Última Etude de la qualité microbiologique et chimique de la zone n° 62.10 « Baie de Canche : Hardelot / Le Touquet » groupe 3 ArchiMer Verin, Francoise; Caboche, Josselin; Lagache, Coralie; Lefebvre, Alain. A la demande de la Direction des Affaires Maritimes de Boulogne-sur-Mer, une étude sanitaire a été conduite sur la zone conchylicole « Baie de Canche : Hardelot/Le Touquet » en vue du classement de la zone de production pour le groupe 3 des coquillages bivalves non fouisseurs. Ce rapport présente un bilan des données disponibles sur la zone de production et les sources de contamination susceptibles d’impacter la zone de production. L’échantillonnage des coquillages moule a été réalisé sur le point de suivi « Dannes ». Les résultats des suivis microbiologique et chimique (dénombrement des Escherichia coli et teneur en métaux lourds Plomb, mercure et cadmium dans les coquillages) sont présentés et interprétés par rapport aux seuils réglementaires en vigueur....

This study aims to characterize the larval feeding strategy of the Downs sub-population of North Sea herring (Clupea harengus L.). Diet composition, vacuity rate and prey selectivity of larvae from 8 to 15 mm collected during the International Bottom Trawl Survey (IBTS) - MIK sampling from 2008 to 2013 were assessed by direct observation of their gut contents using Scanning Electron Microscopy (SEM). The high contribution of protists and small zooplanktonic prey observed in the gut contents proved the relevance of SEM to study the diet of first feeding larvae. The relatively low vacuity rate of 45% suggests that food may not be a limiting factor for Downs herring larvae in winter. These larvae appeared to be omnivorous and there was a clear shift in term...

Ano: 2016 URL: http://archimer.ifremer.fr/doc/00345/45606/45226.pdf Recent changes in ichthyoplanktonic assemblages of the eastern English Channel ArchiMer Di Pane, Julien; Koubbi, Philippe; Giraldo, Carolina; Lefebvre, Valerie; Caboche, Josselin; Marchal, Paul; Loots, Christophe. ish assemblages vary through time in both abundance and diversity, often due to changes in climate. The potential consequences of these changes on the larval phase need to be considered. In the Eastern English Channel, fish larvae of 30 taxa, from surveys conducted during spring in the nineties and in 2017 with bongo nets, were used to investigate seasonal and interannual changes in larval assemblages with different statistical tests and multivariate analyses (Outlying Mean Index, Principal Coordinate Analysis and variance partitioning). The major change observed was significant lower abundances in 2017 (in April and May) compared to the nineties. Most of the dominant taxa were two to three-fold less abundant in 2017 than the 1990s. We suggest that the... Tipo: Text Palavras-chave: Fish larvae; Temporal variations; Atlantic Multidecadal Oscillation; Outlying Mean Index; Variance partitioning; English Channel.
