A kind of strange sight, but not as strange as some have posted...

I'm going through my first year of experience with Tilapia in my ponds and wondering what I will find when the water temps hit the big 50 degree mark. Well, while riding on my tractor going around the dam in one "cove" recently I noticed a huge school of Tilapia suspended about a foot below the surface....just hanging out, kind of milling around, somewhat like mullet in the Gulf. There was easily well over one hundred of them of various sizes. They would spook at any detectable movement but soon return to hanging out. Kind of scared me as to what may be ahead when the temps plummet.
