Genetic analysis of the American eel helps explain its decline

The numbers of American eels in freshwater areas have been decreasing rapidly but scientists have been puzzled as to why the fish can’t recolonize. Now, a new look at eel genetics finds that there are differences between eels that feed in freshwater and eels that feed in brackish environments that were previously thought to be genetically interchangeable.
