Water Body Characteristics Impacting Zebra Mussels

When zebra mussels enter a water body, their chances of establishing a viable and successful population are dependent on the characteristics of the new habitat. In particular, a number of physiochemical and biological factors play key roles in this process.

 

Physiochemical Factors

Often the most critical physiochemical factors in determining successful zebra mussel establishment in a water body are:

Water Temperature

Calcium Level

pH Level

Dissolved Oxygen Level

Salinity Level

Water Velocity

Substrate Availability

 

Biological Factors

The relative abundance of certain biological factors can significantly impact zebra mussel population size, including:

Food

Natural Enemies

 

Water body Characteristics Altered by Zebra Mussels

As zebra mussel population densities increase, they, in turn, alter the physical and biological characteristics of the water body they inhabit. To learn more about these impacts, see the section titled Alteration of the Freshwater Ecosystem, An Overview.
