I am betting that the "Chicken Dinner" goes to Bocomo. The only bony materials in the pond are crawdads and other fish. The only artificial lures used in the pond have been small rooster-tails (besides hook and pieces of rubber worm) and I have not lost any yet.

I did catch a different gill that had a damaged tail fin that had healed. It was split down the middle all the way to the meat to give it an upper and lower fin.

The anal fin in the first pic does look a bit off and the protrusions do have color patterns consistent with the fin.

My first thoughts were parasites or hemorrhaging internals.

Fish on!,
