Idaho Fish and Game says the Redwood Park Pond in Boise presented a clear and present danger.
"We get very concerned it could get into the wild." says Joe Kozfkay with Idaho Fish and Game, "if this got into the river it could be very very bad." He's talking about the rosy red shiners. A nice fish for a tank, but a real problem in the wild. "Worst case scenario, they become so prolific they overtake entire river systems large water bodies, reservoirs," says Kozfkay, "and eat all the food and crash native species and sport fish."
And you might say, how on earth could a tiny fish make his way from a pond to a river? Fish and Game says it's easier than you think ... drain tubes leading to runoff ditches that can eventually lead to a river. So, they take no chances. Next year, the pond will be stocked with largemouth bass and bluegill.
