Early‐stage sea lice recruits on Atlantic salmon are freshwater sensitive
Abstract Sea lice are significant parasites of marine and brackish farmed fishes. Freshwater bathing is a potential control option against numerous sea lice species, although has been viewed as futile against those that are capable of tolerating freshwater for extended periods. By comparing freshwat...
