Agree with MD 100%
My advice is to stock 250 - 400 BG asap as it will take pressure off your YP and HBG as LMB forage.
Stock RES as bonus fish and to help prevent parasites - might have to go with Pumpkinseeds if you are too far North - a couple Winters will tell you what will work. We have some RES in Michigan [Coach B] and seem to be doing well.
Feeding will help your fishery in many ways, strongly encourgage at least hand feeding program if you live on site or feeder if absentee.
