TOKYO-In an unusual twist to the string of recent high profile and serious threats to U.S. fisheries from exotic, invasive species, two North American gamefish are staging their own invasion of the Far East.
In the moat surrounding Japan's imperial palace, non-native black bass and bluegills are threatening native species, prompting the Japanese Environment Ministry to drain sections of the moat to kill the exotics.
"We just cannot stand there watching our indigenous fish, such as gobies, being eaten up by such strong foreign species," said ministry spokeswoman Sae Sato.
The decline of native Japanese fish species has been a growing concern in Japan since fish from North America were introduced decades ago. Particularly worrisome species are robut black bass and ravenous bluegills, which tend to feed on local fish.
