I am sure this subject has been beat to death previously but I am

a "fingerling" so I do not know where to go to read or study

this. I have a 4000+ ppm TDS 4 acre pond 60 miles south of

Wichita Falls. I know there are sources for Redfish somewhere

and that maybe there are methods to keep the water warm enough

in winter to avoid a kill. I would appreciate a lead.
