Here is a close-up of a Great Blue Heron (Ardea herodias) who has just speared a fish of an unknown type. I was able to watch the whole process from the shoreline of the pond and took some shots.
I note that the photo here is not a super crisp, clear image. It is a crop of a shot that I had to tweak because of some problems getting the exposure right (reflected light off the water and shadows were both problem), but I like the fact that you can see both the heron’s and the fish’s faces.
In a posting on 24 July I showed a green heron swallowing a frog whole. I was not able to see how this blue heron consumed the fish because he carried it into a shaded area along the shoreline.

Great picture! Looks to be a small Largemouth Bass
Thanks for help with the identification of the fish, though that small Largemouth will not get any bigger.
