Seaweed aquaculture and kelp forest restoration are getting a tentative nod as a blue carbon strategy – but the way policymakers structure carbon credits and offsets may make its benefits theoretical instead of bankable.
Dr Marta Carvalho is a post-doctoral researcher at the University of Las Palmas de Gran Canaria, where she studies novel Omega-3 sources for fish feed.
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.
While the oceans are still hugely efficient at producing bivalves such as mussels and oysters, it would be complacent not to consider a future when producing them in urban environments had its merits.
A commercial-scale, modular, stacked aquaculture system that’s capable of producing between 50 tonnes of shrimp a year with minimum human intervention is set to be operational in Singapore in 2023.
A French startup has started producing a novel material – Scalite – that’s made entirely from farmed tilapia scales and can be used as an attractive and environmentally sustainable alternative to wood and plastic.
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.
A British startup and its Chilean strategic ally are in the process of developing a 174 metre mobile fish farm that could be capable of producing up to 5,000 tonnes of salmon per cycle.
