Osmotic and structural changes during early development of eggs and larvae of the cod, Gadus morhua L.
Newly extruded cod eggs have a similar osmoconcentration ( c. 400 mosmol kg ‐1 ) to maternal blood, maternal ovarian fluid and paternal semen. After extrusion, average egg osmolarities rise rapidly to about 520 mosmol kg ‐1 but this is entirely due to the cortical reaction resulting in the formation...
