The sea lamprey (Petromyzon marinus) is a parasitic lamprey native to the Northern Hemisphere. It is sometimes referred to as the "vampire fish". ... As the larvae ...
Oftentimes adult amphioxus and lamprey larvae are compared by anatomists due to their similarities. Similarities between adult amphioxus and lamprey larvae include a pharynx with pharyngeal slits, a notochord, a dorsal hollow nerve cord and a series of somites that extend anterior to the otic vesicle.

Each larva that grows into a juvenile sea lamprey will migrate into Lake Michigan and can kill 40 pounds of fish in its 12- to 18-month feeding period.
A lampricide is any chemical designed to target the larvae of lampreys in river systems before they develop into parasitic adults. One lampricide is used in the headwaters of Lake Champlain and the Great Lakes to control the sea lamprey (Petromyzon marinus), an invasive species to these lakes. [1]
Sea lamprey – fish that came through canals. Japanese stiltgrass – plant introduced in shipment packing material. Grass carp – fish introduced for aquaculture.
Sea lampreys devastated the fishing industry of the Great Lakes. Within 20 years of the lamprey entering the Great Lakes, the harvesting of lake trout was reduced by 98%. Control efforts included lampricides, physical barriers, pheromone alarms and baiting, and trapping. The control has been extremely successful in reducing sea lamprey ...
TFM (3-trifluoromethyl-4-nitrophenol) is a common piscicide, i.e., a fish poison used to combat parasitic and invasive species of fish. [1]The substance was discovered in 1958 when researching means to combat sea lampreys and it currently remains the primary lampricide (lamprey-killer) in the Great Lakes area.
The testing and figuring out the description of the larval and sea lamprey determines distribution, size structure, presence, and abundance in territories where they are located. [10] Great Lakes Fishery commission and the city of Grand Rapids white water will be receiving additional federal dollars to stop the invasive sea lamprey.
