Fish yields and ratios of naturally occurring stable carbon isotopes, 13C : 12C (reported as δ C) from 1-mu (670 m2) and 5-mu (3330 m2) ponds were measured. The ponds received daily inputs of green and animal manures as the sole organic inputs. Fish yields exceeding 40 kg/ha per day were attained in both the small and large ponds. δ C data indicated a strong contribution of the fresh fluid pig manure to growth of the two filter-feeding species, silver and bighead carp. Two grass-eating species, grass carp and Wuchang fish (Megalobrama amblyscephola), had significantly different δ C values, indicating partially separate food sources for each of these two species. © 1985.
