Nice bluegill

I stocked my pond about 2 years ago with FHM, BG, and CC. I didn't fish for over a year, just feeding and enjoying the stress of watching my water level and rain forecasts. I assumed these were bluegill when I was first catching them but I have yet to catch anything that looks different aside from some now 4-6lb catfish that I'm pretty sure aren't BG. After pulling a few cats for the freezer and a bit of a fish kill I only have 1 left that I have seen in my little 1/4 acre pond and I'm trying to decide what to do to get rid of these GSF. Should I just toss some Bass and BG in there and see what happens or nuke it with Rotenone and start over. I do have some runoff that comes from a very forgotten poor condition pond upstream that I'm not sure of it's contents. If fry are floating down I may be sorta outa luck and LMB might be the best option.

edited to add pictures of larger gsf and bg

They sure look like GSF to me and nice looking at that. Do not underestimate the benefits of these fish (GSF). I am sure your CC are feeding on them. EDIT: I will leave it to the experts to say if these show any BG traits...I'm just not that good at firm ID's (yet).

Do you mean to say that you think you only have 1 CC left? If that is the case, adding more CC to the pond would be my first thought and larger than fingerlings...Maybe 20-40 10 inchers. CC will feed on the GSF. IIRC, GSF only breed once a year (or, at least, fewer times than BG) so they could make decent forage for CC. The GSF is a very tolerant fish and can live and reporduce in very neglected ponds. This upstream pond is likely the source. It sounds like your BG have vanished on you, so I would emprace the GSF add some more BG and CC. Make sure the BG are bigger than the GSF can eat and get larger cats that can start to feed on the small to medium sized GSF.

LM bass also love to eat those fish that are very close to green sunfish in your small pond.

I apologize, I didn't realize you could post pictures in other categories so I duplicated this thread in the fish management category. I have had very encouraging info from both regarding the GSF. I did some more fishing using a smaller hook and pulled up what I think is at least a hybrid if not full BG. If the fish truck comes through soon I'll restock and get more CC. There is a lot more to a successful pond then I would have ever imagined.

That 2nd fish with the yellow fins is a sterile hybrid bream/bluegill. I had quite a few of them when I re-did my pond until all were caught. They are often using when stocking a pond. Very little reproduction anyway.

I wondered why some had such bright yellow fins and others didn't and that makes sense. I need some sterile fish, my aerator must put them in the mood! haha

Hybrid bluegill are not sterile. First generation of hybrid bluegill is mostly male with a low percentage as females who do lay eggs fertilized by the males to produce some offspring. Each subsequent generation tends to produce more females. After several years usually lots of mixed genetic sunfish are produced each year.

Thanks for the information.
