The CNBG, for the most part, have been in the ponds for a long time. They come in various sizes all the way up to and over 10 inches. This spring I made a pilgramage to Tyler Fish Farm to get some of Bob's CNBG genetics in my ponds. He hand selected CNBG from Florida many years ago and has some terrific genetics.
One of the limitations of this study is lack of a prefect control group, i.e a CNBG pond identical in every respect to the TGG pond. To combat that weakness, I requested and received "control group" data from Bill Cody. Interestingly, that control data is pretty uniform across the South.
The TGG through the winter, exceeded that baseline data, doubling it in fact, and now that the growing season is really underway, appear to be exceeding that baseline even further.
