The World Wide Fund for Nature (WWF) hopes to use blockchain technology to make the entire seafood supply chain traceable. Working with tech startup TraSeable, fishing company Sea Quest and blockchain company Viant, WWF is running a pilot project to trace tuna through the supply chain by tagging catches with radio-frequency identification chips and QR codes - which can be scanned by a mobile phone.

Many important marine species, including marine mammals, sea turtles and seabirds, are threatened by bycatch - i.e. being accidentally caught by fishers who are targeting other species. A new paper finds that around half of the populations threatened by bycatch could be protected by managing fish stocks to maximise fishery profits, which would reduce bycatch as a side-effect of reducing overfishing.

This book, edited by Faisal I. Hai, Chettiyappan Visvanathan and Ramaraj Boopathy, discusses the social, economic and environmental sustainability implications of various aquaculture practices.

Building UK fish stocks up to their maximum sustainable yields could increase fish catches by 27%, create 5,100 new jobs and add £319 million to the UK’s GDP, NGO Oceana reports. Oceana points out that Brexit may provide a window of opportunity to change the UK’s fishing practices for the better.

Genetically modified salmon could potentially be on the US market by 2019.

This paper presents the findings of a large-scale study which used global tracking data on sea-going vessels to characterise the scale, distribution and drivers of the global fishing effort.

The world’s first insect-fed salmon has been launched by insect producer Protix.

Fish are generally seen as more efficient in converting feed into food than land-based species, but, according to a new paper, this conclusion does not hold if the retention of protein and calories is accounted for using a different measure.

Monterey Bay Aquarium Seafood Watch, Liberty Asia and the Sustainable Fisheries Partnership have created a database to help corporate seafood buyers check fisheries for risk of slavery, forced labour and hazardous child labour.
