Résumé :
|
Restoration of Atlantic salmon to the Penobscot river in Maine has met with limited success to date. Resarch in freshwater has emphasized problems created by dams. Fish passage research was initiated jointly by the Maine atlantic sea run salmon commission and the bangor hydro-electric company in 1987. This research was later broadened to examine environmental issues of flow and temperature.
