I've seen YP performance like this...in my primary fishery actually.
That YP looks to be 70 WR - struggling for sure.

BG outcompeting YP for forage. If you want better YP growth should have reconsidered stocking plan to eliminate BG - but that's hindsight. Options as I see at this point:

1. Manage BG population through angling, trapping, seining. Reduce numbers as much as possible. You'll never remove enough to negatively impact fishery.

2. Source and stock pellet trained YP - they will perform much better than their natural forage dependent YP cousins.

3. Turbidity can affect YP feeding for sure - I've experienced this directly as well. Determine source of turbidity [sounds like BH might be the culprit] and address [trap/seine BH every day Spring-Fall].

I would combine all strategies if your goal is to raise YP with decent WR.
