Zebra mussel guidance

Overview

The Pet Advocacy Network has released updated comprehensive guidance to pet businesses on how to correctly handle aquatic moss ball products and aquariums that could contain Zebra mussels (Dreissena polymorpha), an invasive species recently discovered in the United States.

Zebra mussels, which are fingernail-sized mollusks native to the Caspian Sea region of Asia, have been found within moss balls being sold and used in aquariums in stores in multiple states, including Oregon, Washington and Florida.

Zebra mussels are regarded as one of the most disruptive invasive species in North America. Adult mussels can stay alive for several days outside of water and commonly attach to boats, fishing equipment and aquarium plants. They clog water filtration pipelines, render beaches unusable, and damage boats, as well as negatively impact aquatic ecosystems by harming native organisms.

Based on the best available science, the guidelines have been updated to include information on how to properly dispose of moss ball products and decontaminate tanks specifically for suppliers, retailers and consumers/hobbyists. Pet businesses carrying aquatics products are asked to share the guidance with their suppliers and customers.
