Pictures of three fish below. At first I thought the first two I caught were likely GSF, but the mouth did not look big enough. Caught the third one and it looked more hybrid but with the same mouth gape. So I finally decided they were all hybrids. Likely ones I caught out of my main pond and transfered to the old pond where I have native GSF. I really have trouble identifying hybrids until I catch a full GSF, then the GSF is obvious. I've only caught a few larger GSF out of this pond (6") but tons and tons of 4" ones.
Fish one 7" with 7/8" mouth gape Picture 1 Fish two 7" with 7/8" mouth gape pictures 2 and 3 Fish three 7 1/4" with 7/8" mouth gape. picture 4
All three fish together picture 5
Sorry about the dirt on the fish in the 5th picture, but the subjects were not being cooperative for the group photo. They all went back into the pond.
