Seabed survey for a proposal extension to marine farm 8321, Wilson Bay, Pelorus Sound

Just Mussels LTD engaged NIWA to complete a benthic survey and assessment as part of a coastal permit application for an extension to marine farm 8321, in Wilson Bay, Pelorus Sound. This assessment comprised side-scan-sonar swath mapping of sites to characterise seabed topography, photoquadrats of the seabed to ground-truth the side-scans, samples of epifauana, diver observations and core sampling. The report indicated that the proposed extension is not expected to cause any significant adverse ecological effects. The ecological effects of farming the proposed additional mollusc species are likely to be no greater than the effects of farming green mussels. Farming of the algal species (as proposed) is unlikely to have any significant ecological effects. The report identifies a dense population of burrowing shrimp (Upogebia hirtifrons) adjacent to the inshore boundary of the site. However, the report notes that there is unlikely to be any significant detrimental effect of the proposed extension to the shrimp burrow habitat.

Purpose
The aim of that study was to provide a report on the habitats and the impact zone associated with the current activities at site 8321 and to identify any potential threats to any ecological, scientific or conservation values posed by the activities sought in the extension.
