Comparisons of Hemoglobins and Hematocrits of Blue, Brown Bullhead, Channel, White, Crossbred, and Hybrid Catfishes
Hemoglobin patterns were identified by electrophoresis for channel catfish, Ictalurus punctatus; blue catfish, I. furcatus; white catfish, I. catus; brown bullhead, I. nebulosus; and (female x male) blue x channel, channel x blue, white x blue and channel x white hybrids. Hemoglobin patterns of each species were different with channel catfish having 11 bands; blue catfish, 8; white catfish, 5; and brown bullheads having 3 different patterns of 6, 10, and 11 bands. All hybrids except channel x white (10 bands) had 11 bands. The banding pattern exhibited by the hybrids was a combination of...
