st - Fish contamination in a new pond is not the best way to start out, which is obvious. Can I assume the fry was big enough to recognize it to be a sunfish type shaped fish or a more slender minnow type? If sunfish type was probably (?) an offspring of the HBG. I am assuming you know the difference between a 4" hybrid bgill and a green sunfish. Hyb bgill contamination is probably a better situation than green sunfish contamination. Hyb bgill will result in fewer offspring that would need to be consumed / controlled by the perch and SMB which they could probably do fairly well. Greenies are another situation.

Get yourself a wire mesh minnow trap or two from WalMart or Meijers. Put them to work baited with bread catching the small "fry". If the traps are bright shinney wire mesh you may need to spray paint the mest a darker color so the fish more readily enter the trap. Fish tend to shy away from brightly colored traps.

I assume you call fingerlings that are 3/4" to 1" long, "fry". Based on the trapping results, this info will give you some indication how many of these small things are in your pond.

Depending on how pure of a perch/SMB combination you want will determine whether you will need a fish eradication or not. I am assuming the contamination came from the pumping/fill water? If that is the case, then I suspect your HBG are likely green sunfish. Do you have a closeup picture of the 4" HBG or additional fry that you can send me?
