Scientists at Wayne State University are researching how algae might help
disrupt reproduction of zebra and quagga mussels in the Great Lakes.
Kashian says preliminary study indicates algae produce chemicals that may
inhibit the invasive musselsí spawning. She and physiologist Jeffrey Ram are
trying to identify chemical cues the algae release and determine how they
could be used to develop a control strategy. It would be a cleaner
alternative to attacking the mussels with toxic chemicals.
eventually might help curb the destructive mussels, which have caused
widespread damage to the lakes since arriving in the 1980s in ballast tanks
of oceangoing ships. The filter feeders deprive fish of food, crowd out
native mussels and clog water intake pipes.
