GEOGRAPHICAL VARIATION OF THE PARASITE, PHYLLOBOTHRIUM DELPHINI (CESTODA), IN BALL'S PORPOISE, PHOCOENOIDES DALLI , IN THE NORTHERN NORTH PACIFIC, BERING SEA, AND SEA OF OKHOTSK
A bstract Prevalence of the larval cestode, Phyllobothrium delphini , was estimated from 2,445 Dall's porpoise, Phocoenoides dalli , from the incidental take of the Japanese high seas salmon drift‐net fishery in the northwestern North Pacific Ocean, Bering Sea, and a local hand harpoon fishery...
