Pond Boss Forums INTRO Questions & Observations planning a PB member Yellow Perch experiment

I guess a follow up question would be, should I be removing YP ribbons? I've got HBG, SMB, and HSB to control them. Plus don't YP cannibalize also? I run a feeder, but it's not a particularly reliable one. When it works (75% of the time) food is cleaned up in less than 30 seconds. I've been keeping a lot of YP to eat. We caught around a hundred this fall. They were a bit smaller than the ones we were catching in the spring. In the spring the larger fish were all females. In the fall there was no difference in size between males and females.
