Canadian Geographic - - WILDLIFE -

Alex Gon­za­lez, a fish bi­ol­o­gist with the U.S. Fish and Wildlife Ser­vice, tells CBC of plans to con­trol a grow­ing sea lam­prey prob­lem in Lake Su­pe­rior, where the blood-suck­ing in­va­sive par­a­sites are killing trout and other fish. Gon­za­lez said the ser­vice would like to re­duce by half the es­ti­mated 40,000 to 60,000 lam­preys liv­ing in the lake.
