With golden mussels now confirmed in California waterways, the focus has shifted from detection to defense. On Monday, local leaders toured the Port of Stockton—where the invasive species was first spotted in North America just 10 months ago—to highlight the growing efforts to stop the mussels before they cause widespread damage to critical water infrastructure. … [Rep. Josh] Harder and other California Democrats are backing a $15 million bill in Congress to create a task force that would research, prevent, control and eradicate golden mussels. The bill is currently in committee. Meanwhile, scientists at a Davis-based lab are already testing a potential biological solution.
