<I>Shochu</I> distillery by-products (SDBP) is an underutilized liquid waste of a popular liquor, locally called "<I>shochu</I>", a fermentative product from sweet potato in Kagoshima, Japan. Growth performance of the common carp <I>Cyprinus carpio</I> L. fed with different levels of SDBP was examined. Test diets including 1%, 2%, 3% and 4% SDBP as dry weight in a commercial carp feed were formulated. The commercial feed without SDBP was used as the control. On addition of SDBP no marked change was observed in total protein contents of the diets. The weight gain, feed intake and specific growth rate of fish fed with SDBP diets for 40 days increased with increased SDBP. In these three parameters diets with higher levels of SDBP were significantly different (<I>P</I><0.05) from those with lesser ones. However, the food conversion ratio of fish reduced with increased SDBP. This suggests that SDBP might have nutritive and economic potentials to be used as a feedstuff for carp.
