Length Variation in Species and Hybrid Populations of Blue, Channel, and White Catfishes

Blue catfish (lctalurus furcatus) , channel catfish (I. punctatus) , white catfish (I. catus) , and their hybrids channel x blue, blue x channel, channel x white, and white x blue were produced and grown to an average total length of 150 mm and weight of 30 g in earthen ponds. Blue catfish (P < 0.0 I) and white catfish (P < 0.02) were more uniform in length than channel catfish. The channel x blue hybrid was more uniform in length than its reciprocal blue x channel hybrid and channel catfish (P <0.02). Uniformity of channel x white and white x blue hybrids was not different from...
