New pond?? Or do you have fish in it right now? If so what kind? The pros will need to know all the information about your pond first before making recommendations.

How deep is your pond?
Do you have aeration?
Do you plan or are you feeding right now?
Is your water in good shape? Bloom? Do you fertilize?

Most places say at the very least 10BG for every 1LMB.

I've even seen 30-1 on some sites.

The experts will jump in soon I bet...but give them the low down on your pond and your end goals.

I put RES in with my BG.

You'll want a good forage base to start with so along with CNBG and RES, about 10#FHM to start with is good too. Most will say hold off on LMB till the next year or at least fall if you stock in spring...gives them a chance to spawn at least a couples times. This info is all from this great site!!
