You guys can generate a lot of discussion from a relatively poor and distant photo of that fish. The pectoral fin is obscuring the opercule flap and the photo does not have a good "shot" of the head features which are important in a fairly accurate identification. I'm not sticking my neck out until I see a better photo.
I have a local pond owner that has some big pure GS in his pond. I verified that fact last year. He said some are 10" long. He caught several last weekend that were 9 1/4" and ate those. Next time he gets a 9.5" or larger he will call me so I can get a photo and body measurements.
