Resumo: | The abundance of sole juveniles was estimated in October 1986 and 1987 for three nursery grounds which contribute to the stock of the Bay of Biscay (Bay of Vilaine : 332 km2, Pertuis Breton : 264 km2, Pertuis d'Antioche : 276 km2). Topography and sediments induce differences in sole distribution. The densities of juveniles are highest in both Pertuis, by x 6 to x 20 compared to the Vilaine. The interannual variation of the mean densities is opposite in the northern zone (x 0,66) and in both southern zone (x 2,13). The mean lengths of 0-group are different between the three sites ans between years. The contribution of a given nursery ground to the stock is not merely proportional to its surface and each of the nurseries may have its own dynamics. The final recruitment of the common stock would come from variable combinations of several contributing areas. Nevertheless, both Pertuis probably provide the main part of the recruitment
