@fishlikemike: Destructive creatures! They have over 100 sharp teeth which are use to hold onto their hosts. Their preferred hosts are salmon and lake trout, however they also feed on walleye, northern pike, burbot, and lake sturgeon. Studies on the Great Lakes show a 40 to 60 percent mortality rate for fish attacked by sea lamprey. Other studies have found that a single sea lamprey can kill 40 or more pounds of fish during its life! A single lamprey can lay around 100,000 eggs per season! Even when fish survive the attacks, the fish populations will decline as the fish expend more energy on healing than on producing eggs and mating. • • • #fishing #lamprey #sealamprey #invasivespecies #invasive #wildlife #awareness #greatlakes #fishery #fish #salmon #flyfishing #wildlife #parasite
