“…However, our simulation results indicated that even at peak ruffe biomass, its impacts on many groups were relatively minor. These results are similar to observations in the St. Louis River estuary, where two decades after the ruffe first invaded there has not been any obvious negative impacts of ruffe on yellow perch or other fishes (Peterson et al 2011). The immediate declines of yellow perch and other native fish populations in the St. Louis River following the ruffe invasion were more likely the result of fluctuations in natural population dynamics rather than interactions with ruffe (Bronte et al 1998).…”

“…Our simulations of potential biomass of the three invasive species in Lake Erie were within the ranges observed for those species in other waters. In its native range, ruffe densities vary widely from 0.26 kg ha -1 to 210 kg ha -1 (Kováč 1998), while in in Lakes Superior's St Louis River Estuary, ruffe densities peaked at 1892 individuals ha -1 (* 32 kg ha -1 assuming an average mass of 17 g) soon after establishment (Peterson et al 2011). Killer shrimp biomass reported in European rivers were as high as 50-70 kg ha -1 wet weight (Berezina1 and Ď uriš2 2008).…”

Assessing the potential for aquatic invasive species (AIS) to impact ecosystem function and services is an important component of ecological risk assessment. This study focuses on quantifying changes in biomass of food web groups in response to changes in AIS biomass as a function of variable AIS prey vulnerabilities (i.e. food availability) and AIS vulnerabilities to predators (i.e. predation pressure). We modified an existing Lake Erie food web model to assess the potential food web impacts of three benthic AIS (Eurasian ruffe Gymnocephalus cernua, killer

“…The eDNA results described here constitute a contribution toward a Great Lakes basin-wide surveillance program and augment the many efforts targeting other species that are based on traditional sampling tools. For example, US Environmental Protection Agency has tested the sampling efficiency of traditional sampling tools for plankton, benthic invertebrates, and fishes (Peterson et al 2011). However, most Great Lakes species surveillance efforts are focused on one or a few species and (or) are geographically narrow.…”

Environmental DNA (eDNA) is a sensitive technique for early detection of rare species, including bighead (Hypophthalmichthys nobilis) and silver (Hypophthalmichthys molitrix) carp, which are incipient invaders of the Great Lakes. Since 2009, 2822 samples have been collected from the Great Lakes basin to delimit the extent of Asian carp incursions. Samples collected in the Chicago Area Waterway System and in the western basin of Lake Erie indicate the presence of Asian carp DNA in the Great Lakes. These positive eDNA detections are within 6 and 4 km from where bighead carps were recovered in Lake Calumet, near Lake Michigan (2010), and from Sandusky Bay, Lake Erie (2000), respectively. To implement a Great Lakes surveillance plan for protecting imperiled species and reducing damages from invasive species, federal, state, and provincial agencies will need to cooperatively plan and implement a surveillance program that employs the unique strengths of multiple sampling tools, including eDNA methods.

“…There was early evidence that ruffe growth declined as their density increased in the Saint Louis River Harbor [5], but formal analyses of growth related to population density have not been reported for ruffe in North America. Although lengths have been reported along with CPUE (e.g., [35]), aging data, length at age, or growth rates are lacking in population assessments (e.g., [35,36]); these data for ruffe and their competitors would be useful to determine the effects of ruffe in invaded environments.…”

Competition between Invasive Ruffe (Gymnocephalus cernua) and Native Yellow Perch (Perca flavescens) in Experimental Mesocosms

Ruffe (Gymnocephalus cernua) were introduced to North America from Europe in the mid-1980s and based on similar diets and habit use may compete with yellow perch (Perca flavescens). To examine competitive interactions between invasive ruffe and native yellow perch, individually marked perch and ruffe were placed in mesocosms in a small lake. Mesocosms allowed fish to interact and feed on the natural prey populations enclosed. In the first experiment, four treatments were assessed: 28 perch, 14 perch + 14 ruffe, 14 perch, and 7 perch + 7 ruffe. Yellow perch growth was significantly lower in the presence of ruffe (ANOVA, p = 0.005) than in treatments containing only perch. In a second experiment, an increasing density of one species was superimposed upon a constant density of the other in parallel treatment series. Growth rates of both ruffe and perch declined when ruffe density was increased (t test, p = 0.006). However, neither ruffe nor perch growth was affected by increasing perch density. Total stomach content mass of perch was significantly decreased by ruffe in both years (p < 0.02), but no effects of ruffe on the composition of perch diets were observed. Ruffe growth and food consumption was greater than that of perch for both experiments. Ruffe can outcompete yellow perch when both species depend on a limited benthic food resource. Thus there is reason for concern for the ecological effects of ruffe if they expand their range into Lake Erie or North American inland lakes that contain yellow perch.
