Another study of hybrids including back crosses.

Includes GSFmale x RES fm as well as the opposite cross.
1979
Use of hybrids in ponds and impoundments

It appears from this study at least, that RES female x GSF male is the preferred cross from a growth standpoint. The start of this thread was a study of GSF female x RES male.

Contains info on back crossing also.
