| Abstract: | Study of the feeding capacity of silver carp and bighead carp by means of experimental ecology showed that the filtering frequency
of silver carp was slightly greater than that of bighead carp, but that the latter's suction volume was much greater than
the former's so the filtering rate (filtering frequency multiplied by the suction volume) of silver carp was smaller than
that of bighead carp. The filtering efficiency of silver carp for phytoplankton was greater than that of bighead carp for
them. The removal rates of silver carp for phytoplankton were greater than those of bighead carp, but for zooplankton the
former were smaller than the latter. For food particles about 70 μm both removal rates were almost equal. The feeding habits
of the two species in natural waters is also discussed in the paper. |
