In a controversial move that has ignited the ire of conservationists and researchers, Australian Prime Minister Anthony Albanese has vowed to introduce legislation ensuring the continuation of “sustainable salmon farming” in Tasmania’s ecologically sensitive Macquarie Harbour. The pledge, made in a letter to industry group Salmon Tasmania, comes on the heels of years of intense lobbying efforts to curtail the local salmon industry and protect the critically endangered Maugean skate from the brink of extinction.
Albanese’s decision was informed by a recent report from the University of Tasmania’s Institute for Marine and Antarctic Studies (Imas), which indicated that the current Maugean skate population is “consistent with the long term average as at 2014.” The report highlighted positive signs attributed to oxygenation efforts in the harbour, as reduced dissolved oxygen levels pose the primary threat to the ancient ray-like species.
Even with this new and positive data, it is clear to me the Environmental Protection and Biodiversity Conservation Act – introduced 25 years ago – does not allow for a commonsense solution on an acceptable timeline.
I can confirm that the Australian government will introduce legislation to ensure appropriate environmental laws are in place to continue sustainable salmon farming in Macquarie Harbour.

Conservationists Warn of Maugean Skate Extinction
Despite the cautious optimism expressed in the Imas report, conservation groups remain deeply concerned about the fate of the Maugean skate. The Australian Marine Conservation Society (AMCS) asserts that a marginal improvement in population numbers is insufficient to safeguard the species from extinction, particularly if Macquarie Harbour were to experience another extreme weather event within the next decade.
Dr Leonardo Guida, AMCS shark expert, emphasized the strong correlation between intensified salmon farming and declining Maugean skate populations, stating, “The fate of the skate literally rises and falls alongside salmon production.” He further cautioned that the skates caught in recent years were predominantly aging adults nearing the end of their 10-12 year lifespan, casting doubt on the sustainability of the population uptick.
Political Backlash and Industry Support
Tasmanian Greens senator Nick McKim lambasted the prime minister’s pledge, arguing that Australia’s environmental laws are already too lenient. He decried the notion of further diluting them to “underpin corporate profits” as an “outrage and a betrayal.” Eloise Carr, director of The Australia Institute in Tasmania, echoed these sentiments, warning that rushing through special legislation to protect Macquarie Harbour farming operations would likely “condemn the Maugean skate to extinction.”
Conversely, the Tasmanian salmon industry, which generates approximately $1.3 billion in revenue and is a significant employer on the state’s remote west coast, has welcomed Albanese’s announcement. Jeremy Rockliff, Tasmania’s premier, pledged to “continue to do all we can to support our workers across all industries,” while state Labor leader Dean Winter asserted that the prime minister’s letter presents “an irrefutable case that salmon farming and the Maugean skate can coexist.”
The Path Forward: Balancing Conservation and Industry
As the debate over Macquarie Harbour’s future rages on, the path forward remains unclear. Prof Jayson Semmens, co-author of the Imas report, expressed cautious optimism about the Maugean skate’s population recovery but stressed the necessity of ongoing monitoring to ascertain the species’ long-term trajectory. A 2022 conservation report by the government’s threatened species scientific committee estimated that a mere 40 to 120 adult skates remain in the wild, underscoring the precarious nature of their existence.
As policymakers, conservationists, and industry stakeholders navigate this complex issue, striking a balance between environmental stewardship and economic sustainability will prove crucial. The fate of the Maugean skate, and the integrity of Tasmania’s unique marine ecosystem, hangs in the balance as the nation grapples with the consequences of its actions and the urgent need for a comprehensive, science-based approach to resource management.
- Maugean skate populations show marginal improvement, but long-term survival remains uncertain
- Conservationists warn special legislation could condemn species to extinction
- Tasmanian salmon industry welcomes pledge, emphasizes economic importance
- Balancing environmental stewardship and sustainable industry growth key to path forward
