Severed intestine in channel catfish.
Six cases of severed intestines in farm-raised channel catfish were examined at fish disease diagnostic laboratories in Mississippi and Alabama. This condition has not been reported previously in fish. Affected fish had a 4-7-cm-long intestinal section (hyperemic where it was severed) attached to the stomach. The remainder of the intestine was completely missing in all six cases except for a 1-1.5-cm section of intestine prolapsed from the anus in fish from three of the cases. Ischemia, autodigestion following intussusception, or intestinal epithelium degradation are suggested as possible etiologies for this condition.
