With reference to the numerical frequency, the main itens to C. nobilis were youngs forms of Crustacea Decapoda (90,86%), Crustacea Amphipoda (3,97%) and Crustacea Decapoda Dendrobranchiata (3,8%} and to P. virginicus were youngs forms of Crustacea Decapoda (53,78%), Crustacea Copepoda Harpacticoida (27,76%) and Crustacea Amphipoda (14,24%).
