Declining Egg Production

We have a small zfish facility (3 breeding tanks) and have had our 
egg production slowly decline to zero in all tanks in the last few 
weeks.  The fish are breeding age and seem to be healthy (they 
have normal appetites and no unusual behavior). pH, NH3 and NO4 
are normal.  Nothing has changed recently in their maintenance 
protocol.  We do  have an ongoing problem with a whitish fungus 
that kills a large fraction of our eggs.  Does anyone have an idea on 
what might be causing this.  I've had nematodes suggested to me 
as a possible culprit.  Thanks very much.
