The best way to catch big perch is using small lures or swimbaits. Anything that is about 2” (50mm) long and silver or bright coloured. A small 5 or 6 ft rod is perfect for the confined spaces, coupled with a medium sized real, loaded with 4 to 6 lb line. I always add a wire trace; the amount of times I have been after perch and seen a pike cruise out and engulf my bait or lure, make it worth while.

You are looking to imitate the roach fry (perch’s favorite snack), so cast into sheltered areas. A top spot for perch hang outs is always under over hanging trees. Natural food falls from the trees, the branches give cover from birds and the small bait fish hide out in the roots. Look out for schools of perch herding the bait fish and the fry breaking / scattering onto the surface.
Perch eat all year round but feed less in the Winter, however the clear waters help them spot your lure. Early morning Spring and Autumn are great times but the best is a warm Summers evening, just before dark.
