Estuaries are important areas highly vulnerable to anthropogenic pollutions. Therefore, the assessment of estuarine water quality is a major ecological issue. In this study, we sampled juveniles of the European flounder in the “pristine” Canche estuary, and caged them in Canche and in two polluted sites of the Seine estuary, Rouen and Fosse Nord. After one month, the metal and organic pollutants in these sites were assessed, and we evaluated several phenotypic indicators (condition index, RNA/DNA ratios and genotoxicity), and extracted the proteins in fish livers for analysis using a shotgun proteomics approach. The results showed strong modifications in the fish caged in both sites of the Seine estuary, as compared to those caged in Canche. In particular,...

Catálogo Fauna Ictica asociada a la pesquería chilena de orange roughy (Hoplotesthus atlanticus)
Provedor de dados: 20
Autores: Tascheri, R.; Pequeño, G.
El orange roughy (Hoplostesthus atlanticus, Collet 1889), es una especie de aguas profundas de un alto valor comercial, que presenta una amplia distribucion geografica en los oceanos atlantico, Indico y Paci­fico. Los estudios de edad de Orange roughy muestra que es una especie de crecimiento lento que alcanzari­a sobre los 100 años de edad. La actividad pesquera en torno a este recurso, de reciente desarrollo en Chile, ha permitido la recolección de muestras de la fauna ictica asociada a esta pesqueríi­a que reviste especial especial interés cienti­fico, en áreas como la zoologi­a y biogeografi­a , estudios que unidos a datos geologicos pueden contribuir a responder importantes interrogantes como la distribucion de orange roughy en areas geograficas tan...

Stress in pacu exposed to ammonia in water
Provedor de dados: 96
Autores: Abreu,Janessa Sampaio de; Esteves,Fábio Resende; Urbinati,Elisabeth Criscuolo.
The present study evaluated stress indicators in pacu exposed to ammonia in water under the following conditions: without NH4Cl (0.00 g/L); with 0.0078 g NH4Cl/L; and with 0.078 g NH4Cl/L (pH 8.3 and 27 ºC). After the salt dilution the water flow was interrupted and reestablished in 24 hours. Sampling occurred prior to the addition of NH4Cl (control) and after 12, 24 and 48 hours. Glycaemia increased only in fish with the highest salt concentration when compared with group control, regardless of time, and at 24 hours, regardless of treatment. Plasma ammonia, highest in fish exposed to the highest NH4Cl concentration, decreased progressively up to 48 hours. Plasma chloride only decreased in fish not exposed to salt when compared with control and osmolality...
