IF he adds FHM to the pond the BG will not be able to control them to the point of the pond being over populated with FHM which will make the pond cloudy - murky. This low water transparency will I think result in slower growth of BG. I would only add FHM to an only BG pond, if the BG are were not going to be fed pellets.
A reproducing population of BG in 900 sq ft will over feed the invertebrate community and growth will not be anywhere near or equal to Condello's BG growth rate that Condello has in a controlled fish population pond that has abundant invertebrates as supplimental forage items.
Did bkunde ever answer my questions? How can we provide answers or advice if we don't have goals other than "Big Fat BG"? He needs to do more homework reading or someone else has to provide some homework reading assignments for him starting with info about HBG. I'm too busy to look all these old posts up for him. Cody, Conndello & Baird wrote "Behemoth Bluegills in Small Ponds" Parts I, II, III, (Pond Boss Mag, Mar-Apr, May-Jun, Jul-Aug 06) exactly for guys like bkunde. bkunde has a steep learning curve in front of him.
1. Where or how did you get your bgill for stocking? Describe the type of BG adults in this pond. A photo of several of the larger ones would be nice.
2. How many bgill would you like to get out of this pond per year?
3. What is acceptable harvest cleanable size of BG for you?
