| Summary: | No abstracts are to be cited without prior reference to the author.European eel (Anguilla anguilla) larvae have one of the longest larval migrations of the marine realm, swimming more than 6000 km from their spawning grounds in the Sargasso Sea to European continental shelves. The duration of this migration remains debated, being thought to be between seven months and three years long. This information is crucial, however, because it determines the period over which larvae are affected by environmental conditions and hence the subsequent recruitment success. We investigated the migration pathways and duration of eel larvae using three years of high-resolution (daily, 1/12°) velocity fields available from a MercatorOcéan model configuration without data assimilation. We specifically studied the impact of spatial and temporal resolutions on our estimates by applying various filters in time (from daily to 12-day averages) and space (from 1/12° to 1° gridcell aggregation) to the nominal model outputs. Larvae ... |
