Completed Research Projects

We undertake a wide variety of projects exploring the interactions between salmon farming and the environment

The Salmon Interactions Team undertakes a wide variety of research projects to better understand the Tasmanian coastal environment, society and the way they interact with salmon aquaculture.

All of our projects incorporate a wide variety of skills and expertise from data collection, data analysis, interpretation and write up – making these a real team effort.

Completed Projects

Sense-T stage 2: sensing Macquarie Harbour

This Sense-T project brought together the Tasmanian Salmonid Growers' Association, IMAS and CSIRO to collect and analyse data from salmon farms in Macquarie Harbour. Sensors were attached to individual 'sentinel' fish in pens in addition to sensors in the environment. Data was collected on fish behaviour as well as environmental conditions such as water temperature, […]

Characterisation of sediments in Port Esperance

This project aimed to determine whether salmon aquaculture contributes to sedimentation on reefs in areas where they co-occur.

Uptake of aquaculture waste by keystone reef species

Using a lipid biomarker approach, this project aimed to determine whether aquaculture waste supplements the diet of key mobile invertebrate species (abalone, Haliotis rubra; sea urchins, Heliocidaris erythrogramma; and benthic shrimp, Palaemon intermedius) within reef ecosystems in south-east Tasmania.

From global ideals to local realities – the foundations of sustainability

The focus of this project is the development of robust indicators for social, economic and environmental aspects of sustainability in aquaculture. A vast number of standards and indicators have been developed worldwide, however little is known about the use of these indicators, nor what aspects are missing/contradictory/overlapping/ inadequate. It is these aspects that this project […]

Determinants of socially-supported fisheries and aquaculture

Societal support is of great importance for developing successful fisheries and aquaculture industries, but how to gain support is less well understood. This purpose of this project is to explore existing learnings to better understand societal support in the context of fisheries and aquaculture and present the findings to industry in an accessible format.

Macquarie Harbour dissolved oxygen assessment

Dissolved oxygen within the water column is an important variable in Macquarie Harbour. This project was set up to collate and check EPA and industry monitoring data; to analyse historical time series of bottom water DO, salinity and temperature; to assist with analysis of factors related to bottom water DO including river flow, along- and […]

Understanding the ecology of Dorvilleid Polychaetes in Macquarie Harbour - FRDC 038

Farming salmon in Macquarie Harbour has highlighted a number of challenges over the years. The purpose of this project was to better understand the response of the environment to salmon farming by exploring the response of an environmental indicator (Dorvilleid polychaetes) to farming in the harbour. In the first part of the study, the international […]

Movement, habitat utilisation and population status of the endangered Maugean skate and implications for fishing and aquaculture operations in Macquarie Harbour

This project aimed to further explore the spatial distribution and ecology of the Maugean Skate, a species only known to exist in two estuarine systems located on the west coast of Tasmania (Macquarie Harbour and Bathurst Harbour. For more details on this project go to the final report: Movement, habitat utilisation and population status of the […]

An evaluation of the options for expansion of salmonid aquaculture in Tasmanian waters

The aims of this project were to explore how information can be used to assist in the evaluation of options for the expansion of the salmonid aquaculture industry in Tasmania. This involved identifying the types of information needed, identifying the data availability (and data gaps) within a study region, assessing different ways that the information […]

Characterising benthic pelagic interactions in Macquarie Harbour - organic matter processing in sediments and the importance for nutrient dynamics

The objective of this project was to examine the relationship between nutrient flux rates, nutrient pathways and also sediment and water variables in Macquarie Harbour in relation to salmon fish farming to help create an ecologically sustainable fish farming practice. The information and data obtained from this project was used to calibrate existing water column […]

Evaluation of approaches to improve sediment remediation (rate and function) under salmonid fish cages

This project provides a review and ranking of possible  options for active sediment remediation under Tasmanian conditions, and then tested the viability of selected options in the lab and in the field.

Planning for a blue future salmon – informing R&D, regulation and industry development

The Tasmanian salmon industry has a vision for safe and sustainable growth in production over the next two decades, while increasing tangible benefits to the Tasmanian community. To support this development, scientists, industry, regulators and non-government organisations collaborated to draft an integrated roadmap for the future of the industry: The Report from the Global Salmon […]

Development of novel methods for the assessment of sediment condition and determination of management protocols for sustainable finfish cage aquaculture Operations

The purpose of this project was to develop new environmental monitoring methods for evaluating the level of sediment degradation in association with finfish cage aquaculture in south east Tasmania. Using these methods, the aim was to explore ways of incorporating these techniques into farm management protocols in order to promote sustainable aquaculture production. The findings of […]
