First Record of Nematode Larvae in the Amphipod Ischyrocerus commensalis Colonizing Red King Crabs in the Barents Sea
In this study, nematodes were first reported in the amphipods, Ischyrocerus commensalis, collected from the introduced and commercially important red king crabs, Paralithodes camtschaticus, in the coastal Barents Sea in July 2022. Commensal amphipods were registered on all red king crabs captured (n...
