E. aquitanicus should have similar ecological characteristics as E. lucius in terms of habitat, behavior, and predation, because no difference were mentioned about ecological traits between Aquitanian and the other French pike populations, except an earlier spawning in February instead of March-April. Its size can exceed 1000 mm TL (Dégrave, pers. comm.) A pike of 1370 mm was mentioned by Laporte in Lake Cazeau, right in the heart of the distribution area of E. aquitanicus. However, we cannot exclude early stockings of E. lucius. When there is cohabitation between the two species, the Aquitanian pike is able to hybridize with the northern pike (present study)
