What I read was mostly in the "In-Fisherman" magazine. They just alluded to the two strains and did not really name them.

In the ponds where I have let the largest gills return to the water the size of the gills is going up. Not sure this is scientific proof, but it works for me.

Balance seems to come when 10 lbs of panfish are taken out for every pound of top line predator.
