Maine faces mounting controversy over industrial salmon farming operations managed by multinational companies such as Cooke Aquaculture. Conservation groups, including the Conservation Law Foundation, have filed federal lawsuits alleging Clean Water Act violations due to open-water net pens creating oxygen-depleting waste and toxic benthic sludge. Traditional fishers and lobstermen report crowded fishing grounds, floating debris, and disrupted gear near expanding marine dead zones. Furthermore, recent mass die-offs driven by high temperatures, low oxygen, and disease have intensified public scrutiny over environmental biosecurity. Animal welfare organizations have also criticized hatchery sanitation standards following undercover investigations. In response, industry representatives defend modern mitigation practices like hot-water delousing baths and periodic site fallowing. Meanwhile, frustrated coastal Maine municipalities are increasingly attempting to assert local regulatory control over aquaculture sitings to address perceived enforcement gaps at the state level.
