What type of aquatic species could potentially disrupt local ecosystems and economies?

Aquatic invasive species (AIS) are organisms that are non-native to a specific ecosystem and whose introduction can cause significant harm to the environment, economy, or human health. These species can outcompete, displace, or even eradicate native species, leading to a reduction in biodiversity. AIS often reproduce quickly and thrive in new environments, sometimes turning into pests that disrupt local ecosystems and economic activities such as fishing, tourism, and water supply. Their presence can lead to changes in habitat structure and the food web, affecting both wildlife and human populations.

In contrast to AIS, native species are those that belong naturally to an ecosystem and have established roles within it, thus they typically do not disrupt the existing balance. Endangered species are those at risk of extinction, and while their survival is crucial for biodiversity, they are not inherently disruptive in the same way that invasive species are. Traditional species refer to organisms that are well-established in their habitats and often have been utilized by local communities for resources, and are typically not associated with negative impacts on ecosystems or economies.
