Which species is an example of an aquatic nuisance you might encounter?

Zebra mussels are considered an aquatic nuisance because they are an invasive species that can cause significant ecological and economic harm once they establish a presence in a body of water. Originating from the Caspian and Black Sea regions, these small mollusks can rapidly reproduce and outcompete native species for food and habitat. They also have the ability to clog water intake pipes, damage boats and equipment, and disrupt local ecosystems by altering nutrient cycles.

In contrast, goldfish, while sometimes deemed a nuisance, are domesticated and don't have the same severe impact on ecosystems as zebra mussels. Trout are a native species and important for recreational fishing, contributing positively to the local biodiversity. Cattails, while they can dominate certain wetland areas, are also native plants that serve important ecological roles, such as providing habitat for wildlife and improving water quality. Thus, zebra mussels stand out as the clear example of an aquatic nuisance due to their invasive nature and the extensive problems they create.
