The abundance and hatching success of Acartia bifilosa resting eggs in subtidal sediments of the Urdaibai estuary was analysed in the context of  a study on the spatial and temporal dynamics of this species. Two sediment  cores of 20 to 30 cm depth were obtained at two sites of the middle zone, where  the accumulation of mud and organic particles is favoured. Laboratory incubations  were performed to determine the hatching success of eggs and identify newborns.  Resting egg abundance was around 107 eggs m-2, and was higher at the site where  the A. bifilosa population maintains an optimal position in the water  column. The lower egg abundance in upper layers, as corresponds to winter,  was associated with the seasonal dynamics of planktonic populations. On average,  the hatching success was >50% at both sites. The lack of significant differences  in the hatching success according to sediment depth suggests that eggs remain  viable after being buried for a long-time in anoxic conditions. This enables  us to infer that the benthic egg bank of A. bifilosa in this estuary is a safe source  of recruits into the planktonic population, and plays a crucial role in recuperationand maintenance of the population
