Abstract
Significantly higher concentrations of suspended inorganic matter were observed in the outflows than the inflows of three impoundments along an urban stream in southern Ontario during baseflow conditions. This pattern was observed during two summers at two of the reservoirs. After carp (Cyprinus carpio L.) were eliminated (490 kg ha-1) from the third reservoir, significantly less suspended sediment was found in the outflow. Burrowing benthic invertebrates (Chironomus sp. and Tubificidae) which dominated the benthic fauna were replaced by less tolerant, more lithophilic taxa after carp removal. Tubifids dominated the fauna again after carp recolonized the impoundment. These data suggest that carp removal can have a significant positive effect on water quality.
