Biometric and reproductive aspects of Palaemon pandaliformis (Stimpson, 1871) from Ratones Mangrove, Florianópolis, Santa Catarina, have been investigated. Individuals were monthly collected from August, 91 to July, 93 and the temperature and salinity registered. Biometry, sex-ratio, sexual maturity, fecundity and reproductive cycle have been determined. The temperature showed defined temporal distribution. This species presents animal reproductive cycle, relatively high individual and populational fecundity, and the ovigerous females were larger than males and other females of the same species. |

Biological aspects of palemonids, collected from March, 91 to December, 95 in the Ratones Hidrographic Basin, Florianópolis, Santa Catarina, have been investigated. Individuals of different sizes of Macrobrachium acanthurus (Weigmann, 1836), Macrobrachium carcinus (Linnaeus, 1758), Macrobrachium olfersii (Weigmann, 1836), Macrobrachium potiuna (Müller, 1880), Palaemonetes argentinus Nobili, 1901 and Palaemon pandaliformis (Stimpson, 1871) were registered. These prawns, showed reproductive strategies, typical of the Palaemonidae (Rafinesque, 1815), associated to species particularities, and seem to adapt to different environmental conditions. |

The embryonic development of four species of the family Palaemonidae was studied under laboratory conditions. Adults of Macrobrachium olfersi (Wiegman, 1836), Macrobrachium potiuna (Müller, 1880), Palaemon pandaliformis (Stimpson, 1871) and Palaemonetes argentinus (Nobili, 1901) were collected in Santa Catarina Island, Santa Catarina, Brazil and maintained at 26ºC. The following embryonic characters were analyzed: egg shape, yolk organization and cleavage plane, naupliar and post-naupliar appendages, stomodeum, optical lobes, eyes, telson, embryo curvature and the space occupied by the embryo in the egg. Different rates of development were observed for the four species, with M. potiuna showing the longest time of embryogenesis. The species studied followed... |
