MY DILEMMA

I had rockbass in my pond with my goldfish and they did a wonderful job of keeping my fish population under control.  Last winter 2013-14 was so severe that I lost a lot of goldfish and all my rock bass.  With no predators to eat the babies they lived and now I have way, way too many baby goldfish.  Last spring I purchased minnows that were crappies and walleye.  I was hoping they would eat the babies.  If they ate any, they didn't consume many.  My pond is 15' X 30' and too large to be able to catch the minnows easily.

MY PLAN

This fall I plan to net my favorite big goldfish and keep them in two large tubs (150 gal.) each, in the basement.  Then I will let the pond freez over in hopes of killing off a vast number of goldfish.  The downside of this plan is that it will likely kill off the remaining big goldfish, and leave the babies that need less oxygen.  I have one tub and am currently shopping for a second.  I have tried netting the baby goldfish, but they are way too fast to net easily.
