An iron in the fire: How iron sulfide could turn fish farms into climate solutions
- News item

The following article by Bonnie Waycott, explores how aquaculture could become an unexpected ally in the fight against climate change. Research shows that adding iron to fish farm sediments may not only neutralise harmful hydrogen sulfide but also lock away hundreds of millions of tons of CO₂ each year. This approach could transform farms in aquaculture-heavy nations like China, Indonesia, and India into powerful carbon sinks.
At the same time, studies in the Baltic Sea highlight the role of mussels, which store carbon in their shells and could offer long-term climate benefits. Together, these findings point to fish farms and shellfish as surprising tools in both reducing emissions and advancing sustainable seafood.
