I kept the brown and it's stomach was very full of isopods as they usually are in the winter.
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 1/2" long 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 (midge larvae) 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 for me to see how the trout eat isopods.
