Which of the following is a common aquatic nuisance species?

• A. Giant Salvinia
• B. Catfish
• C. Rainbow Trout
• D. Crappie

Answer: (A)

Giant Salvinia is indeed recognized as a common aquatic nuisance species. It is an aggressive floating fern that can rapidly cover water surfaces, blocking sunlight and depleting oxygen levels in the water. This disrupts aquatic ecosystems and can harm native plants and animals. The growth of Giant Salvinia can lead to issues such as reduced water quality and limited recreational opportunities for boaters and fishermen, making it a significant environmental concern. In contrast, species like catfish, rainbow trout, and crappie are typically sought after for recreational fishing and are considered part of healthy aquatic ecosystems when present in appropriate numbers. They do not exhibit the same invasive and disruptive characteristics as Giant Salvinia that can lead to ecological problems. Understanding the impact of aquatic nuisance species like Giant Salvinia is crucial for maintaining waterway health and biodiversity.
