"They" tell me it is possible to stock female only but it is beyond my level of competency.
The GSF and catfish should not be a problem as long as you get your BG and any other forage fish well established early. In our neck of the woods GSF are a problem if they establish and spawn before the "good" forage base gets stocked. The big mouth GSF tend to eat all the tiny newly stocked fish. But once your BG get established you will find few GSF that make it past your large LMB. Same goes for BH. Long as you have large LMB they will not thrive and be few.
