EAST LANSING, Mich-- A 12-year project at Michigan State University has set out to learn just how invasive species affect the Great Lakes, and its trout population.
It took multiple Graduate students years to see how Sea Lamprey- also known as Vampire Fish- affects the ecosystem.
The lamprey, which are an invasive species, use sharp teeth to latch onto fish and suck their blood.
At MSU, they've been studying the effects the lamprey has on trout in the Great Lakes. Student Tyler Firkus housed some trout at a lab in Wisconsin, and throughout the project, he let the lamprey attach to the fish for four days or less. Any longer than that, and they would die.
"We know that most of them will die when they are being attacked by a sea lamprey, but do the ones that survive still act like normal individuals in the population?" said Firkus.
