Feeding ecology of juvenile marine fish in a shallow coastal lagoon of southeastern Mexico

Many species of marine fish use coastal lagoons during early stages of their life cycles due to the protection provided by their turbid waters and complex structure of the environment, such as mangroves and mudflats, and the availability of food derived from the high productivity of these sites. In...
