Too many SMB predators are likely limiting the YP recruitment. It is a common occurrence.
Agreed, and no mystery. You predicted this would likely occur way back when I stocked, particularly since you knew it would be unmanaged. You also noted that human-passive management of the SMB might be mitigated by adding the next top predator; Walleye. Every year I see numerous SMB fry and fingerlings, so annual recruitment is happening like clockwork. I also see YP egg strands every early spring. I cannot vouch for much of the RES activity, though I always see 5" -6" sunning over the sun-warmed concrete boat launch most of the year. So, Dr Perca, your crystal ball was and is accurate. Do you want to take the WE step in the near future?
