Trying to catch 9 previously angler jaw jerked LMB will TRULY TEST your angler ability. Do some serious intense finesse fishing before the LMB spawn. If you can manage to catch all 9 LMB you could be on the Bass Pro angler circuit. By all means return and let us know how the bass removal goes this spring. This will be educational. One remaining bass will be okay in the YP pond. I have one customer with all perch and he uses harvest and 1 LMB to help control numbers of YP. Works very good for him.

PS will eat some YP fry but NOT nearly as many of small YP as the GSF. Plus in my experience PS are not as prolific as GSF. GSF are truly a PEST for most pond fisheries. I would also remove small PS until you know you have good spawns of YP. Then use numerous PS to help control numbers of fry and small YP. Annual small fish trapping will be a primary management effort as long as you have GSF in the pond.
