Based on the video context, it seems like the most effective bait for catching perch would be a gold robot spoon or a hair jig. The gold robot spoon is mentioned in the "How to Find and Catch Late Ice Jumbo Perch" video, where the angler recommends using it with maggots as bait. The hair jig is mentioned in the "9 Lures for Tough Winter Bass Fishing" video, where the angler suggests using it to drop down through a school of perch.
Perch are known to feed on smaller baitfish like minnows and perch themselves, so using baits that mimic their natural prey can be effective. The gold robot spoon and hair jig both have a slender profile that resembles small baitfish, making them attractive to perch.
It's important to note that the effectiveness of a bait can vary depending on factors such as water clarity, weather conditions, and the preferences of the fish. It's always a good idea to experiment with different baits and techniques to see what works best in your specific fishing situation.
