Abstract
    To study a coastal nectobenthic fish nursery along the Pas-de-Calais in Eastern Channel, an appropriate sampling technique was developed by analysing the specific diversity and the multispecific structure of the samples obtained by trawling. In this paper I have examined the role of the trawling time to choose an average duration and the trawling direction compared to the tidal current to collect a representative fauna list of the fish community in the nursery. The optimized fishery sampling technique, based on the standard, was finalized at a speed for each trawling operation of about 1.5 knot during 15 minutes against the tidal current and parallel to the coast.
