TerryS. I can only comment on your question:

“How many bluegill will be sufficient for 200 bass?”
(I have a good friend who manages a handful of private ponds in the area and offered to supply me with 200 one to one and half-pound bass over the course of the spring so as to avoid costly stocking and waiting until fall (BG) and the following spring (Bass) for our fish supply.)

When we originally stocked our pond some four years ago, we stocked by the book with fingerling LMB and BG.
I got impatient and took up my friend’s neighborly gift of about ten adult LMB.
They promptly began feasting on the juvenile BG.

I asked Mr. Lusk for advise and if I recall correctly, he advised to stock seven (7) adult BG for each adult LMB – he may want to correct me on this.

If I am correct, you will need some 1400 adult hand size bluegill.

I would be wary of stocking 200 adult LMB until I had an adequate forage base established unless I was willing to stock adult bluegill.

Good luck on your pond,
George Glazener
