Epic Eel Migration Mapped for the First Time

Maybe I'm wrong, but I don't think you are understanding the issue. These adult eels spend their lives in the rivers of Atlantic Canada. They come down the river once in their lives to breed thousands of miles away in the North Atlantic. The young eels somehow then make their way back to the rivers.

The high prices are for the "glass eels", the juvenile stage. They are caught with nets in the river as they return. This article is about the path taken by the adult eels from the river, to the ocean. Knowing the rough path they take in the ocean is unlikely to help anyone catch more eels.

If you want to catch the eels, you do it in the small river, rather than in the open ocean. Knowing more about their reproduction helps us understand and protect eels. Do you have reason to believe this is not the case?
