I personally wouldn't nuke a pond just because GSF got introduced. IMO SM/LMB prefer GSF over BG/RES due to their shape and softer body. Plus, GSF don't reproduce like BG. In 1/2 acre you can probably get them under control with a little patience and fishing pressure. Just toss everything that has neon blue/green gills out on the bank when you catch them. Use barbless hooks so you can easily release the BG/RES when they bite. This will also give you a good idea on the relative weights of your fish...get a small digital scale (I got my 5x7 inch scale online at Temu for under $10 with free shipping) Good luck culling them out!

Also GSF can get much larger than 3-4".
