Abstract

<p>We report the first record of the domestic invasive species, Coreoperca kawamebari (Perciformes: Sinipercidae), in the Uso River system, Shiga Prefecture, Japan. This species has not been observed in previous studies of fish fauna in this vicinity, thus it was likely introduced recently. We caught mature adults and yearlings, indicating that this species has reproduced in this river system. Based on stomach content analysis, this species feeds on aquatic insects such as midge and mayfly larvae, suggesting possible risk, derived from predation pressure and competition, on the ecosystem of the Uso River system.</p>
