National Level
Formal national protection in place
Pearling and pearl farms for P. maxima, are managed by the Department of Fisheries Western Australian (DFWA) under the provisions of the Pearling Act 1990.
Is the use part of a strategy to generate conservation incentives, to finance conservation, or to improve tolerance/stewardship?
Unknown/not recorded
Is there evidence that the use is affecting the conservation status of the species? HIDE
Unknown/not recorded
Is there evidence that the use is affecting natural selection?
Unknown/not recorded
Is there evidence that the use is affecting poaching of illegal wildlife trade?
Unknown/not reported
Is there any evidence that this use of the species is having a knock-on effect on the status of non-target species
Unknown/not recorded
No
Yes, considered sustainable
Additional Details (if available)
Clearly establishing facilities for the pearling industry has some effect on the habitat. However the farms are small when compared with the vast distances on the north coast of Western Australia. They are also predominantly situated over mud bottom for maxi- mum pearl growth. The major impact is the visual presence of the longlines, which are floating in the water, except for an anchor on each end, which is placed in the mud bottom
Details of assessment carried out
Thirteen environmental and ecological issues were identified across the P. maxima fishery. None were considered to be high risks; all were ranked as either moderate (23%) or low (77%); The industry is considered to be environmentally benign. However, recommendations are made on how to further minimize risk.
Has a valuation of financial flows from this use at the site/national/international level been recorded
