![]() ZEBRA MUSSEL INFESTATION OF A NATIVE UNIONID
|
Small,
remarkable creatures ... far more sophisticated than one can imagine, and
perhaps the most threatening of all exotic species that have invaded North
American waters.
Their numbers are phenomenal...their spread is rapid...and in their wake is a trail of death & destruction. The message is clear - our rivers and lakes have been invaded, and the problem is critical. Perhaps of even greater concern is whether or not YOU are prepared for the scourge of zebra mussels. © Betty Wills |

This half-hour
documentary was recommended as an "excellent resource for cross-curriculum
units" in the December, '96 issue of BOOKLIST.
It also received a 3 Star Rating, Sept/Oct '96 issue of VIDEO LIBRARIAN,
and was recommended for public viewing.
Zebra mussels have spread from the Great Lakes south to New Orleans, LA., and have been spotted as far west as southern California. They are spreading into areas that were once thought impenetrable to the invasion. Their effect on the delicate balance of ecosystems is of major concern, particularly where there are increasing levels of toxic algae. This is a must see video for industrial and recreational water users, lake residents and boat owners. |

Zebra mussels
often settle in massive colonies, and can block raw water intakes, creating
havoc on raw water users. There is no magic bullet to stop their
spread.
|
Boaters inadvertently
transport zebra mussels to lakes and reservoirs, and should take
precautions before traveling to and from different systems in and out of
state.

Zebra mussels have wiped out entire populations of native unionids, (freshwater clams), in the open waters of western Lake Erie. Indications are that more unionids - some of which are endangered species - will be extirpated as zebra mussels spread across the country. There is an ongoing effort to save as many unionids as possible by removing them from the rivers, and keeping them in hatchery ponds in a safer, more controlled environment. |
