Copepod parasites of fresh-water fishes and their economic ...
The irritation due to the presence of parasitic copepods may still further reduce
these movements and thus prevent infection by glochidia; but if this were the only
cause 10 copepods could hardly produce so large an effect. It would seem as if ...

In the laboratory, this transformation was facilitated by putting the microscopic
glochidia (-0.25 mm diameter) onto the gills or fins of host fish and maintaining
the fish in aquaria until the glochidia transformed into juvenile mussels. Once the
