Do zebra mussels produce cyanobacteria?

Recent research found that chemicals produced by blue-green algae, also called cyanobacteria, are toxic to the larvae of invasive zebra and quagga mussels.

How do zebra mussels affect water quality?

In spite of their small size (often no bigger than a penny) zebra mussels cause far-reaching damage to water structures and native ecosystems. They also negatively impact aquatic ecosystems by harming native organisms. In huge numbers, they out-compete other filter feeders, starving them.

Can zebra mussels make you sick?

Do zebra mussels eat phytoplankton?

What do they eat? Phytoplankton: very small plants, like algae, that float in the water. Zebra mussels are filter feeders they take in water and remove what food they want.

What effect do zebra mussels have on the food web of the ecosystem of the Great Lakes?

What roles do native algae play in the Great Lakes ecosystem?

Why are algae important?

  • Algae produce oxygen as a waste product of photosynthesis.
  • Cyanobacteria are able to fix nitrogen from the atmosphere.
  • Algae help to ‘purify’ water by absorbing nutrients and heavy metals from streams and rivers.
  • Algae are the basis of most aquatic food webs.

The rate of reproduction and spread of zebra mussels make them efficient cleaners of Great Lakes water, but whether that’s a positive or negative thing depends on who you’re asking.

What are the negative effects of zebra mussels?

Zebra Mussels are especially harmful for native mussels, many of which are species at risk. They outcompete these species for food and will attach themselves to native mussels, suffocating them.
