Abstract: Curves of low genus on a surface carry important informations on thatsurface. We study the Fano surfaces of lines of cubic threefolds that contain12 or 30 elliptic curves. We determine their Picard number and compute a basisof the N\-eron-Severi group of the Fano surface of the Fermat cubic threefold.
