Spatial and temporal distribution of decapod larvae in the subtropical waters of the Arvoredo archipelago, SC, Brazil
Provedor de dados: 76
Autores: Koettker,Andréa G.; Freire,Andrea S.
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...

Marine crustacean farming: present status and perspectives
Provedor de dados: 5
Autores: Laubier, Annie; Laubier, Lucien.
For centuries, several species of prawns and crabs have been raised from wild-caught juveniles in coastal brackish-water fish ponds in various countries of south east Asia. The Indonesian "tambaks" are well known examples of such traditional practices. In western countries, since the turn of the century, advances of marine biology and fast increase of marine fisheries enabled the development of large-scale production and release of larval stages of American and European lobsters in a fruitless attempt to restock natural populations. After the Second World War, the increasing demand for crustaceans in United States and Japan was satisfied by opening new prawn fisheries all over the world. A major breakthrough was achieved with the development of hatchery...

Organochlorinated contaminants in decapod crustaceans from the coasts of Brittany and Normandy (France)
Provedor de dados: 5
Autores: Bodin, Nathalie; Abarnou, Alain; Le Guellec, Anne-marie; Loizeau, Veronique; Philippon, Xavier.
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...

Integrative taxonomy revisits the ontogeny and trophic niches of   Rimicaris   vent shrimps
Provedor de dados: 5
Autores: Methou, Pierre; Michel, Loic; Segonzac, Michel; Cambon-bonavita, Marie-anne; Pradillon, Florence.
Among hydrothermal vent species, Rimicaris exoculata is one of the most emblematic, hosting abundant and diverse ectosymbioses that provide most of its nutrition. Rimicaris exoculata co-occurs in dense aggregates with the much less abundant Rimicaris chacei in many Mid-Atlantic Ridge vent fields. This second shrimp also houses ectosymbiotic microorganisms but has a mixotrophic diet. Recent observations have suggested potential misidentifications between these species at their juvenile stages, which could have led to misinterpretations of their early-life ecology. Here, we confirm erroneous identification of the earliest stages and propose a new set of morphological characters unambiguously identifying juveniles of each species. On the basis of this...

A white spot disease-like syndrome in the Pacific blue shrimp (Litopenaeus stylirostris) as a form of bacterial shell disease
Provedor de dados: 5
Autores: Goarant, Cyrille; Brizard, Raphael; Marteau, Anne-laure.
In May 1997, some white lesions evoking the white spot syndrome disease were observed in Litopenaeus stylirostris broodstock in New Caledonia. The occurrence of these lesions was neither associated with mortality, nor with histological evidence of white spot syndrome baculovirus (WSBV), The evidence suggests that these lesions result from a form of bacterial disease and are associated with an increased bacterial flora on the outer surface of the cuticle, as well as an increased incidence throughout the molt cycle. A microscopic observation of these lesions allows them to be differentiated from WSBV-associated lesions.

Chlordecone in the marine environment around the French West Indies: from measurement to pollution management decisions
Provedor de dados: 5
Autores: Bertrand, Jacques; Bodiguel, Xavier; Abarnou, Alain; Reynal, Lionel; Bocquene, Gilles.
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,...

New nemertean worms (Carcinonemertidae) on bythograeid crabs (Decapoda : Brachyura) from pacific hydrothermal vent sites
Provedor de dados: 5
Autores: Shields, J; Segonzac, Michel.
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...

Autores: Chim, Liet; Lemaire, Pierrette; Delaporte, Maryse; Le Moullac, Gilles; Galois, Robert; Martin, Jean-louis.
The prawn Penaeus stylirostris (Stimpson), when fed for 28 days with n-3 highly unsaturated fatty acid (HUFA)-enriched feed pellets, demonstrated an enhanced resistance to variations in environmental parameters (a decrease in temperature and salinity over a 4-day period from 28 degreesC to 17 degreesC and from 35 parts per thousand to 10 parts per thousand respectively) and an improvement in their immune defence potential, i.e. increased agglutination titre of plasma and increased respiratory burst of haemocytes.

Osmoregulation in larvae and juveniles of two recently separated Macrobrachium species: Expression patterns of ion transporter genes
Provedor de dados: 5
Autores: Boudour-boucheker, Nesrine; Boulo, Viviane; Charmantier-daures, Mireille; Anger, Klaus; Charmantier, Guy; Lorin-nebel, Catherine.
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...

Acoustic behaviours of large crustaceans in NE Atlantic coastal habitats
Provedor de dados: 5
Autores: Coquereau, Laura; Grall, Jacques; Clavier, Jacques; Jolivet, Aurelie; Chauvaud, Laurent.
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.

Factors influencing the deterioration of the carapace surface during the moult cycle of Carcinus maenas (Linnaeus, 1758)
Provedor de dados: 16
Autores: Greco, G.; Faimali, M.; Davenport, J.
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...

