As wild fish and other marine species get scarcer from overfishing and demand for ‘blue foods’ grows around the world, farming of the ocean is growing rapidly. Fish, kelp, prawns, oysters and more are now widely farmed. The world now eats more farmed seafood than wild-caught.
These farms are springing up along coasts and in offshore waters worldwide. Australians will be familiar with Tasmania’s salmon industry, New South Wales’ oyster farms, and seaweed farms along the southern coastline. Aquaculture is already larger than fishing in Australia. Farming the sea is hailed as a vital source of food and biomass essential to reduce the damage we do to our oceans and help feed a growing population.
But the booming “blue economy” is no panacea. Fish farms can pollute the water. Mangroves are often felled to make way for prawn farms. The solutions of today could turn out to be problems of the future. We cannot simply shift from one form of environmental exploitation to another.
There is an alternative: permaculture. This approach has proven itself on land as a way to blend farming with healthy ecosystems. What if it could do the same on water?
