Salmon Science Open House

On 25th June 2022, our scientists were part of a joint FRDC, IMAS and CSIRO Salmon Science Open House held on the Hobart waterfront. This public ‘drop-in’ event was all about showcasing the science we do, and chatting with curious and passionate visitors about the science of monitoring, observing and modelling the effects of salmon […]

New research exploring opportunities for potential future finfish aquaculture expansion in Tasmanian waters

Researchers at IMAS and the School of Geography, Planning and Spatial Sciences have recently completed a research project developing a decision-support tool to aid spatial planning for finfish aquaculture in Tasmania. This project was a collaboration with the Department of Primary Industries, Parks, Water and Environment (now Department of Natural Resources and Environment Tasmania) under […]

New monitoring tool to improve our understanding of how finfish aquaculture influences planktonic communities

New research from Sharon Hook (CSIRO), Camille White and Jeff Ross (Salmon Interactions Team, IMAS) has highlighted the potential of using microbial gene expression as a tool for understanding more about how microscopic plants and animals which float in the water column (planktonic communities) are affected by finfish aquaculture.  Finfish aquaculture releases nutrients, including nitrogen, into the surrounding water […]

Rocky Reef Assessment in the Derwent Estuary

Our team at the Institute for Marine and Antarctic Studies (IMAS) has recently published a new report looking at the health of rocky reefs in the Derwent estuary. We used our new Rapid Visual Assessment methodology that has been developed to identify the early signs of organic enrichment on reef ecosystems.   This project was initiated in 2019 when the Derwent Estuary Program (DEP) engaged our team to undertake a rocky […]

Developing an environmental monitoring program for Storm Bay

Our team at the Institute for Marine and Antarctic Studies (IMAS) is currently involved in a large FRDC project (‘Storm Bay Observing System’) designed to assess the environmental performance of salmon aquaculture in Storm Bay. Through this project we are monitoring the interactions between salmon farms and the whole ecosystem, including soft sediment, inshore reefs, […]

Reef condition in the southern D’Entrecasteaux Channel

The intensification of human activity in the lower D’Entrecasteaux Channel has led to increased concern regarding the effects of sustained low-level organic enrichment on the health and function of rocky reef ecosystems in this region. Our team at the Institute for Marine and Antarctic Studies (IMAS) has been developing and trialing a “Rapid Visual Assessment” […]

New spatial data assessment to assist the future management of Tasmanian Waters

Spatial data describes any geo-referenced data that contains information about its specific location, this can include environmental conditions (e.g. seabed type), human activities (e.g. recreational and commercial fishing) and socio-economic values. As such spatial data can be used to create decision-support tools that can assist planning for and assessment of primary industries operating in the […]

Soft-Sediment communities key to assessing impacts of salmon farms

Studying soft-sediment communities is key to assessing the environmental impacts of salmon farms – and it’s helping salmon producers monitor and manage their operations for a sustainable industry, now and into the future. IMAS researchers are regularly out sampling sediments, which means there’s often a stockpile of post processing to do. It’s a huge undertaking […]

Improved environmental conditions in Macquarie Harbour

IMAS researchers today released the latest results of surveys of environmental conditions in Macquarie Harbour, carried out as part of ongoing monitoring of oxygen dynamics and conditions on the bottom of the harbour. The report provides an update on the status of dissolved oxygen (DO) and benthic conditions in the harbour and follows previous reports […]
