Fish passengers have been found off the Oregon coast in the wreckage of a boat that appears to be debris from the 2011 Japanese tsunami.
Scientists say 21 yellowtail jacks and one Asian striped knifejaw hitched a cross-Pacific ride in the bow of the boat found last week.
Fish washed up in debris could bring parasites and diseases to native species, but biologists say the latest fish pose little threat.
However, they were quarantined at the Oregon Coast Aquarium.
