About the International Conference on Aquatic Invasive Species

The International Conference on Aquatic Invasive Species (ICAIS) is the most comprehensive international forum to address new and emerging issues related to aquatic invasive species (AIS) in freshwater, marine and estuarine environments.

ICAIS provides an international platform for the presentation of research to advance global action to limit the introduction and spread of AIS worldwide and serves as a catalyst for international collaboration on research and management projects.

Through knowledge sharing and networking, ICAIS connects those involved in science and policy with practitioners and industry professionals on the front lines of AIS prevention and management.
