Seeing those parasites on river-caught fish indicate to river anglers that they are "fresh" from the saltwater, as sea louse can only survive a few days fresh water. Though there are also a number of fresh water salmon parasites. Sea louse are generally harmless to adult fish, but can be detrimental to the health of juvenile fish. Hence the danger of fish farms that sit in the path of smolt migration routes. Fish farms are known to be parasite-breeding factories.
