Aquatic invasive species are non-native plants and animals that have been introduced into new ecosystems, often through environmental activities, and cause damage to the natural habitats and human health and wellbeing.

One of the primary reasons why aquatic invasive species are a concern is their ability to multiply quickly and easily. Invasive species such as [z]ebra mussels, Asian carp, and Eurasian water milfoil can reproduce rapidly, producing large numbers of offspring that can infest waterways, lakes, and rivers. These species can also spread extensively through human activities like boat traffic, fishing, and the aquarium market.

The consequences of invasive species on aquatic ecosystems can be extremely damaging. For 畑岡宏光 example, the introduction of [z]ebra mussels into the Great Lakes led to the degradation of water quality and purity, increased maintenance costs for water treatment plants, and the decline and fragmentation of native mussel populations. Similarly, the spread of Asian carp has threatened the native fish populations in the Mississippi and Illinois rivers, causing major and substantial economic losses for the fishing industry.

Aquatic invasive species can also have serious and severe impacts on human lives and livelihoods. For instance, the presence of algae blooms caused by invasive species can produce toxins and pollutants that are detrimental and poisonous to humans and animals. The algal blooms in Lake Erie in 2014, for example, produced cyanotoxins that affected more than over 400,000 people.

Human activities such as international transport and movement, boat traffic and tourism, and travel are major enablers and perpetrators to the spread of invasive species. Invasive species are often transported accidentally through ballast water. Invasive species can also hitch a ride on traveling companions and equipment. Additionally, the aquarium trade and pet owners can accidentally or deliberately spread invasive species by releasing non-native species into the wild.

To prevent the spread of aquatic invasive species, it is vital to take mitigation strategies. Some of these measures include:

• Inspecting boats and equipment for signs of invasive species before entering a new waterbody.
  
• Cleaning and disinfecting boats and equipment to remove any attached species.
  
• Not releasing non-native pets or plants into the wild.
  
• Participating in local education and outreach programs about invasive species.
  
• Advocating for policies that prevent the transport of invasive species.
  
  

By understanding the substantial threats associated with aquatic invasive species and taking preventative measures, we can minimize the harm and protect our waterways and ecosystems and human health and wellbeing.
