The Peninsula Daily News reports Aquatic Invasive Species coordinator Allen Pleus says officials as of July 6 trapped 51 male crabs and 36 females.
Pleus says the size of the crabs indicates they came from the same larvae group.
Dr. Emily Grason, Crab Team project coordinator through Washington Sea Grant, wrote in a blog post that the crabs likely floated to Sequim in 2016. But Grason says where they are coming from is still not determined.
Grason said resource managers expect to have an answer in a few months.
