Analysis of the genetic structure of European eel (Anguilla anguilla) using microsatellite DNA and mtDNA markers
The spawning population of European eel (Anguilla anguilla L.) has been considered panmictic on the basis of genetic markers and morphometric studies. This hypothesis was tested by screening glass eel from five locations (Ireland, Italy, Morocco, Sweden and U.K.), belonging to two cohorts at the cyt...

The spawning population of European eel (Anguilla anguilla L.) has been considered panmictic on the basis of genetic markers and morphometric studies.
