An environmental group, Neighbors of Fish Farming (NOFF), has installed a billboard criticizing Australian Minister for the Environment and Water Tanya Plibersek for her role in approving the expansion of salmon farming in Macquarie Harbor, which they claim is driving the Maugean skate towards extinction. The group is also urging seafood certification bodies to withdraw certifications from farms in the harbor and supermarket chains are accused of 'greenwashing' by misleading consumers about the sourcing of salmon. The university's study links the decline of the Maugean skate to aquaculture, but the salmon industry insists it is working with the government on conservation efforts, including a new program to increase dissolved oxygen levels in the harbor.
