Several interesting bits there. I thought the hybrids were sterile, but it appears that they are variably fertile. The article also states that the quality of the hybrid is fairly dependent on the parent strain of blue/cc, possibly making it harder to select a supplier. The article states that the hybrid grows faster than either parent, but does not comment on maximum size.
Should it be assumed that the maximum size is between that of a blue and a channel catfish, or that the hybrid can potentially get as big as that of a blue?
