The buoyancy of sprat (Sprattus sprattus) eggs and larvae in the Skagerrak area
Original version
This report is not to be cited without prior reference to the authorsAbstract
Buoyancy of sprat eggs and larvae was determined with a linear
density gradient. There were four experimental groups of eggs,
three caught at sea and one from spawning in the laboratory. The
neutral buoyancy of the sprat eggs ranged from 23.5-26.2
with the salinity range from 30.2-33.2 o/oo. No difference in
vertical distribution of eggs in different developmental stages
was shown.
The sprat larvae are expected to be at the same salinity range as
the eggs.
