    Résumé

    The local densities of Champsocephalus gunnari  observed in the 2013 survey are compared with those observed in 1994-1997. A significant increase in densities across 24 sites previously sampled was found. The comparison of the length distribution functions suggests that the stock depletion in the early 1990’s was due to recruitment collapse, probably a consequence of overfishing.
