To support strategies ofspatial fishery management, we developed a high-resolution biophysical model to describe scallopdispersal in English Channel and to quantify the relative roles of local hydrodynamic processes,temperature dependent planktonic larval duration (PLD) and active swimming behaviour (SB) on theconnectivity between 18 stocks identified from different sources (e.g. ICES data, VMS data). TheEnglish Channel currents and temperature were simulated for 10 years (2000-2010) with the MARS-3D code and then used by the Lagrangian module of MARS-3D to model the larval dispersalpathways.Results were analysed in terms of larval distribution at settlement, the larval retention rate and theself-recruitment rate, two metrics commonly reported in studies on local populations’ persistence, andconnectivity among stocks. Furthermore, the connectivity among areas within a stock was assessed indetail on the examples of the two main stocks in the English Channel (i.e. Bay of Saint Brieuc and Bayof Seine) for which the distribution of scallops is well documented from annual stock surveys.
