The suspended solids in Fuqiaohe Reservoir, Hubei Province were seasonally sampled and analyzed from 1998 to 1999.The mean amount of total suspended solids (TSS) in dry weight was 9.99l mg/L, among which 93.22% was contributed by organicdetritus and 6.78% by plankton. The no-ash weight in suspended solids was 3.45mg/L,among which 85.540 was contributed byorganic detritus and 14.46% by plankton. The contents of nitrogen and phosphorus in suspended solids of Fuqiaohe Reservoir were0.257mg/L and 0.0143ml,respectively,among which the contents of nitrogen and phosphorus were 0.200mg/L and0.0072 mg/L in organic detritus, respectively, and 0.057mg/L and 0.0071mg/L in plankton, respectively. TSS could be used asan indicator determining trophic states of reservoirs and could also be used to predict production potentials of planktivorous fishes.
