Proposed Aquaculture Activities Regulations published in the Canada Gazette, Part I, Vol. 148, No. 34 – ORA

The proposed Regulations would open the way for aquaculture operations to deposit prescribed drugs, pesticides and other deleterious substances into aquatic ecosystems, when some have had well-documented adverse environmental impacts on ecosystems, and a recent Department of Fisheries and Oceans (DFO) report on the potential effects of anti-sea lice pesticides confirms the importance of a site-specific approach to substance deposit regulations.[1] The problems associated with these operations necessitate consistent and strong national standards and monitoring, to ensure these operations meet the most vigorous environmental protection.
