Species | Development state | Trait | Primary Data | Secondary Data |
Dicentrarchus labrax | Egg | Egg size after water-hardening | A perivitelline space appears, 15 to 60 minutes post oviposition, whether or not the eggs are fertilized. The mean diameter of egg was 1.2 mm with 1.07 and 1.32 mm at minimum and maximum values [Egg diameters described in other places as 1.07-1.32 in Brittany, 1.02-1.296 in the Mediterranean coast, 1.386 for the North Sea] | 1.2 mm |
Dicentrarchus labrax | Egg | Egg Buoyancy | The fecund egg is pelagic, spherical and translucent | Pelagic |
Dicentrarchus labrax | Egg | Incubation time | [Mean of 115 ± 5 hours [At 13°C], 81 ± 3 hours [15°C] and 72 ± 2 [17°C]] | 115.0 days |
Dicentrarchus labrax | Egg | Temperature for incubation | Eggs collected at 9.5-16.5°C, mostly 13-15°C | 13.0 °C |
Dicentrarchus labrax | Egg | Degree-days for incubation | 62 [13°C], 50 [15°C] and 51 [17°C] | 62.0 °C * day |
