 1.7 m Average Salinity: 22 ppt References: Castaneda L.O. and F.E.
