How do sea lamprey affect humans?
Before sea lamprey control, sea lamprey predation on valuable fish stocks was so high it became a key factor in the collapse of the Great Lakes ecosystem and economy that it supported; tens of thousands of jobs were lost, property values were diminished, and a way of life was forever changed for millions of people.
What eats a sea lamprey?

Why do lampreys attach to fish?
To feed, they latch onto fish, bore into them, and start sucking down blood and body fluids, often killing their prey in the process. A single lamprey can kill up to 40 pounds of fish; and hordes of them threaten the Great Lakes fishing economy, which is valued at roughly $7 billion a year.
Do lampreys only live in fresh water?
Sea lamprey, like many salmon, are “diadromous”. They spend the early stages of their life in streams and rivers. The middle stage of their life is spent in the saltwater of the ocean or in a large freshwater lake.
