Bay Area Bountiful

PopeyePopeye, the specially trained dog that will be sniffing around boats at Lake Sonoma this weekend, is something of a trend-setter, according to Sonoma County Supervisor Mike McGuire. The rapid spread of the unwanted mussels has created a burgeoning demand for dogs with this skill.

Mussel PipeThe invasive mussels do have some natural predators, says UGSG biologist Amy  Benson, but the fish and ducks that will feed on them aren't nearly numerous enough to contain the spread of the little bivalves. And once the mussels are established, she adds, eradication is barely possible in the best of circumstances.
