| The presence of Mnemiopsis leidyi A. Agassiz, 1865 along the French coasts of the Eastern English Channel and the North Sea (EEC-NS) was established via morphological observation and molecular evidence. The earliest records were from surveys carried out in autumn 2005 in Le Havre harbour (Bay of Seine, EEC) and coincided with the historical introduction of the species in other Northern European waters. Since 2009, the species has also been frequently observed along the French coast of the North Sea. Results indicate M. leidyi has established a selfsustaining population in the Bay of Seine, which may act as a source population for northern European harbours via commercial shipping. |

| This study was aimed to develop an image analysis procedure using ZooScan an dits dedicated softwares for routine treatment of mesozooplankton samples from winter IBTS (International Bottom Trawl Survey) and use this procedure in order to identify, characterize and cartography mesozooplanctonic communities range in eastern English Channel and in the southern North Sea. The learning set obtained with the threatment of samples from winter 2008 allows a good autimatical recognition (above 85%) for main mésozooplancton taxa (i. e. copepoda, malacostraca, ichthyoplankton, appendicularia, chaetognatha…) For a deeper specific identification, a validation procedure by a taxonomic expert is needed to improve and correct identification. The spatial distribution of... |
