The feeding ecology of penaeid shrimp in tropical lagoon-estuarine systems

Shrimps are an important resource in coastal lagoons because they use these ecosystems for their development. Although some authors classified the Penaeidae as detritivores, it was shown that their diet comprises a greater variety of food items. Many authors had reported that shrimps have a diversif...
