The Trout population has been fluctuating. Some people say the Trout population has been changing because of pollution, but in this essay I will explain that the Sea Lamprey are causing the fluctuation. The Sea Lamprey are causing the trout population to change negatively because of population, the lamprey are an invasive species, and they are better adapted to their environment.
Firstly, the Sea Lamprey fluxuater the Trout population because the population is unstable. Graph A shows that the population became unstable when the Sea Lamprey came to the Great Lakes. When the Sea Lamprey first came, the Trout had 200,000 Trouts in it’s population. But when the Sea Lamprey had 300,000, the Trout had under 5,000. Finally, when the Trout had 150,000, the Sea Lamprey had under 50,000. This is an unstable population because there …show more content…
“The perch bends its body in the middle, but the sea lamprey moves its body back and forth more freely. A lake trout moves through the water just like the perch with half of its body going back and forth. This is why they are called half-body swimmers. The sea lamprey, on the other hand, uses its whole body to swim back and forth”. To explain, if Trout’s only use half their body to swim and Sea Lamprey uses all of it’s body, then the Sea Lamprey will swim faster. If the Sea Lamprey can swim faster than the Trout, then the Trout can’t run away from the Sea Lamprey. If they can’t swim away, then the Sea Lamprey will kill them. Next, “an average-sized female lake trout can lay 1000 to 15,000 eggs every other year. A female lamprey lays 60,000 to 100,000 eggs”. To continue, if a Sea Lamprey can lay 100 times more eggs that gives them more of a chance to survive compared to the Trout. If there are more Sea Lamprey trying to eat the Trout, then the Trout population will decrease. The Sea Lamprey are more adapted to water compared to the
