Approche ecophysiologigue et ultrastructurale de l'osmoregulation chez les crustaces decapodes ArchiMer
Pequeux, A; Lignon, J.
This paper deals mostly with recent physiological data on ion transport across the gill tissue and an attempt is made to correlate them with blood osmoregulation and ecological distribution in euryhaline decapods. A particular attention is paid to the gills of the fully euryhaline Chinese crab Eriocheir sinensis . Supporting this ecophysiological approach, there is an important ultrastructural analysis of the gill epithelium under various salinity conditions. The possible part played by the cuticle in ions movements is also considered.

Consideraciones sobre el crecimiento de la caballa (Scomber japonicus marplatensis)durante su primer año de vida OceanDocs
Sánchez, R.P..
Through the analysis of the morphological changes ocurring in the process of growth, it was possible to identify three stages (primary juvenile: 25-75 mm; secondary juvenile: 76-160 mm; and juvenile preadult: 161-250 mm)during the first year of the species life. Regression equations for the different relations studied: body weight/body lenght, body surface/body lenght, body surface/body weight, and metabolic rate/body lenght, have been calculated for each stage. The variation of the number of gill rakers, mean distance between adjacent rakers and mean values of gill rakers lenght in reference to body growth was studied, and the relation between filtering area and body length was established.

Differential distribution of V-type H+-ATPase and Na+/K+-ATPase in the branchial chamber of the palaemonid shrimp Macrobrachium amazonicum ArchiMer
Boudour-boucheker, Nesrine; Boulo, Viviane; Charmantier-daures, Mireille; Grousset, Evelyse; Anger, Klaus; Charmantier, Guy; Lorin-nebel, Catherine.
V-H+-ATPase and Na+/K+-ATPase were localized in the gills and branchiostegites of M. amazonicum and the effects of salinity on the branchial chamber ultrastructure and on the localization of transporters were investigated. Gills present septal and pillar cells. In freshwater (FW), the apical surface of pillar cells is amplified by extensive evaginations associated with mitochondria. V-H+-ATPase immunofluorescence was localized in the membranes of the apical evaginations and in clustered subapical areas of pillar cells, suggesting labeling of intracellular vesicle membranes. Na+/K+-ATPase labeling was restricted to the septal cells. No difference in immunostaining was recorded for both proteins according to salinity (FW vs. 25 PSU). In the branchiostegite,...

Diseases of cultured prawns in Australia ArchiMer
Lester, R; Paynter, J.
Plebejus baculovirus and other MBV-related viruses have been found in Penaeus plebejus, P. monodon and P. merguiensis . They appear highly pathogenic in certain situations currently undefined. We have found Hepatopancreatic Parvo-like Virus (< hpv) in wild P. esculentus and P. merguiensis but not yet in cultured prawns. The amphophilic intranuclear inclusion bodies we find in P. esculentus do not appear to have a viral cause.

Effects of biodegradable detergents in the accumulation of lipofuscin (age pigment) in gill and liver of two neotropical fish species. Repositório Alice
PEREIRA, B. F.; ALVES, A. L.; SENHORINI, J. A.; ROCHA, R. de C. G. de A.; PITOL, D. L.; CAETANO, F. H..
Currently there is a growing concern, in both population and governments, to identify the effects of substances commonly disposed of into rivers and lakes, on aquatic fauna and flora. Thus the objective of the present study was to verify effects of biodegradable detergents and water from an urban lake on gills and liver of two neotropical fish species of great economic importance, Astyanax altiparanae and Prochilodus lineatus. In order to do so, lipofuscin, also called the ageing pigment, was used as bioindicator. After one and five months of experiment both tissues accumulated this pigment. These data are discussed from physiological points of view, related with lipid peroxidation and mitochondrial damage.

Effets létaux et sublétaux à long terme d'un nonylphénol polyéthoxyle, le NP 5 sur la civelle ArchiMer
Bocquene, Gilles; Miossec, Laurence.
Studying different concentrations, we have determined LT 50 of a non-ionic surfactant on elver eel: the polyoxyethylated nonylphenol NP 5. Then we studied sorne sublethal effects on fish behaviour and histological effects on gills, during 21 days. We demonstrated primary effects on gills structure and we believe in an impairing of the central nervous system.

Etude quantitative et qualitative des métallothioneines chez la daurade "Sparus aurata" exposée aux métaux lourds OceanDocs
Ameur, S.; Ghedira, J.; Guerbej, H.; Jebali, J.; Bouraoui, J.; Boussetta, H..
Dans l’environnement marin, les éléments traces peuvent s’accumuler dans les organismes à des concentrations supérieures à celles présentes dans l’eau. L’étude de la distribution tissulaire des métaux traces au niveau des organismes qui y sont exposés, constitue un aspect très important pour la compréhension de leur devenir. En outre, le suivi de la réponse biologique spécifique de ces organismes sentinelles aux xénobiotiques complète et consolide l’analyse chimique. Ce travail vise à étudier la distribution tissulaire des métaux traces et des métallothionéines (MTs) chez la daurade «Sparus aurata » traitée par un métal essentiel (le cuivre) et un métal non essentiel (le cadmium) à une concentration de 500µg /Kg de poids frais pendant 48 heures....

