Marine Biologist Morton Discovers Sea Lice on Herring

Alexandra Morton took pictures of herring covered in sea lice on July 18th, off of a dock near northern Vancouver Island. “There were thousands of herring, all of which were very young. Sea lice on herring this small (about 4cm long) were never reported before salmon farms arrived. These lice appear to be Caligus, which are also found on farm salmon.” According to Alex, the tiny herring must have passed through an area with a lot of adult lice- her educated guess is salmon farm feedlots.
