What problems do lamprey cause as an invasive species?
The sea lamprey invasion negatively impacted commercial fisheries—many fishing families went out of business. sea lampreys were so destructive that by some estimates, they killed more than 100 million pounds of Great Lakes fish each year—five times the commercial catch of lake trout in the upper Great Lakes!
Are there lamprey in Texas?

Fishery Impacts Other studies found that a single sea lamprey can kill 40 or more pounds of fish during its adult life. Fish that survive a sea lamprey attack expend more energy on healing than on producing eggs and mating, causing declines in fish populations.
What do you do if you see a sea lamprey?

Where are lampreys found in the US?
Sea lampreys are native to the Atlantic Ocean, Lake Ontario and the St. Lawrence River. They spread into the other Great Lakes via canals that bypassed natural barriers. They were confirmed in Lake Erie in 1921, Lake Michigan in 1936, Lake Huron in 1937, and Lake Superior in 1938.
Do lamprey bites hurt?
What eats a sea lamprey?
Sea Lamprey Predators and Prey In native habitation areas, lampreys’ biggest predators are larger fish, which can bite and attack them, including walleye and brown trout. In areas that the species has invaded, like the Great Lakes, it is often the apex predator, which is why its populations are so damaging.
