Lamprey Decline

OPB | March 31, 2011 8:30 p.m.

Populations of Eel-like lamprey have suddenly plummeted since the year 2000 in the Columbia Basin, surprising scientists. Lamprey numbers had increased for many years after the dams went in on the Columbia. Experts have built new ladders just for the lamprey to use to cross Bonneville Dam after learning they have great trouble with the conventional salmon ladders. Tribes, meanwhile, are restricting their harvest of this important cultural food.
