I have a 6 acre pond in the Cleveland area and am looking to increase growth rates in LMB. It is roughly about 15 years old and over the past few years I have taken out quite a few LMB but growth rates are slow and pretty insignificant. I was thinking about stocking adult BG and was looking at GSH. Will the GSH last and continue to reproduce each year? Or is that something I have to restock yearly? Generally the LMB are about 16" and around the 2# range give or take a little on both size and weight. I am looking for fish that look like the swallowed a baseball if you know what I mean. Any ideas or tips would be greatly appreciated.
