Marine Industry and Infrastructure Monitoring

Aquenal has performed literally hundreds of environmental baseline surveys and follow-up monitoring surveys of marine finfish and shellfish farms. Surveys have been performed in temperate through to tropical environments ranging from shallow, sheltered bays to open ocean coasts and deep river estuaries, in depths of up to 45 m. Our experience working with the marine farming industry dates back to Aquenal’s inception in the mid 1990s, and we are now recognised as one of the most experienced consultants in the field of marine farm environmental monitoring in Australia. Aquenal has also performed monitoring programs for other marine industries and infrastructure projects, many of which are linked to our impact assessment studies. …Further information

Marine farm environmental surveys

In Tasmania over the past 12 years, we have performed baseline and monitoring surveys of over 60 individual marine farms involved in the culture of finfish (Atlantic salmon, rainbow trout), subtidal shellfish (Pacific oysters, blue mussels) and intertidal shellfish (Pacific oyster). We have also been commissioned to perform a broadscale environmental monitoring program of salmon farming areas in south eastern Tasmania, involving monitoring of water and sediment quality and benthic community health.

Aquenal has also conducted environmental baseline and monitoring surveys of finfish (barramundi) farms in the Tiwi Islands, Bynoe Harbour and Port Darwin in the Northern Territory.

Parameters surveyed depended on the species cultured and nature of the marine farm site, however methods routinely included filming and assessment of the seabed, and sampling and analysis of sediments and macroinvertebrate communities. Surveys in the Northern Territory also included mangrove mapping and water quality and current analysis.

Monitoring of other marine industries and infrastructure

Examples of monitoring programs for other marine industries and infrastructure projects are listed below and relate primarily to discharges of pulp mill and sewage effluent, as well as thermal power station discharges, stormwater runoff and dredging activities:

  • Monitoring design, on the basis of MBACI principles and associated statistical power analysis, and implementation of a marine ecological monitoring program to collect pre-operational data at the proposed ocean outfall site of the Gunns pulp mill
  • Sediment and biological monitoring at dredging and disposal sites for the Port of Burnie dredging project
  • Annual and subsequent biennial monitoring surveys of Donovans Bay in the Tamar Estuary to assess the impacts of thermal discharges from the Bell Bay Power Station on the basis of biological performance indicators
  • Biological and water quality monitoring to assess any changes in environmental conditions following consolidation of two outfalls and infrastructure upgrades at the Burnie sewage treatment plant
  • Macrobenthic and water quality monitoring to assess impacts of stormwater runoff from a woodchip plant in the Tamar Estuary
