International audience Length–weight relationships for European silver eel (Anguilla anguilla) sub-populations in six countries (13 catchments) along the latitudinal gradient in the area of distribution in this study use three important sampling programs; these results concur with previous studies on European eel with the equation: W = 0.0010 L3.148 for the entire data set (sexes combined). Significant differences were observed among the13 catchments, possibly implying differences in body condition. Male and female LWRs varied significantly between and among catchments, suggesting that the capacity of silver eels to migrate and reproduce successfully varies according to the sites.
