Isopods as I know them are bottom crawling critters about 10-13mm long. How do you suppose these good sized trout are capturing these relatively small critters from the bottom areas?? I have watched YP nose down suck up items with sediment off the bottom keeping the good parts and exhausting the sediment.
those YP are eating soft pellets that have settled onto the bottom. YP reportedly do the same feeding method capturing blood worms and burrowing mayfly larvae.
Do you think the trout are feeding the same way or are they individually picking up the isopods one by one? It would be very interesting fo me to see how the trout eat isopods.

Here is a picture of one from one of my trout's stomaches from a couple of years ago. Each trout I keep usually has a completely full stomach of dozens of these. I'm not sure how they are eating them. The bottom of the pond is all sediment from decomposing curly leaf pondweed that dies off in the summer. Maybe this video I took a few years ago of the trout also eating soft pellets on the bottom through the ice will help. They did not seem effective at eating those.
