Matches: baitfish generic.
When
When to use it
Strip streamers during low-light periods — dawn, dusk, and overcast days. Big brown trout are most aggressive in autumn.
Where
Where to fish it
Cover deep runs, undercut banks, and the back of pools. Swing or strip across structure where large trout ambush baitfish.
How
How to present it
Cast quartering downstream, let it swing on a tight line, then strip back with two-inch pulls. Vary cadence until you find the trigger.
