| Impact Description | Ephemeroptera, Plecoptera, Trichoptera ratios were lower in streams with round gobies and the percent Chironomidae was higher. These results suggest that streams invaded by Neogobius melanostomus have experienced a reduction in mayfly/stonefly/caddisfly abundance with a resultant dominance by midges. |
