Neutral buoyancy, size, and thickness and ultrastructure of the chorion were studied
in eggs from populations of flatfish (Platichthys flesus and Limanda limanda) from
western Norway and three localities in the Baltic: Kiel, the Arkona basin and Tvärminne.
The observed differences in neutral buoyancy are probably caused by the differing
thickness of the chorion and are correlated with the salinity in the area. The
differences are thought to be the result of a long term selection process.
