| Gastropod shells occupied by hermit crabs are an important attachment substrate for epifauna, and these shells are often damaged. The present study aimed to characterize the epibionts and extent of damage for gastropod shells occupied by the hermit crab Loxopagurus loxochelis (Moreira, 1901). Samples were collected monthly over a period of one year (from July 2002 through June 2003), in the Caraguatatuba and Ubatuba regions, on the northern coast of São Paulo, Brazil. The sampling was performed using a fishing boat equipped with double-rig nets. The shells were identified and weighed. Loxopagurus loxochelis occupied 14 gastropod shell species in Caraguatatuba and five in Ubatuba. In the two areas, approximately 55% of these gastropod shells bore epibionts,... |

| The present study focused on the decapod fauna of the fluvial-estuarine environment of the Guajará Bay, in the Brazilian state of Pará, where specimens were collected monthly from six sites, from May 2006 to April 2007. A total of 6,793 specimens were captured, belonging to 11 species of crab and shrimp: eight palaemonids - Macrobrachium amazonicum (Heller, 1862), Macrobrachium surinamicum Holthuis, 1948, Macrobrachium carcinus (Linnaeus, 1758), Macrobrachium rosenbergii (De Man, 1879), Macrobrachium spp. 1-4 -, one portunid - Callinectes bocourti A. Milne-Edwards, 1879 -, and two trichodactylids - Sylviocarcinus devileii H. Milne-Edwards, 1853 and Sylviocarcinus pictus (Milne-Edwards, 1853). While no significant differences were found in the ecological... |

| The reproductive aspects of the freshwater shrimp Potimirim glabra (Kingsley, 1878) were studied from September 1997 to February 1999. Monthly, samples were collected with sieves, on the river edge, under the edging vegetation or in small pools. At the laboratory, shrimps were sexed and measured in their total lenght, from the tip of the rostrum to the end of telson with precision callipers. The ovigerous shrimps were separated and counted for fecundity determination. The eggs diameter was measured with calibrated stereomicroscope. A total of 3281 shrimps were collected, among which, 47% male, 46% female (13.4% ovigerous females) and 7% young shrimps. The Sex ratio was 1:1. Ovigerous females were present during all seasons, but the reproductive peak... |

| The crustaceans of the genus Aegla Leach, 1820 are found in streams, rivers and lakes from Franca, São Paulo, Brazil (20º60'S, 47º40'W), to Ilha Madre de Dios, Chile (50º01'10"S, 75º18'45"W) in South America. The growth and cheliped asymmetry of Aegla platensis Schmitt, 1942 were analyzed. The animals were collected from July 1997 to September 1998 at Arroio do Mineiro, Taquara, Rio Grande do Sul, Brazil (29º46'S, 50º53"W). The sex, length, width of the carapace and the total weight of the crab were registered. And after that, the animals were returned to the stream. In the statistical analysis von Bertalanffy's model was used. The growth curves in length (mm) of males and females are described, respectively, by the following equations: L1 = 17.39 [1 - e... |

| 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 most important appendages of the first juvenile stage were analysed: first and second antenna, mandible, first, second and third maxillipeds, first and fifth pereopods, telson and uropods. Setal formula for the first stage and setae characteristics are presented. |

| A study of the annual abundance fluctuation, temporal distribution and size composition of Aegla castro Schmitt, 1942 was carried out at the Buraco do Padre, Quebra-Perna River, Tibagi River Basin, in the municipality of Ponta Grossa, Paraná State. The samplings were done monthly, from February/97 to January/98 with the aid of a hand net and screens at three stations, under an effort of 120 minutes. The average air temperature ranged from 15.0ºC (May, July, September and October) to 24.3ºC (December and January), and the water temperature from 15.8ºC (July) to 22.3ºC (December). The dissolved oxygen oscillated from 95.7% (March) to 100. 2% (August) saturation, and the pH from 6.1 (July) to 7.2 (September). The water flow speed varied from 0.2 m/s to 1.2... |

| 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.... |

| Neste trabalho é apresentada a fauna de crustáceos decápodos associados a esponjas coletadas ao largo da cidade de Fortaleza, Ceará, Brasil. As esponjas foram obtidas através de mergulho autônomo, realizado no Parque Estadual Marinho " Pedra da Risca do Meio" . No laboratório, os poríferos foram identificados e os crustáceos retirados e etiquetados de acordo com a esponja em que foram encontrados. Nove espécies de esponjas foram coletadas e 14 espécies de crustáceos identificadas. Os Crustáceos da família Alpheidae foram os mais representativos, com seis espécies, seguidos pelos decápodos das famílias Mithracidae e Porcellanidae, com duas espécies e Palaemonidae, Pilumnidae, Pseudorhombilidae e Xanthidae, com uma espécie. A partir do presente registro, as... |

| The project PRS-GEDIP was carried out in the Rio Grande do Sul coast, with some few stations off Maldonado (Uruguay), by means of a convention between Instituto Oceanográfico USP (IOUSP) and the Grupo Executivo do Desenvolvimento da Indústria da Pesca (GEDIP) of Rio Grande do Sul. The purpose of this project was the acquisition of data in order to have a better biotic and abiotic characterization of the southern Brazilian coast. Among the Galatheidae, about 1200 specimens of the genus Munida Leach, 1820 were collected, including five species as follows: Munida flinti Benedict, 1902; M. forceps A. Milne Edwards, 1880; M. iris A. Milne Edwards, 1880; M. irrasa A. Milne Edwards. 1880 and M. longipes A. Milne Edwards, 1880. The description, material examined,... |
