Greg, my pond is about 24-26 feet deep. i have been told to tell the corps it is only 24.5 feet deep if they ask though!! do you think the threadfin would make it here? i noticed what you said about the gizzard shad, and i am not too keen on that. greg, what is the scoop on tilapia. it seems to be avoided a lot on this site, but the name keeps popping up and i'm curious. thanks.
