https://srac.tamu.edu/fact-sheets/serve/252 Hybrids between the seven major species of North
American catfish (ictalurids) were first researched and
evaluated in 1966. Of these 42 different interspecific
catfish hybrids (crosses between two distinct species),
only one has characteristics that would favor commercial application compared to the prominently cultured
channel catfish (Ictalurus punctatus).
That hybrid is the
channel catfish female × blue catfish (I. furcatus) male
(denoted as the C×B hybrid). It is important to note that
mating the male channel catfish with the female blue
catfish does not produce a hybrid with the same superior
production characteristics as the C×B hybrid.
