Aquatic Animals

Invasive aquatic animals require a watery habitat, but do not necessarily have to live entirely in

water.

What are invasive aquatic animals?

These species are nonindigenous species that threaten the diversity or abundance of indegenous species, the ecological stability of infested waters, and any commercial, agricultural, aquacultural, or recreational activities dependent on such waters. They may even harm our health.

How do the spread?

Invasive aquatic animals can be spread in many ways including ships, boats, aquaculture, aquatic recreation and connected waterways. Through these and other means, aquatic invasive species have been introduced into South Africa.

Listed below are the invasive aquatic species according to Categories contemplated in the National Environmental Management Biodiversity Act (2004)Alien and Invasive species regulations 2014.
