The Sea Around Us’ Deng Palomares and Daniel Pauly have just added a new item to their long list of publications: a chapter in Elsevier’s book Coast and Estuaries: The Future.

In their contribution, titled “Coastal fisheries: the past, present and possible futures,” Palomares and Pauly highlight the importance of coastal fisheries by pointing out that they made up 55 per cent of global marine fisheries catch from 2010 to 2014.

Carbon dioxide emissions from the fuel burnt by fishing boats are 30 per cent higher than previously reported, researchers with the Sea Around Us initiative at the University of British Columbia and the Sea Around Us – Indian Ocean at the University of Western Australia have found.

In a study published in Marine Policy, the scientists show that 207 million tonnes of CO2 were released into the atmosphere by marine fishing vessels only in 2016. This is almost the same amount of CO2 emitted by 51 coal-fired power plants in the same timeframe.

Fishing pressure and climate change challenge Tokelau’s food security

Tokelau’s fish-dependent population may be at risk of seeing its main source of locally available animal protein dramatically reduced if the amounts and species of fish caught by local fishers in their waters stay the same or increase.

According to a study by researchers with the Sea Around Us initiative at the University of British Columbia and the Sea Around Us – Indian Ocean at the University of Western Australia, a small-scale, commercial or artisanal fishery that has been growing since it began in the early 2000s, combined with an expanding foreign industrial fishery that catches most of the offshore fish in the territory’s exclusive economic zone, may threaten people’s access to fresh seafood.

Industrial fisheries are starving seabirds all around the world

Industrial fisheries are starving seabirds like penguins and terns by competing for the same prey sources, new research from the French National Center for Scientific Research in Montpellier and the Sea Around Us initiative at the University of British Columbia has found.

In a study published today in Current Biology, researchers found that annual seabird food consumption decreased from 70 to 57 million tonnes between 1970 and 2010. Meanwhile, fisheries increased their catches of potential seabird prey from an average of 59 million tonnes in the 1970s and 80s to 65 million tonnes per year in recent years.
