Knobber - Removing as many tilapia as possible in September also removes nutrients for next years crop of algae. The planted plants should spread and grow better next year and beyond to help compete with the growth of excess algae.
Question - What type of sample did you have to send for the sediment fractionation testing? And what company did the testing?
I have yet to catch a Tilapia on hook and line, and usually the SMB or YP get to the bait first. The Tilapia gobble up any and all sizes of feed (including Endurance 22mm pellets), such that I stopped feeding for a while. Since I stopped pellet feeding, I noticed every speck of FA is just about gone.
My next attempt at bait will be to tie up a couple 5mm pellets in a mesh, similar to a spawn bag. If that fails, I heard that Tilapia will struggle at the surface in cooler Fall water temps and can be scooped up.
A bottom sample was taken from about 10 feet of water with an Ekman Dredge and sent to SePro for analysis.
