dc.description.abstract

The purpose of this study was to analyze the production of the benthic macroinvertebrates in a commercially navigated river in order to assess the environmental impacts of increasing levels of traffic. Production was estimated for 16 taxa at two sites in the Winfield navigational pool (Upper Winfield - UW; Lower Winfield - LW). Total production of all taxa on cobble/pebble substrates was 43,838 mgDW/m2/yr at UW and 16,553 mgDW/m2/yr at LW. Production on sand/silt substrates was lower, 3,534 mgDW/m2/yr at UW and 2,405 mgDW/m2/yr at LW. On cobble/pebble substrates the production was mostly accounted for by Diptera (76.0% UW, 85.2% LW), Trichoptera (12.4% UW, 5.8% LW), and Ephemeroptera (10.8% UW, 5.8% LW). On sand/silt substrates virtually all production was accounted for by Diptera. Total macroinvertebrate production for an "average" square meter of the Winfield Pool was estimated as 6,228 mgDW/m 2/yr.
