Evaluating the effects of artificial oxygenation and hypoxia on biota in the Upper Swan Estuary: Final report

In 2010, the Swan River Trust commissioned Murdoch University to evaluate the effects of artificial oxygenation on the benthic macroinvertebrate (BMI) fauna of the Upper Swan Estuary (USE). The project involved the collection of BMIs monthly between January 2010 and December 2011, at five locations in the USE between Ron Courtney Island and just upstream of Middle Swan Bridge (i.e. the Jane Brook confluence). Specifically, the project had two components; 1) to describe any spatial and/or temporal patterns in the BMI community during eight consecutive seasons in 2010 and 2011 and 2) to assess the ecological and management implications of the findings, with specific reference to the effects of hypoxia (low dissolved oxygen) and of the artificial oxygenation program
