Mysterious Eels' Mating Migration Tracked


Rare European eels from the Mediterranean to Scandinavia make an epic journey when it's time to mate. They leave rivers and brackish habitats, swimming hundreds of miles across the Atlantic to the Sargasso Sea, an open ocean region that is warmer, saltier, bluer and clearer than the surrounding waters.

This trek had remained a mystery to science since no eggs or adult eels have ever been caught in the Sargasso Sea. But researchers recently attached satellite tags to about 600 eels from different places in Europe and were finally able to map the route of the spawning fish.

"We could track the satellite tags as far away as the Azores. This suggests that the eels take a different route to the Sargasso Sea than previously thought. It seems as if they’re saving energy by hitching a ride on the Azores Current," researcher Kim Aarestrup, of the Technical University of Denmark, told youris.com.
