Our Marine Campaign

Stop the fish farm faeces dump


Intensive fish farming in coastal areas is one of the greatest threats to Tasmania's marine values. While the industry started small, at just 53 tonnes a year in 1983, it now produces 40,000 tonnes a year and has plans to double production by 2030.  

The main reason open pen salmon farming damages the marine environment is because the industry doesn't bother to capture its waste - which just settles on the sea floor and enters the water column. Waste produced by salmon farming includes uneaten fish food, fish faeces and urine and organic matter from net-cleaning. 

Environment Tasmania is not against salmon farming, we just want the Government to regulate it properly to make sure fish farms don't go into areas that are high conservation value and can't support the amount of pollution salmon farming leaves in the ocean. Unfortunately, the industry is currently looking to expand into important conservation areas - like Tassie's stunning Sapphire Coast. Read our report on Cleaning Up Tasmanian Salmon here.



Nowhere else on earth

There is a secret marine wonderland under Tasmania's seas. While all Australians know about the Great Barrier Reef, very few know that Tasmania is a unique, global hot spot for marine biodiversity. 90 percent of Tasmania's marine life is found nowhere else on earth. Giant underwater kelp forests, the endangered spotted handfish, the Macquarie Island cormorant - these are just some of the species that only exist in Tasmania, the gateway to Antarctica. 

And yet just 1 percent of Tasmania's globally significant marine environment is protected. That means it is at risk of being destroyed by overfishing, climate change and poorly planned coastal development - before people even know it exists. Our mission is to stop this from happening.

Stop the Super Trawler!


Environment Tasmania is fighting hard to stop monster trawlers from industrialising Australia's oceans, and wiping out Tasmania's unique marine life with nets that could hold 13 jumbo jets.

    The Huon River and Dover is a Enviromental catastrophy. Somebody please help us down here. The Tourism motto for Tasmania should be: Pollution in Tassy is Fine, when its Below the Waterline.
    If the residents down here pumped raw sewage into the waterway they would be jailed. Yet Huon Aquaculture and Tassal are both pumping millions of tonnes into the pristine waters every year. They have the green light to double their production.

    Splendid Tasmania! Good luck with your environmental efforts. Can fish wastes be recycled into plant fertilizer?
