From: Estimation of the spawning time of Japanese eels in the open ocean
Method used to estimate the spawning time of Japanese eels. Egg collection times (Supplementary Fig. S4)10,12, ascending speed of eggs (Fig. 2), swimming depth of silver eels (Supplementary Fig. S2)18, and Conductivity Temperature Depth profiler observed water temperatures are indicated by blue boxes. The assumed spawning time (overlap of the incubation and experienced temperatures, indicated by orange boxes) is considered to be the possible spawning time.
