Abstract: Coastal lagoons frequently evolve toward total isolation behind sediment barriers. We studied the effects of natural tidal inlet closures on three Mexican coastal lagoons with different degrees of isolation. The physical and chemical changes have reduced the populations of shrimp, fish and mussels and are threatening the health of local human communities as stagnant water conditions develop. Conservation of lagoon environments requires human intervention and a holistic approach to the management of their biological productive systems.
