Sculpins are one of the most abundant fishes in Pacific coastal streams and lakes, but they remain understudied despite potentially significant impacts to stream ecology. The poor swimming ability of sculpins limits their range by inhibiting passage of barriers passable to other fishes. Sculpins are voracious eaters and feed primarily on stream invertebrates. By sampling invertebrates in reaches of stream above and below a sculpin barrier, this study examined the impact sculpin presence had on the stream invertebrate community. Invertebrates were sampled in riffles using a Serber sampler (n = 4). The results showed that the presences of sculpins had a significant impact on the abundances of stream macroinvertebrates. Abundances of Ephemeroptera were dramatically lower in the presence of sculpins. This study warrants further research of greater scope and depth to more accurately determine the effect of sculpins on stream ecosystems.
