Some more pictures of RES fingerlings I am raising in this forage pond to transfer to my main pond. RES is supposed to be the only sunfish in this pond. But I have trapped a fingerling GSF (likely came from main pond swimming up the overflow during high water event) so who knows.
Most look like pure RES but occasionally I get a few that look like they could have some GSF genes in them. Hard for me to tell for sure with a 2" fish. I know they are not GSF because I also have pictures of them and will put one below to show. As I start catching them again from the main pond as they get bigger (or catch some larger ones from this forage pond) maybe I can get a better idea. Funny thing is, I was wanting some GRES hybrids. I just did not think they would be coming from this pond!
Descriptions of what I think they are on the pictures. But I would not bet money on any of the ID's. Looking at the pictures the difference in the GSF (last picture is from a different pond) and the RES might not look that much different. But I can tell you, in person looking at them, there is a lot of difference. I can spot a GSF in a trap full of fingerlings easily. I can also tell the hybrids from the CNBG fingerlings easily. They are very apparent when side by side in person. The pictures do not do them justice. The differences just do not show up as well in the pictures as in real life. They likely would if I had a better camera.
I hardly ever get a FHM in the traps any more in this pond. Either the RES have done away with them or the GSH have out produced them. But I have a tremendous population of GSH, the other minnow in this pond. They are going gangbusters this year.
