MMMMMMMMMMMMM band-aid

I have on numerous occasions found stuff in steelhead bellies. From dyed shrimp, eggs, grass hoppers, and once even a rubber worm.
There is a debate, whether the digestive system is active, or the steelhead are just swallowing as a reflex. My theory is that the digestive system is partially active, and that the steelhead can milk their food like eggs, or juice shrimp etc. Evolutionarily speaking, I don't think it would be a good design if steelhead ran up the rivers voraciously feeding. I think that mostly they don't feed, but minimally some do. Just my two cents.

I do think that in post spawned steelhead, you will also find a higher instance of feeding.
