Nice catch! And very good photographic evidence of the need to remove a lot of those fish.

Most of those bass are skinny and would likely give a Wr (relative weight, a measure of body weight to length, a good number would be 95 to 115 or more) of from around 65 to 75, or not quite starving to death.

However, notice how much better shape the crappie seem to be than the bass, an indication that they are finding a food supply the bass can't use or are better at utilizing what is available. Many times this is where the food items available are small, like insects or shrimp, and involve a lot of energy on the part of the bass, less so for the crappie, to capture.

When you see a bass pond where the bass are having to feed on dragonflies, not just where they jump at me now and again for fun, they are starving. The energy it takes to catch the dragonfly by jumping out of the water is far greater than the energy taken in even if it is caught.

Note that the larger the bass, the better it looks, an indication that the larger fish are finding big prey not available to the smaller ones. I'd measure thoe and draw my line there, below comes out, above goes back. If you can tell sex, remove mostly males, putting back most of the females.

The sunfish in the photo is a nice bluegill, looks similar to a redear, which would be almost white in color with a bright red gill plate spot.

I've fished many places like yours. Those bass don't really look stunted to me. I bet you don't catch many small crappie?
You've just got too many bass but I bet you've got plenty of forage. I'll say there are some really big bass in there but are really hard to catch because the smaller bass are eating the lures first.
You have a good problem. I would keep everything under 17 inches and keep culling. If its an older pond you may need some new bass genetics in there to get things growing again.
Short story. I had a friend with pond that produced like yours does now. He wanted a bass factory so with advice from a fishery guy he drew down the lake, killed and started over. He no longer had crappie and big bluegills.
Like was restocked with florida bass and coppernose and threadfin shad and tos of fathead minnows. 10 years later he has caught a couple of fish over 11 lbs. but he is not getting the recruitment of bass from 5 to 8 lbs and he back to getting stunted fish. He sure misses those crappie and big bream.

Fish fry coming soon! Nice Catch.
