Sorry for the delay in answering - been out of town. I got my Tilapia form Ken Hale at Boatcycle - he know what he is doing and definitely would have distributed both sexes. Today I saw quite a few large Tilapia at the surface and edges - the ones I stocked in April. I have few plants. I do have Chara (muskgrass) that they like to hang around but don;t know if they eat it or not. The FA I have seems to float to the top after growing on the bottom of the pond. My water is pretty clear - probably too clear. I have schools of bass fry everywhere - a bunch of 6-10 inch bass from this springs hatch and I would estimate 40 12-16 inch bass that I put in there to start the chain. I started with an 18 month headstart with Fatheads 500 bluegill fry and 30 7-9 inch bluegill breeding stock before I ever put bass in. Is it possible the bass are eating the Tilapia before they can get to the FA?
