BALLAST SLIME HATCHES AQUATIC INVADERS

Above is the connection to the glrc story on NPR.  I have a question.  I 
recall reading recently that it would be 'easy to remove living organisms' 
from ballast water by bubbling nitrogen gas through the hold before the 
ballast water is dumped.  My understanding is that aerobic organisms would 
be deprived of oxygen and would die.

Does anyone know more about this and the possibility of such a practice 
being instituted in the Great Lakes--late as it is?
