Have found big brown trout are eaters of other fish primarily. Can remember where I grew up fly fishing back east on the Catskill rivers the old guy expert bait anglers. In the spring they would use a sown shiner or chubb and drift it down into holes and runs. Could not believe some of the big browns they pulled out that would not look at our little flies.
Another time we were coming back from Pepacton Reservoir in the Catskills which is a very deep NYC reservoir which has large browns which we drifted fish with sawbelly shiners. Well on our way home one time when we were passing where the Beaverkill and Delaware meet there is a large hole. It was July and water was very low. We stopped on the bridge and me and my two buddies saw about 15 -20 trout in the pool. A few large ones. We took some of the remaining sawbellys and threw them off the bridge into the pool never thinking these so called sophisticated Beaver kill browns would touch them.
Well a few big ones came right up and slaughtered those saw bellies. We left learning a lesson.
I am sure I will connect with a few next week.
Oh forgot, where I will be fishing for at least part of the time on the PM, is the trophy no kill section, this is where brown trout were first stocked in North America in 1882. Historic fishing area.
Lots of wild steelies will be there also
