Sure thing!  I'd be glad to help.  Two-pound bluegill are a realistic goal in this area with proper management.

Hey Iteago, it's great to hear from you.  Man, that stinks that those jerks are sabotaging your pond!  I used to joke that if I ever owned a pond I would put up a hurricane fence of razorwire around it and let a panther loose on the property and only feed him once a month so he stayed hungry - maybe you need a panther!

 

That's awesome that you're coming home - I'll say some prayers that God keeps you safe between now and April.  I know you have to be excited.  We will definitely get your pond in shape, get some hawg bluegill growing in there. 

 

I do notice a couple things from the photos you posted.  The water looks pretty shallow on the side closest to where you're standing for the upper photo, the one that shows the bench and chair in the water.  You might think about getting that dredged out when you expand the pond.  Very shallow water makes it harder for the bass to control the bluegill, and it also makes the pond more prone to excessive weedgrowth.

 

The other thing I notice is that the water is pretty murky.  Do you still have 850 catfish in there?  That would be the one good thing that might have come from the trespassers - I'm hoping they caught out a bunch of those catfish, because that's about 800 too many catfish for a pond that size if you want to grow big bluegill.  I would suggest letting a friend set a trotline or banklines around the pond to try to catch out as many as possible of those catfish.  They will be a big problem in managing for bluegill, because the most important thing you can do to grow giant bluegill is to feed them, and those catfish will eat all of the food so the bluegill can't get any - they'll actually knock the bluegill out of the way with their tails while eating.  I would almost recommend rotenoning the pond and starting over just to get those catfish out of there, but you may not want to do that.  But you will definitely need to work hard at getting them out of there.  I've done it before, most recently in a four-acre pond that was stocked with 1200 catfish; you just have to be aggressive in fishing them out.  The catfish are probably why your water is muddy - they're rooting up the bottom looking for food.

 

Definitely send me more photos if you have them.  Also, do you have a topo map of your land so I could get an idea of what the watershed is? 

 

As far as keeping out trespassers, something a lot of people do these days is to install a couple game cameras pointed at the pond (hidden up a tree so they're not easily seen/tampered with).  Then you put up a sign that says the premises is being electronically monitored and that trespassers will be prosecuted to the full extent of the law.   One other thought I have is to put up an electric fence just around the pond, say twenty yards or so from the edge of the pond.  Putting it just around the pond would cost a lot less than putting it around all of your land.
