Book excerpt: "In 2006, the Nova Scotia Department of Fisheries and Aquaculture (NS DFA) reported on the results of their Environmental Monitoring Program (EMP) for the marine aquaculture industry from 2003 to 2005. For regulatory purposes, total dissolved sulphide levels in sediments are the main parameter used to determine direct impact of an aquaculture operation. Monitoring results (2003-2005) indicated that only a few finfish monitoring stations reported sulphide levels in the B - hypoxic (polluted) category and one station reported sulphides in the C - anoxic (grossly polluted) range. Virtually all of the shellfish sites reported sulphides in the A - oxic (normal) range. An update on sulphide monitoring results for finfish aquacultures sites from 2006 to 2011 indicated a significant increase in the number of finfish monitoring stations reporting B - hypoxic (or polluted) and C - hypoxic (or grossly polluted) conditions compared to the 2003-2005 monitoring period. The results also indicated that overall environmental quality associated with finfish sites had decreased since the 2003-2005 reporting period. The effectiveness of NS DFA's new 2011 Environmental Monitoring Program Framework to ensure aquaculture sites maintain oxic levels has yet to be demonstrated or evaluated"--Summary.
