About Sea Lampreys
INSIDE A SEA LAMPREY'S MOUTH
Why are Sea Lampreys a problem?
Sea Lampreys are a problem because they are ruining the fishery and tourism by feeding on the game fish like lake trout, lake whitefish, chub, etc.
How much are Sea Lampreys costing Canada?
Sea Lampreys are native to
the Northern Atlantic Oceans.
How did the Sea Lampreys get to Canada?
Sea Lampreys invaded the Great Lakes in the early 20th century through shipping canals.
To keep Sea Lampreys under control would cost Canada,$8,000,000 per year. To protect the fishery is worth $4,000,000,000 to the great lakes region.
What is being done:
They have created a compound that will only be toxic to Sea Lampreys. the first compound was called T.F.M (trifluoromethyl). But unfortunately, Canadians aren't really doing that much.
You probably have been wondering what is being done to stop the Sea Lampreys. Well, here it is!
SEA LAMPREYS FEEDING ON FISH:
NOTICE THE SHARP SCALES?
DO U SEE THE SEA LAMPREY?
Their species are more than 300,000,000 years old (their older than the dinosaurs).
Their saliva contains a special enzyme that stops the preys blood from clotting.
How Sea Lampreys are effecting native species
Sea Lampreys are effecting our native species through elimination of the predators that Sea Lampreys are killing which also allows Alewife (another invasive species) to explode in population.
