observed that reservoir enclosures stocked with
silver carp, an obligative filter feeder, developed phytoplankton communities dominated
by small phytoplankton whereas the
physically larger phytoplankton dominated the Congo tilapia, facultative filter feeder, stocked
enclosures. Large cell, filamentous and colonial cyanobacteria are retained on the
branchial filtering apparatus of silver carp while phytoplankton < 10 Am are not filtered
from the water column
