Thanks for the suggestions on the WEIGHT scales (and fish scales also BM).
My pond was built about 5 years ago. I don't have exact dates, but a few months after it was built, I added 250 bluegill and 50 catfish. A couple months after, I added 25 F1 bass. During a pretty dry time my pond level dropped really low and weeds were growing along the bank where I couldn't get to them to cut. Then one week we had thunderstorm after thunderstorm. Needless to say the water rose and when all the grass/weeds along the bank began decomposing I had a fish kill. (I didn't have an aerator at the time.) Being a rookie at this pond stuff I assumed it was a total fish kill, so I ordered the same type and numbers of fish as the original stocking. Looking back, its pretty evident that some of the original fish survived, and probably gorged themselves with fingerlings that I stocked.
I use a bug wacker during the summer and feed my ducks Mazuri waterfowl feed, which the fish LOVE. Its a race between the ducks and fish to eat as many pellets as quickly as possible.
Now if I could only get the bluegill to get some size....
