The buoyancy of sprat (Sprattus sprattus) eggs and larvae in the Skagerrak area
(ICES CM Documents;1985/L:6, Working paper, 1985)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 ... -
