Method of Transportation
They (sea lamprey) are still mostly found in the great lakes and brought over here by fishermen.
They are found in the St. Mary, and st. johns river.
They prey on important fish species, such as lake trout living off the blood. Also Sea Lampreys can kill to 40 pounds of fish a day. They attack the fish with the structure of the mouth then dig their teeth into their flesh for grip.
We should be able to kill them and then if possible make them extinct.
