Abstract: The subtropical convergence zone (STCZ) in the Sargasso Sea is an important spawning ground for the European and American eels, and the region is also strongly influenced by front and eddy formations and subsducsion of different water masses. This study was conducted to understand the physical and biological forcing that affect larval eels. European eel larvae showed pronounced diel vertical migration, which matched the distribution patterns of small hydrozoans, suggesting a predator-prey link between the two. Strong variations of the hydrographic conditions and distinct vertical distributions of other plankton groups were also observed within the upper 300 m, creating diverse niches for planktivorous fishes within the water column.
