Coles, a major Australian supermarket chain, has decided to decrease its salmon purchases from Macquarie Port in Tasmania due to concerns over the endangered Maugean skate, a local species. This decision comes in response to pressure from shareholders and environmental groups. Macquarie Port, where three large salmon farming companies are based, is facing challenges due to hydroelectric dam construction, fishing, mining, and climate change, all of which are impacting the local ecology. Despite the government's renewal of the operating license for a farm in the port, opposition remains strong, with a billboard campaign and shareholder actions targeting domestic farmed salmon. Coles has supported conservation projects and balanced the interests of various stakeholders, but has not disclosed the exact reduction in its salmon purchases.
