Species | Development state | Trait | Primary Data | Secondary Data |
Anguilla anguilla | Egg | Oocyte diameter | 1-1.4 [Unfertilized eggs] | 1.2 mm |
Anguilla anguilla | Egg | Egg Buoyancy | Newly fertilized eggs were at or near the surface | Pelagic |
Anguilla anguilla | Egg | Incubation time | 2-5 [Mass hatching after about 50-60h, range 47-120 [5 days at 20, but "the surviving embryos had a delayed hatch on day 5 after fertilisation"] | 3.5 days |
Anguilla anguilla | Egg | Temperature for incubation | 20 | 20.0 °C |
Anguilla anguilla | Egg | Degree-days for incubation | Certainly about 40-50 | 45.0 °C * day |
Anguilla anguilla | Female | Maximum GSI value | 31.8 in artificial conditions | 31.8 percent |
Anguilla anguilla | Female | Oogenesis duration | Under artificial conditions, maturation of females took 5-6 months | 5.5 months |
Anguilla anguilla | Spawning conditions | Spawning release | It seems that female eel undergoing artificial maturation function as batch spawners | Multiple |
