A new study estimates that mangroves prevent over $65 billion in damage from coastal storms every year, and says mangrove protection should be funded in the same way as infrastructure like seawalls.
Combining aquaculture and hydroponics, aquaponics unearths value in “waste” flows and re-routes them back into the economy. It’s an inspiring example of how a circular-economy business model can work.
Entire populations of prawn ‘super-females’ are now being commercially distributed. The science behind this continues to advance and could have a far-reaching impact on both humans and animals.
The World Heritage Listing for Victoria’s Budj Bim fish traps was ground-breaking. Here are five other Australian Indigenous sites that also deserve greater attention.

Analysis of last summer’s heatwave shows it killed farmed salmon and decimated kelp forests, as well as shifting grape harvests and fish spawning times forward by several weeks.
Rising seas and groundwater depletion, both driven by climate change, are making soils saltier in many parts of the world. Farmers will need help adapting, especially in developing countries.
Many people focus just on agriculture and new technologies for feeding the world’s growing population. Yet, fisheries are the centerpiece of billions of people’s diets.
Oysters are big business along the Gulf Coast, but raising them off-bottom – which yields a premium product – is just starting there. Hurricane Michael showed it won’t be easy.
Many critics say that fish farms mainly sell their output to wealthy countries and don’t provide much benefit to poor people in producing countries. Three aquaculture experts show why this view is wrong.

Oysters grow in seawater and filter their food from it, so how do you shield them from waterborne diseases? Scientists are working to develop strains that are resistant to a fast-spreading herpes virus.
A new study shows that sustainable fish farming in deep ocean waters could produce as much seafood as all of the world’s wild fisheries, in a space the size of Lake Michigan or Africa’s Lake Victoria.
In an extract from his new book, Tim Flannery explains how giant kelp farms could suck carbon dioxide from the air and store it in the ocean’s depths, while encouraging species like fish and oysters.
Due to rising sea levels, low-lying island nations are in immediate danger. If drastic measures are taken, this disastrous trend can be transformed into an opportunity for sustainable development.
