  • Can governments ensure "no net loss" of physical and chemical habitat from new Great Lakes cage cultures through impact predictions and modeling combined with licensing/permitting? If no, then what does the "precautionary approach" indicate for approvals/permitting?
  • What are the priority research needs?
  • What monitoring strategies are needed and are in place?
