Sea Lamprey are a voracious parasitic predator native to the Atlantic ocean. Like the Salmon and Steelhead it is an Anadromous species finding itself living/feeding during it’s adult life cycle in the lake or ocean and returning to the rivers and streams to procreate. The Lamprey has a suction cup like mouth lined with razor sharp teeth and a raspy tongue. The Lamprey aggressively attaches itself to a host where it carves away the outer scales and flesh to actively feed on blood and bodily fluids. An anti-coagulant exists in its saliva to aid in the process. As many as 1 in 7 hosts will die from Lamprey attacks. During one Lampreys life cycle it can consume and destroy as much as 40 lbs of fish. The entire lifecycle of a lamprey can range from 5 to 8 years with 12-20 months spent in the adult stage of the cycle in the lake feeding. They migrate and spawn in freshwater rivers where larvae hatch in the tens of thousands. This Larvae resides in the mud bottom of the rivers where it filter feeds for much of its existence before metamorphosing into voracious predators and head to the lake.
