| The present paper aims to describe the temporal and spatial distribution of the composition and abundance of Decapoda larvae in the shallow waters around Arvoredo Marine Biological Reserve. Stomatopod occurrence is also discussed. Plankton samples were collected at five sites around the Arvoredo Island every two months for one year from May, 2002 to April, 2003. Thirty-nine morphotypes, 11 genus and 4 species (Artemesia longinaris Bate, 1888, Hexapanopeus schmitii Rathbun, 1930, Menippe nodifrons Stimpson, 1859 and Pleoticus muelleri Bate, 1888) were identified, among them only two morphotypes of Stomatopoda larvae, and the remainder Decapoda larvae. Brachyuran zoeae were the most abundant group and they were well represented by Portunidae and Xanthidae... |

| The contamination and distribution of organ ochlorinated compounds were considered in three crustacean species (edible crab, Cancer pagurus; spider crab, Maja brachydactyla; velvet swimming crab, Necora puber) from five sites along the coasts of Brittany and Normandy (Western and North-Western France). PCBs (16 single congeners), pp'-DDE and HCB were measured in hepatopancreas, gonads and muscle: in all, 175 samples were analysed. The spider crab was the only species found in the five sampling sites, thus enabling comparison between areas. Specimens from Antifer were much more contaminated (Sigma(16)PCBs in hepatopancreas = 2000-4000 ng g(-1) dry weight) than those from other sites (50-1000 ng g(-1) d.w.). Among all the three species, the spider crab... |

| Chlordecone is a very persistent insecticide used in banana plantations of the French West Indies between 1972 and 1993. Chlordecone residues were found in inland water, in agricultural and freshwater products, and in marine organisms. This pollution has become of great concern in 2007. Therefore, a governmental action Plan was launched to better assess the pollution and to improve the consumer’s protection. Within this plan, 1048 samples from 69 different species of marine fishes and crustaceans were collected all around both the Guadeloupe and the Martinique Islands and analyzed. The results confirm the presence of chlordecone in marine organisms, with highly variable concentrations (from the detection limit to 1000 μg.kg-1). In 17.9 % of the samples,... |

| Several species of crabs from hydrothermal vent sites in the Pacific Ocean Were found to be infested by small, symbiotic nemertean worms. Worms occurred on both male and female crabs, and were located in mucous sheaths adhering to the axillae between the limbs of males and females, the setae of the pleopods of females, and the sterna of infested male and female crabs. Only juvenile and regressed adult worms were observed, primarily because no ovigerous hosts were examined. Similar species of worms mature by eating eggs, then regress or die after host eclosion. Based on the size of the worms from file vent crabs, their habitus with their crustacean hosts, the presence of accessory stylet pouches, and the presence of a single stylet on a large basis... |

| In this comparative study, osmoregulatory mechanisms were analyzed in two closely related species of palaemonid shrimp from Brazil, Macrobrachium pantanalense and Macrobrachium amazonicum. A previous investigation showed that all postembryonic stages of M. pantanalense from inland waters of the Pantanal are able to hyper-osmoregulate in fresh water, while this species was not able to hypo-osmoregulate at high salinities. In M. amazonicum originating from the Amazon estuary, in contrast, all stages are able to hypo-osmoregulate, but only first-stage larvae, late juveniles and adults are able to hyper-osmoregulate in fresh water. The underlying molecular mechanisms of these physiological differences have not been known. We therefore investigated the... |

| Although many studies have investigated the benthic environment of temperate marine waters, little is known about the acoustic behaviour of the organisms in these habitats, particularly crustaceans. This study focused on the acoustic behaviour of large crustaceans in NE Atlantic coastal regions. A total of 11 crustacean species were recorded in tank-based experiments to identify sound-producing species and the behaviours associated with their sounds as well as to quantitatively characterise and compare the sounds. A total of 34 sounds were associated with behaviours such as moving, feeding, mandible rubbing, swimming, species-specific behaviour and other unidentified behaviours. The sounds included single pulse and pulse train signals that were distributed... |

| Complete and transparent reporting of key elements of diagnostic accuracy studies for infectious diseases in cultured and wild aquatic animals benefits end-users of these tests, enabling the rational design of surveillance programs, the assessment of test results from clinical cases and comparisons of diagnostic test performance. Based on deficiencies in the Standards for Reporting of Diagnostic Accuracy (STARD) guidelines identified in a prior finfish study (Gardner et al. 2014), we adapted the Standards for Reporting of Animal Diagnostic Accuracy Studies—paratuberculosis (STRADAS-paraTB) checklist of 25 reporting items to increase their relevance to finfish, amphibians, molluscs, and crustaceans and provided examples and explanations for each item. The... |

| During its life cycle Carcinus maenas (Decapoda, Portunidae) goes through several phases of the moulting process (ecdysis) which allow it to grow despite having a rigid, non-living outer surface. As an individual approaches ecdysis, the exoskeletal calcium is solubilized (decalcification) from the shell and transferred through the integumentary epithelium to the blood, where much of it is transported to cells, tissues and organs of temporary storage where it is later mobilized for deposition into the new exoskeleton. We hypothesised that the decalcification process caused deterioration of the features and structures (e.g. tubercles and setae) characterizing the crab carapace, but that this can be reversed by moulting. We also tested whether wear and tear... |

| Interessante waarnemingen van epizoïsche kreeftachtigen op zeezoogdieren langs de Nederlandse kust (Cirripedia, Amphipoda) In de tweede helft van 2003 spoelden twee juveniele bultruggen Megaptera novaeangliae (Borowski, 1781) aan op de Nederlands kust, de eerste op 7 oktober op de Maasvlakte net ten zuiden van de ingang tot de haven van Rotterdam, de tweede op 20 december nabij Katwijk, Zuid Holland. Deze soort was nog niet eerder gemeld van de Nederlandse kust. Op de bultruggen werden vier soorten kreeftachtigen gevonden: Conchoderma auritum, Coronula diadema, C. reginae en Cyamus boopis. De laatste drie soorten zijn nieuw voor de Nederlandse fauna. Exemplaren van de parasieten zijn opgenomen in de collectie van het Nationaal Natuurhistorisch... |

| The effects of human trampling on the population parameters of the soldier crab Dotilla fenestrata at Praia da Costa do Sol, Maputo were studied in two areas subjected to two different levels of human disturbance: (1) a low disturbance area; and (2) a high disturbance area. Sampling was carried out 1 day before and 1 day after disturbance took place and crab abundance and biomass data were compared between the two periods at each area. No significant differences (P > 0.05) were found between abundance and biomass values before and after the disturbance. These results suggest that human trampling has an insignificant effect on D. fenestrata and that behavioral and habitat structure aspects might play more important roles on the population ecology of the... |

| Se analizaron 108 muestras recolectadas entre marzo y noviembre de 2009 provenientes de macrófitas y aguas abiertas de la costa oriental de la Ciénaga Grande de Santa Marta, adyacente a la desembocadura del río Sevilla, departamento del Magdalena. El mayor número de especies se registró en la zona de macrófitas. Este es el primer registro acerca de la existencia de cladóceros en esta región. Se encontró un total de 36 especies, de las cuales, ocho (Guernella raphaelis, Ilyocryptus plumosus, Moina eugeniae, Kurzia polyspina, K. media, Oxyruella longicaudis y O. tenuicaudis) son nuevos registros para Colombia. Además se hace una breve descripción de todas las especies y su distribución geográfica. |
