For carnivorous species, the primary food source is blood. Some commonly parasitized prey includes herring , trout , mackerel , salmon , sharks, and marine mammals. They latch on to their prey using their suction-cup like mouth and scrape away the skin.
Especially with smaller fish species, this can eventually injure or kill the host. Some species have been accidentally introduced as an invasive species in the North American Great Lakes. They feed heavily on native fish species, causing damage and population decline. Some species of parasitized fish, like the lake trout , have high commercial value. This means that not only are the lampreys damaging the native populations, but also the local economy.
There are a number of initiatives to reduce the invasive lamprey population, including the introduction of sterilized males, and implementation of pheromones. No, lampreys would not make good pets because they must feed off of live fish and would be difficult to care for. The non-carnivorous species do not have long lifespans. Some invasive species are illegal to own as pets because of the danger they pose to natural habitats. Different species of lampreys have very different needs.
The larval stage must move from freshwater to saltwater in anadromous species, which makes them difficult to breed. The freshwater species do not live for long periods once they metamorphose.
Carnivorous species live in saltwater conditions, but must move to freshwater in order to breed. Much like sea lamprey found off the Atlantic coast, sea lamprey living within the Great Lakes have a similar reproductive cycle. The adult sea lamprey living in the Great Lakes migrate to streams to spawn. Once these adults find a suitable spot for spawning, they build their nests and fertilization takes place. Once the eggs hatch and the ammocoetes emerge, the ammocoetes float down stream and burrow into the bottom or bank of the stream.
After the ammocoetes reach maturity, they migrate back to the Great Lakes to begin the free swimming stage of their life cycle. For more information about the life cycle of a sea lamprey, visit the New York State Department of Environmental Conservation website.
