Snrub - next one you catch measure the mouth gape of horizontal and vertical axis. One thing I am exploring is using the mouth gape to distinguish GSF from other species and hybrids. The GSF of any specific body length should have the largest gape horizontal and vertical compared to pure BG, RES, and the hybrids. I have a pretty good list of mouth measurements for GSF.
