| The Lagoa do Peixe ("Peixe's Lagoon") is located between Atlantic Ocean and Lagoa dos Patos and is 30 Km long and 0,5-2,0 Km wide (31º13'S, 50º55'W -31º26'S, 51º09'). For one year, the composition and distribution of Crustácea Decapoda were analyzed monthly (from July/1994 to June/1995), in seven subareas (terrestrial border and aquatic area) and physical and chemical parameters (depth, salinity, sediment texture, oxygen in water, organic material of sediment and water temperature) were registered. Decapoda from the families Grapsidae, Ocypodidae, Portunidae (Brachyura), Diogenidae (Anomura) and Penaeidae (Penaeidea) were captured. Chasmagnathus granulata Dana 1851 was found ali months near the canal connecting Atlantic Ocean and Lagoa do Peixe, but inside... |

| The Hepatus pudibundus (Herbst, 1785) juvenile development was studied in laboratory, under the morphological and systematical stand points. The eight early juvenile stages were obtained from larvae hatched from eggs of two ovigerous females, collected at the northern coast of the State of São Paulo, Brazil. The experiments were carried out in a climatically controlled room at 25 ± 1°C, and steady saltness of 34. The youngs were maintened individually and food consisted of Artemia sp. nauplii and fragments of fish muscle.The first juvenile stage were particulary drawn and described. For the remaining juvenile stages the most representative frameworks were picked out, which allowed the characterization of the first eight stages. According to juvenile... |

| Uca (Minuca) burgersi Holthuis, 1967 was studied in the laboratory under the morphological and systematical stand points. One experiment was carried out involving 100 larvae, derived from one ovigerous female collected in the north coast of the State of São Paulo, Brazil. The experiment were carried out in a climatically controlled room at 25±1ºC and steady saltness of 34 The larvae were maintened individually and food consisted of rotifers (Brachionus plicatillis) in the first stage and Artemia sp. in the last stages. Uca (Minuca) burgersi have five or six zoeal stages and a megalopa one. All larval stages were drawn and described in detail. Tables where the morphological characteristic of each stage of the studied specie was described are also included.... |

| The larval development of Cyrtograpsus angulatus Dana, 1851 was studied in laboratory through eggs hatched from ovigerous females collected in mole of Rio Grande, Rio Grande, State of Rio Grande do Sul, Brazil. Three experiments (A, B, C) were carried out involving 250 larvae, derived from three ovigerous females. The experiments A and B, were carried in a climatically box with temperature among 22 and 25ºC, and salinity among 32 and 34. The experiment C in a room without controlled temperature, in a constant salinity of 30. The larvae were maintained individually and food consisted of rotifers Brachionus plicatillis Müller, 1786 and microscope algae Tetraselmis sp. The development of C. angulatus Dana, 1851 comprises five stages of zoea and one... |
