Research Paper On Sea Lamprey

Sea lamprey normally prey on a variety of native game fish but will also feed on any living thing it crosses. Some of these fish include: Lake trout, Brown trout, Lake sturgeon, Lake whitefish, Ciscoes, Burbot, Walleye, Catfish, Chinook, Coho salmon, Rainbow trout/steelhead. Sea lamprey use their jaw-less mouth to hook on to their prey, then their razor sharp tongue breaks the scales/outer layer of its prey, so it can feast on the blood and body fluids of the fish. Eighty-five percent of fish in the Great Lakes get fed on up to five times in its life. Although they do not want their prey to die, there is a 40-60% mortality rate for fish that get fed on. Even if the fish survives, fish populations still go down because it is expending energy