Incidence de la salinite sur les equilibres de distribution hydrique et ioniques et sur le metabolisme respiratoire dans le muscle blanc, le muscle rouge et la branchie chez le muge Chelon labrosus ArchiMer
Gallis, J; Piquemal, S; Lambert, J; Sergent, P; Rousseau, V.
Oxygen consumption, water, K super(+) and Na super(+) contents were measured in white muscle, red muscle and gill epithelium in the mullet Chelon labrosus) in relation with the duration of fresh water or sea water (1500mOsm) adaptation. The unit respiratory activities in gill and red muscle where respectively 5 and 3 timesmore elevated than in white muscle. The pericellular K super(+)/Na super(+) ratio of the 3 tissues decreased with the fresh water adaptation duration. In the gill, the intracellular K super(+)/Na super(+) ratio was stable while the parameter decreased strongly in the white muscle. The results are discussed in relation to energetic cost of homocellular regulation and homoepithelial regulation.

Morphological Studies on the Gills of Puffer Fish (Lagocephalus sceleratus, Gmelin, 1789) International Journal of Morphology
Abumandour,Mohamed M. A; Gewaily,Mahmoud S.
In the present study, we focused on the morphology of L. sceleratus gills using gross anatomy, scanning electron microscopy as well as light microscopy. Results of this study revealed that the gill openings appeared as simple slits anterior to the pectoral fin without distinct opercular cover. The gill system consisted of three pairs of gill arches carrying two rows of gill rakers on its concave border and gill filaments on its convex border. SEM showed that all surfaces of the gill arch were characterized by the presence of the longitudinal ridges with many taste buds in addition to many spines around the rakers. Histologically, the gill arch was composed of curved bar of hyaline cartilage with slightly elevated area corresponding to the sites of gill...

This work is the first study on parasitic fauna of Curimata cyprinoides Linnaeus, 1766 (Curimatidae) and the host-parasite relationship. The total of 154,740 parasites such as Ichthyophthirius multifiliis (Ciliophora), trophozoite of Spironucleus sp. (Hexamitidae), Urocleidoides sp. (Monogenoidea), Digenea gen. sp. and Polymorphus sp. (Polymorphidae) were collected. The component community showed low diversity (HB = 0.004 ± 0.020) and parasite species richness (1.4 ± 0.6). However, I. multifiliis and Urocleidoides sp. were prevalent and with higher intensity on the host population and also aggregated the distribution pattern. The occurrence of these ectoparasites in C. cyprinoides may be a consequence of its alimentary diet. Positive correlation between...

Primeiro registro da ocorrência de protozoários em tamoatá Hoplosternum littorale no Brasil. Repositório Alice
PINHEIRO, D. A.; TAVARES-DIAS, M.; DIAS, M. K. R.; SANTOS, E. F.; MARINHO, R. das G. B..
Este estudo relata a primeira ocorrência de protozoários nas brânquias de tamoatá Hoplosternum littorale (Hancock 1828) (Siluriformes: Callichthyidae) no Brasil. Dos espécimes examinados, no período de julho a agosto de 2011, 95,3% estavam com as brânquias parasitadas por protozoários Ichthyophthirius multifiliis (Ciliophora) e/ou Piscinoodinium pillulare (Dinoflagellida), sendo que os maiores índices de infecção foram causados por I. multifiliis. A abundância desses parasitos não foi influenciada pelo tamanho dos peixes e não afetou o fator relativo de condição (Kn) dos hospedeiros. Este é o primeiro relato de índices epidemiológicos para H. littorale na Amazônia brasileira.

Recherche et élimination des facteurs inhibiteurs de croissance dans les élevages piscicoles en circuit fermé ArchiMer
Leonard, Noemie.
Recirculation of the water of fish rearing systems requires a biological treatment based on the nitrifying activity of autotrophic bacteria. In parallel heterotrophic bacterial populations utilise the organic substrate, produced by the fish, to grow. Opposite to the autotrophic populations, the heterotrophic bacteria (1) have a quick growth and (2) might contain fish pathogenic strains. The main aim was to characterise the heterotrophic bacteria populations ?.nd to understand (1) which parameters do control the dynamics of their populations and (2) their influence on the quality of the recirculating water. In a rearing system, the heterotrophic bacterial populations are stable in number and in genus, for a given operating mode. The bacteria are either...

S'acclimater à des salinités et températures changeantes : un focus sur la branchie chez le loup européen Dicentrarchus labrax ArchiMer
Masroor, Waliullah.
The European sea bass Dicentrarchus labrax undertakes seasonal migrations to estuaries and lagoons that are characterized by fluctuations in environmental conditions. It is unclear to what extent salinity acclimation mechanisms are affected at temperatures higher than in the sea, as usually encountered in transitional waters in spring and summer. In this study, juvenile sea bass were pre-acclimated to seawater (SW) at 18 °C (temperate) or 24 °C (warm) for two weeks and then transferred to either fresh water (FW) or SW at the considered temperatures. We have shown that sea bass are able to efficiently maintain blood osmolality at 24 °C at both salinities. However, temperature increase induced significant changes regarding several physiological traits...

Surface Ultrastructure of the Gills of Odontesthes bonariensis (Valenciennes, 1835)(Teleostei: Atheriniformes) from a Temperate Shallow Lake International Journal of Morphology
Tano de la Hoz,María Florencia; Longo,María Victoria; Escalante,Alicia Haydée; Díaz,Alcira Ofelia.
We studied the gill epithelium of juveniles of Odontesthes bonariensis using scanning electron microscopy with a particular interest in the relationship between cell morphology and the different functional aspects of gills. The specimens used were collected in Laguna de los Padres, Buenos Aires Province, Argentina. The gill filaments or primary lamellae are arranged in two rows along the convex outer face of the gill arch forming the anterior and posterior hemibranchiae. On its concave inner face, each arch supports two rows of gill rakers forming the pharyngeal region wall. The primary lamellae are lined by a stratified epithelium made up of polygonal cells with well-defined outlines and cell membrane microfolds. Several mucous and chloride cells were...
