Comet assay comparison of different Corbicula fluminea (Mollusca) tissues for the detection of genotoxicity
Provedor de dados: Genetics and Molecular Biology
Autores: Rigonato,Janaina; Mantovani,Mário Sérgio; Jordão,Berenice Quinzani.
The comet assay was used to study the sensitivity of the widely distributed freshwater bivalve mollusk Corbicula fluminea to the DNA-damaging alkylating-agent methylmethane sulfonate (MMS). This study was undertaken to ascertain if C. fluminea is a good bioindicator of pollutants in aquatic environments and identify which C. fluminea tissue is most effective and practical for genotoxicity studies. The mollusks were exposed to 0.6, 1.2 or 2.4 X 10-4 M MMS for 40 min and their hemolymph, gill tissue and digestive gland tissue assessed for the level of DNA damage and the time needed for the tissues to recovery. Regression analysis showed a direct linear dose-response relationship between MMS concentration and the number of damaged cells for hemolymph and...

Provedor de dados: Genetics and Molecular Biology
Autores: Du,Zhi-Qiang; Jin,Yan-Hui.
Abstract Red swamp crayfish is an important model organism for research of the invertebrate innate immunity mechanism. Its excellent disease resistance against bacteria, fungi, and viruses is well-known. However, the antiviral mechanisms of crayfish remain unclear. In this study, we obtained high-quality sequence reads from normal and white spot syndrome virus (WSSV)-challenged crayfish gills. For group normal (GN), 39,390,280 high-quality clean reads were randomly assembled to produce 172,591 contigs; whereas, 34,011,488 high-quality clean reads were randomly assembled to produce 182,176 contigs for group WSSV-challenged (GW). After GO annotations analysis, a total of 35,539 (90.01%), 14,931 (37.82%), 28,221 (71.48%), 25,290 (64.05%), 15,595 (39.50%), and...

S'acclimater à des salinités et températures changeantes : un focus sur la branchie chez le loup européen Dicentrarchus labrax
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: 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...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lemonnier, Hugues; Royer, Florence; Caradec, Florian; Lopez, Etienne; Hubert, Clarisse; Rabiller, Emilie; Desclaux, Terence; Fernandez, Jean-michel; Andrieux-loyer, Francoise.
The gill is the organ by which many toxic metals are taken up by crustaceans. Iron is known to precipitate at its surface, a phenomenon recently observed in some tropical aquaculture ponds. The present study uses a field approach to understand better the environmental conditions and ecological processes involved in this deposit. Because shrimp are exposed to reduced products originating from organic waste accumulated in the sediment, spatial variation in pH, redox potential and concentrations of dissolved metals in pore water were investigated in these ponds. Total organic carbon, acid volatile sulfide and pyrite were also analyzed in the solid phase. Fe2+ in pore waters showed high spatial variability between ponds and within the same pond with...

Effets létaux et sublétaux à long terme d'un nonylphénol polyéthoxyle, le NP 5 sur la civelle
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: 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.

Recherche et élimination des facteurs inhibiteurs de croissance dans les élevages piscicoles en circuit fermé
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: 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...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: 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.

Autores: 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,...

Approche ecophysiologigue et ultrastructurale de l'osmoregulation chez les crustaces decapodes
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: 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.

Morphological Studies on the Gills of Puffer Fish (Lagocephalus sceleratus, Gmelin, 1789)
Provedor de dados: International Journal of Morphology
Autores: 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...

Provedor de dados: Neotropical Ichthyology
Autores: Oliveira,Bruno L.; Fernandes,Luiz F. Loureiro; Bianchini,Adalto; Chippari-Gomes,Adriana R.; Silva,Bruno F.; Brandão,Geisamanda P.; Gomes,Levy C.
Three experiments were designed to assess the accumulation and acute toxicity of copper (Cu) in juvenile fat snook Centropomusparallelus. The first experiment was performed to determine the 96-h lethal concentration (LC50) of Cu. The second experiment was designed to assess the effects of sublethal concentrations of Cu (0.47 and 0.94 mg/L), while the third one allowed us to test the recovery capacity of fish exposed to the sublethal concentrations Cu and kept in sea water without Cu addition. The LC50value for Cu was found to be 1.88 mg/L Cu. Fish exposed to the sublethal concentrations of Cu showed a significant accumulation of Cu in gills at 96 h respect to the control ones (0.43 µg/g Cu). No significant difference was observed in the accumulation of Cu...

Consideraciones sobre el crecimiento de la caballa (Scomber japonicus marplatensis)durante su primer año de vida
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: 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.

Mitochondria-rich cells changes induced by nitrite exposure in tambaqui (Colossoma macropomum Cuvier, 1818)
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: COSTA,OSCAR T.F. DA; RAMOS,CLEVERSON A.; DUNCAN,WALLICE P.; LAMEIRAS,JULIANA L.V.; FERNANDES,MARISA N.
ABSTRACT The gill mitochondria-rich cells of the juvenile Amazonian fish Colossoma macropomum were analyzed using light and scanning and transmission electron microscopy after 96 h exposure to 0.04 and 0.2 mM nitrite. Although the number of mitochondria-rich cells decreased significantly in the lamellar epithelium, no decrease was found in the interlamellar region of the gill filament. Nitrite exposure caused significant reduction on the apical surface area of individual mitochondria-rich cells (p &lt; 0.05), with a resulting reduction of the fractional area of these cells in both the lamellar and filament epithelium. Swelling of endoplasmic reticulum cisternae, nuclear envelope and mitochondria were the main changes found in the mitochondria-rich cells....

Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Georgieva,Elenka; Stoyanova,Stela; Velcheva,Iliana; Yancheva,Vesela.
This work aimed to study the effect of new neonicotinoid thiamethoxam on the histological structure of common carp (Cyprinus carpio, L.) gills. Three experimental groups of fish were treated with 6.6, 10 and 20 mg/l thiamethoxam in laboratory conditions. Results showed different histological changes in the gill epithelium, which included lamellar lifting, edema, proliferation of the glandular cells and epithelium, covering the gill filament, fusion and degenerative alterations. The blood circulatory system showed mainly vasodilatation. All thiamethoxam concentrations activated compensatory-adaptive mechanisms, which caused pathological changes in the gills. Moreover, there was a tendency towards the enhancement of the gill histological changes, whose...

Epithelial gill cells in the armored catfish, Hypostomus cf. plecostomus (Loricariidae)
Provedor de dados: Brazilian Journal of Biology
Autores: FERNANDES,M. N.; PERNA-MARTINS,S. A.
Epithelial gill cell morphology and distribution were investigated in the armored catfish, Hypostomus cf. plecostomus, which lives in soft ion-poor Brazilian freshwaters. Pavement cells are the most abundant type of cell on both filament and lamellar epithelia and there are a great number of mucous and chloride cells between them. Mucous cells are almost covered by adjacent pavement cells and have large packed granules showing electrondense differences. No mucous cells were found on the lamellar epithelium. Chloride cell were distributed throughout both epithelia and usually have large apical surface facing the external medium and may exhibit short and sparsely distributed microvilli. The presence of chloride cells on the lamellar epithelium may be an...
