Dinâmica da alimentação natural de Callinectes danae Smith (Decapoda, Portunidae) na Lagoa da Conceição, Florianôpolis, Santa Catarina, Brasil
From March/91 to February/92 monthly collcction surveys were carried out to obtain basic information about the dynamics of feeding and trophic spectrum of C. danae Smith, 1869. A total of 456 males and 527 females were caught. The diet of the species was not sex related. The trophic spectrum of C. danae is composed by a high number of items. The 35 items were assembled in 14 categories and the feeding index was applied. Mollusca, Polychaeta and Crustacea were observed to be basic elements in the species diet, Osteichthyes and MOND appear as secondary resource whereas vegetal material were found to be of less importance.
