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 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
