May last up to five years. Oh and by the way, they can kill up to 40. Sea lamprey marking on alternate hosts (e.g., chinook salmon) would be proportional to sea lamprey abundance and inversely related to the abundance of lake trout. The parasitic adult sea lamprey feeds on blood and tissue of large fishes, using the plates in their oral disk to grasp the prey and then rasp a hole, through which fluids and tissues are sucked (pearce
