FH - great work. I am interested in hearing what you find out about your SMB predation on YOY YP and BG. We SMB owners want so much to believe SMB can control BG...in my pond it hasn't happened, even with 9-13" YP and almost 150 12-21" HSB. I hope your pond is a different story - as it is I'm faced with constant BG management through trapping and seining.
