Just a thought, and ez to check out. This spring I found a newly deceased walleye , 23" long , still very flexible and decent coloring.
Opened up stomach , back half of a plastic creature bait in stomach and stuck into exit to intestines. it was very skinny. I've had back 1/4 to 1/2 of plastics bit off my self on occasion, clients tell me of this happening to them , and no doubt that fishermen , not thinking of consequences , throwing badly damaged plastics in water , rather than taking home to garbage. Once in the currents of the BOW, they appear as food. Just a thought , if these fish are skinny , might double check stomachs , especially if a lot a plastics used in your BOW.
