Waterways in Japan are being overrun with non-native fish species, including American natives like black bass and blue-gill (Lepomis macrochirus). While the Japanese apparently like sport fishing for black bass and other non-natives, they don't like eating them. Commercial fishermen are bearing the consequences, pulling up tons of fish that no one wants. According to The Yomiuri Shimbun, the Ueno Zoo in Tokyo now accepts donations of these fish and feeds them to its sea lions and birds. This is much better than the alternative, which was basically letting the catches rot while trying to find a way to dispose of them, but is likely a short-term solution.
