The Lamprey, also known as the Vampire Fish, is known to terrorize the other fish, such as the lake trout in the North America Great Lakes. According to Sea Grant, they are best known for there “toothed, funnel-like sucking mouth and rasping tongue which is used to bore into the flesh of other fishes to feed on their body fluids.” The government is now starting to notice the negative effect the Lampreys are having on the other fish in the North America Great Lakes and now want to control the fast growing population of the Lamprey. The Lampreys are aquatic vertebrates native to the Atlantic Ocean, use external fertilization and their populations are now being controlled by the agencies in the United States and Canada. A better understanding of the Lamprey, its habitats, life cycle, and control measures shows that the Lamprey needs to be controlled since it may cause damage to an ecosystem.
The Sea Lampreys (Petromyzon Marinus) are aquatic vertebrates that resemble eels, but unlike eels, they feed on large fish. They are also primitive jawless fish; they have a large sucking disk for a mouth and a well-developed sense of smell. Lampreys also do not contain any bones but only cartilage. Their bodies have smooth, scaleless skin, two dorsal fins, no lateral line, no vertebrates, and no paired fins. As larvae, a Lamprey is recorded to be about 6 inches long and an adult can be up to 18-24 inches in length. It is a dangerous fish because it is built to kill or prey on larger fish with poor defenses.
Research as shown that when a Lamprey has migrated into a different area it may negatively affect the ecosystem. Lampreys are found only in Mediterranean and North Atlantic, in the coastal seas off the North East USA, Nova Scotia, southern Greenland, the UK, Ireland and Scandinavia per to Marinebio. They are able to live in both salt and fresh waters, such as The Great Lakes, rivers, and steams. Lamprey can swim up canals that are
