Biology
Zebra mussels are filter feeders, and they are capable of filtering about one litre of
water per day while feeding primarily on algae. They were transported from
Europe as stowaways in the ballast water of transoceanic ships and pose
significant social, economic & ecological concerns for the Great Lakes and other
inland North American waters.
Effect On Food Chain
The zebra mussel disrupts natures food chain. They remove nearly all particle

faced with the challenge of trying to find a
way to eliminate zebra mussels while at the same time leaving native species
unharmed. Methods such as chlorination, chemical treatment, ozone, heat,
ultraviolet radiation, electrical shock, anti-fouling paints, and sonic vibrations are
being tested right now. The use of biological agents, including toxic
micro-organisms, parasites, and spawning inhibitors is also being investigated.
Although some treatments have proven very effective, completely eliminating
zebra mussels is not likely.
