Abstract
    Specimens and nests of Pomatoschistus pictus adriaticus have been caught for the first time along the French Mediterranean shore (Gulf of Lions). Six types of nests are found on sandy-gravelly bottom at 10 m depth and 25·3 to 27·5 g l−1 salinity, using in 84·7% of cases, a valve of Cardium edule (3·3 < weight g < 40·6; 507 < surface mm2 < 2490). Nest size, egg patch, surface area and nesting fecundity are positively correlated. Nesting fecundity varies between 669 and 4690 eggs. For a similar egg diameter, the egg height is less than that of P. minutus which spawns on the same bottom and localities. Larval length at hatching varies from 1·70 to 2·67 mm.
