Invasive Species: A Threat to Aquatic Ecosystems

Defining Invasive Species
Invasive species are non-native organisms that have been introduced into an ecosystem outside of their natural range and become established. They often lack natural predators or competitors in their new environment, giving them an unfair advantage. Invasive species can have devastating impacts on native ecosystems, including fish populations.

Examples of Invasive Fish Species
Two common examples of invasive fish species are the Chinese mitten crab and the common carp. The Chinese mitten crab, native to East Asia, has spread rapidly throughout Europe and North America, displacing native crayfish and damaging river banks. The common carp, originally introduced from Eurasia, is now found in many freshwater habitats around the world, outcompeting native fish for food and habitat.

Origins, Spread, and Management Challenges
Invasive fish species often originate from other parts of the globe. They may be accidentally introduced through ballast water, escaped from aquaculture facilities, or released by humans. Once established, these species spread quickly through waterways, disrupting ecosystems and affecting native fish populations. Controlling and managing invasive fish species is a complex challenge, as they are resilient and adaptable organisms. Methods include mechanical removal, chemical treatments, and habitat modification.
