Species | Development state | Trait | Primary Data | Secondary Data |
Osmerus eperlanus | Egg | Oocyte diameter | Average 0.70-0.80, range 0.55-1.06 | 0.75 mm |
Osmerus eperlanus | Egg | Egg size after water-hardening | After extrusion into water, the egg immeadiatly swells, its diameter increases about 0.2 mm | 0.2 mm |
Osmerus eperlanus | Egg | Egg Buoyancy | Some of the eggs become detached and float with help of the outer coat, but seems to be only dead eggs | Pelagic |
