At the hypersaline lagoons, there’s a greater concentration of salt.  The lagoons were modified for the production of salt.   Water from the Sea is controlled, then it’s evaporated for the extraction of salt.   Brine shrimp is abundant on the salt flats, they help with the production of salt and they are one of the factors for the reddish color of the flats.
