Dynamic of decapod crustacean larvae on the entrance of Guanabara bay [PDF]
Brazilian Archives of Biology and Technology, 2002 In the present study, we observed seasonal variations in the density of decapod larvae as well as changes in density related to diurnal and tidal cycles. Among the decapod larvae collected, portunids and grapsids were the most abundant, especially during nocturnal ebb tides and near the surface. The same results were obtained in late winter (September)
