I just built a pond that will be about 1 1/4 acres. It is a little over half full with the deepest. area about 7'. I am located north of Houston TX and my water is very muddy because of the clay bottom and banks. I just stocked 1000 bluegill 3"-5"; 100 bluegills 6"+: 20 lbs of flat head minnows and 20 lbs. of golden shiners. All came from Overton Hatchery. The bluegill were being fed pellets so I assumed they would eat pellets in my pond but I haven't seen one fish come to the pellets. Is that normal for winter time or do I have something to worry about?
