Plants and seedlings of Potamogeton pectinatus were obtained from tubers grown under laboratory conditions. Four plants (mean total length: 14.3 m) and two seedlings (mean height: 10.9 cm) were placed in each of twenty 1001 aquaria illuminated with fluorescent lighting. A 5 cm-thick layer of muddy sediment was then put in each aquarium together with two size-matched fish (mean size classes: 6.8, 14.1 and 23.0 g) of the species Cyprinus carpio. After four weeks, the total length of the plants in the control and small fish aquaria had increased by 71% and 3% respectively, whereas plant total length in the aquaria with medium and large fish had diminished by 33% and 76%, respectively. Few seedlings survived in the presence of the fish. The reduction in plant growth was associated with an increase in water turbidity in all treatments as a result of the benthic feeding habit of C. carpio, and of direct herbivory action in the case of medium- and large-sized fish.
