Artificial reefs made from innovative, low-carbon emission materials have the potential to improve biodiversity around aquaculture sites and may even open up opportunities for multi-trophic aquaculture, according to Max Morgan-Kay of ARC Marine.

A new project that aims to investigate growing kelp and mussels alongside offshore wind turbines – as well as researching the potential for artificial reefs – has been awarded a NOK 84 million (£7 million) grant.

Massive floods in Assam, north-east India, have caused severe damage to the state’s fish farms, dashing farmers’ expectations of a profitable season.

"Kelp won't help," says University of Tasmania researcher John Barry Gallagher in an article in The Conversation on kelp's status as a carbon buster.