Exploitation et optimisation de la production des cystes du crustacé "Artemia tunisiana" (bowen et sterling, 1978) dans la saline de Sfax
Provedor de dados: 20
Autores: Aloui, N.; Amorri, M.
La saline de Sfax constitue le meilleur site pour l’exploitation et la production d’Artemia en Tunisie. La production de cystes est exploitée chaque année pour être utilisée dans l’alimentation des larves de poissons. Cette production est estimée à 30 kg de cystes poids sec. Toutefois, lors de nos campagnes de récolte, nous avons enregistré de grandes pertes de cystes occasionnées par les vents emportant les cystes qui seront mélangés avec le sable.    Afin de minimiser les pertes et optimiser la production naturelle de la saline, nous avons jugé utile, d’installer des barrages dans les coins des bassins à Artemia pour s’opposer à l’action du vent. Par ailleurs, nous avons fait un suivi mensuel de l’abondance des cystes récoltés et de quelques paramètres...

A Preliminary Investigation of the Effects of Human Physical Disturbance on the Ecology of the Soldier Crab Dotilla fenestrata (Crustacea, Ocypodidae) at Praia da Costa do Sol, Maputo
Provedor de dados: 20
Autores: Gonçalves, P.M.B.; Pereira, M.A.M.
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 &gt; 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...

Purificación de isoformas de proteasas tipo tripsina de crustáceos
Provedor de dados: 20
Autores: Rodríguez-Casariego, J.; Perdomo-Morales, R.; Perera, E.
Las tripsinas son las principales peptidasas digestivas de crustáceos. En los últimos años se han producido revisiones sobre  las tripsinas de invertebrados, así como de crustáceos, e incluso de las presentes en determinada especie de crustáceo. Sin  embargo, los aspectos relacionados con la purificación de estas enzimas (y sus isoformas) no se han abordado en estas  revisiones. En la presente revisión se exponen los procedimientos más empleados en la purificación de tripsinas de  crustáceos, las dificultades en la separación de isoformas, y se discuten las experiencias de los autores en la purificación de  isoformas de tripsina en la langosta espinosa Panulirus argus, las cuales pudieran ser de interés para los que se inicien en el  campo de la...

Brachyuran crustaceans from the bycatch of prawn fisheries at the mouth of the Amazon river
Provedor de dados: 36
Autores: Lima,Jô de Farias; Silva,Thibério Carvalho da; Silva,Luis Mauricio Abdon da; Garcia,Jamile da Silva.
The present paper is a pioneering study on the Brachyura bycatch associated with the artisan prawn fisheries at the mouth of the Amazon River. The study was conducted at four collection sites distributed along the mouth of the Amazon River between the months of January/2009 and January/2010. The animals were caught using handcrafted traps called "matapi", which are used by prawn fisherman in the region. Twenty matapis were used at each collection site. A total of 145 specimens were captured and six species were identified, all belonging to the Trichodactylidae family - Sylviocarcinus maldonadoensis, S. pictus, S. devillei, Valdivia serrata, Dilocarcinus septemdentatus and D. pagei. The most representative species, S. maldonadoensis, S. pictus and S....

Microanatomical characteristics of marginal ommatidia in three different size-classes of the semi-terrestrial isopod Ligia exotica (Crustacea; Isopoda)
Provedor de dados: 47
Autores: Keskinen,Essi; Takaku,Yasuharu; Meyer-Rochow,Benno; Hariyama,Takahiko.
The aims of this paper have been (a) to characterize marginal ommatidia from different eyeregions through a detailed description of their distinct ultrastructural features in three different size-classes ofL. exotica, and (b) to compare microanatomical characteristics of the marginal ommatidia with those of ommatidia of the same eye, but located further centrally. On the basis of transverse as well as longitudinal sections we conclude that new ommatidia are added from a crescentic dorso-anterio-ventral edge of the eye and that maturing ommatidia go through a sequence in which originally the nuclei of cone -, pigment-, and retinula cells are arranged in three separate layers. At the beginning of the microvillar development, the organization of the...

Provedor de dados: 52
Autores: Bernadochi,Ligia Coletti; Silvestri,Fausto; Turra,Alexander.
The composition and seasonal variation of brachyuran and anomuran species associated with mussel farms were evaluated at Praia da Cocanha, São Paulo between May 2007 and February 2008. Nine mussel ropes were sampled at random in each quarter, and 1,208 organisms were identified, comprising five families and 28 species. The most numerous species was the porcellanid Pachycheles laevidactylus (18.5%), followed by the xanthids Acantholobulus schmitti (16.6%), Hexapanopeus paulensis (11.3%), Panopeus americanus (10.2%), and Menippe nodifrons (8.4%). The exotic crab Charybdis hellerii was recorded throughout the study period. The ecological descriptors, except Pielou evenness index, varied significantly over the time. The highest abundance and diversity of the...

Electron microscopy of glial cells of the central nervous system in the crab Ucides cordatus
Provedor de dados: 56
Autores: Allodi,S.; Taffarel,M.
Invertebrate glial cells show a variety of morphologies depending on species and location. They have been classified according to relatively general morphological or functional criteria and also to their location. The present study was carried out to characterize the organization of glial cells and their processes in the zona fasciculata and in the protocerebral tract of the crab Ucides cordatus. We performed routine and cytochemical procedures for electron microscopy analysis. Semithin sections were observed at the light microscope. The Thiéry procedure indicated the presence of carbohydrates, particularly glycogen, in tissue and in cells. To better visualize the axonal ensheathment at the ultrastructural level, we employed a method to enhance the...
