What species is one of the biggest threats to the Great Lakes ecosystem?

Question

BlackTom AI · Accepted Answer

To tackle the question, we first consider the options and what each species represents in the context of the Great Lakes ecosystem.
Option 1: sea lamprey. This species is widely recognized as a major invasive threat to the Great Lakes. It attaches to native fish, feeding on their blood and body fluids, which has led to significant declines in several fish populations and disrupted ecological balance and commercial fisheries. Its impact is well-documented and central in discussions of Great Lakes invasive species.
Option 2: cutthroat trout. While native to some North American watersheds, cutthroat trout are not considered a primary threat to the Great Lakes ecosystem. They are typically viewed more as a sport or native fish and do not exhibit the aggressive parasitic or predatory functions associated with the sea lamprey.
Option 3: cod. Cod are not a native species to the Great Lakes and are not a major threat within that ecosystem. In fact, cod are more commonly associated with saltwater Atlantic fisheries and do not play a role as a destabilizing invasive species in the Great Lakes.
Option 4: wild salmon. Although salmon species exist in the Great Lakes, they are not recognized as a leading threat. The term “threat” here would imply a species causing ecological harm, but wild salmon are generally part of management and restoration discussions rather than being the principal invasive problem.
Option 5: jellyfish. Jellyfish can be a concern in some aquatic systems, but in the context of the Great Lakes, they are not identified as the dominant threat to the ecosystem. Their role is typically much less impactful compared to a well-known, history-rich invasive parasite like the sea lamprey.
Overall, the reasoning centers on identifying the species most infamous for invasive disruption in the Great Lakes, which aligns with sea lamprey as the principal threat among the listed options.
