Abstract
Turbot eggs, following activation, are relatively impermeable to tritiated water. Thirty degree-days after fertilisation, the permeability of turbot eggs increased with age. In general permeability increased with temperature, Q10 ranging from 2.15 to 3.84, and decreased with age. Acute change in salinity had no significant effect on permeability. The effect of alterations in external calcium had no effect on permeability in 15.5 degree-day eggs, but at 31 degree-days permeability appeared to increase as external calcium concentration fell.
