I'm located in Mississippi about 10 miles south of I-20. Not sure how that relates to your location within east TX. I've been thinking about Catfish vs Tilapia to add to my existing LMB, coppernose bg, redear pond. I'm starting to lean towards the tilapia for the very reason that they will die off each winter. So the affect that they have in your pond is of very much interest to me.
