Abstract:

The polyculture of common carp and channel catfish was investigated during June to November, 1972, at the Fisheries Research Unit of the Auburn University Agriculture Experiment Station, Auburn, Alabama in order to see if the presence of carp would result in increased production of channel catfish and would improve water quality. Seven earthen ponds 0.1 acre in size were stocked with 400 fingerling channel catfish and either 0, 2, 3, or 5 fingerling carp each. Fish were fed six days per week. Water samples were taken weekly from 5:00-6:00 A.M. and 2:00-3:00 P.M. Net production of catfish tended to be higher in the ponds which contained carp. Except in one pond which had no carp the net production of channel catfish was higher in those ponds which contained carp, however, the difference was not significant. Of the water quality variables studied, dissolved oxygen, pH, ammonia nitrogen and turbidity, the presence or absence of carp seemed to affect only turbidity. Although there were differences in the levels of a particular variable, those differences did not seem to be related to the presence or absence of carp, but were the result of seasonal effects and differences in pond ecologies. Although possibly the result of chance variation, the presence of carp seemed to enhance the production channel catfish. Certainly the relationship was positive enough to justify further experimentation using more replications.
