Bass, perch, crappie, bluegill, trout. Same lake, different water, different depth, different month. Treating them as one fishery is how you blank.
Bass hunt structure. Perch peak after spawn. Crappie suspend — six inches is the whole game. Bluegill own the warm summer. Trout reset after every plant, and jumbos reset May.
The guide gives each fish its own playbook for exactly that reason. Pick the fish, then pick the rig.
