In this Nov. 21, 2019 photo, wildlife officials hold dead Chinese pond mussels that were found in a network of ponds in Franklin Township, N.J. A colony of giant invasive Chinese mussels has been wiped out from the New Jersey pond. They had threatened to spread to the Delaware River and wreak ecological havoc, as they already are doing in other parts of the world. Officials say they’re confident they’ve narrowly avoided a serious environmental problem by eradicating the mussels from a former fish farm in Hunterdon County. (AP Photo/Wayne Parry)
