The Nereus Program will support the “Strengthening International Fisheries Law in an Era of Changing Oceans” workshop on February 7 and 8, 2017. The event will be held by the…
From tiny phytoplankton to massive tuna: how climate change will affect energy flows in ocean ecosystems
Phytoplankton are the foundation of ocean life, providing the energy that supports nearly all marine species. Levels of phytoplankton in an ocean area may seem like a good predictor for the amount of fish that can be caught there, but a new study by Nereus Program researchers finds that this relationship is not so straightforward
Meeting the Paris Agreement global warming target of 1.5°C will have large benefits to fisheries, finds a new Nippon Foundation-Nereus Program study published in Science. For every degree Celsius decrease in global warming, potential fish catches could increase by more than three million tonnes per year.
Scenarios for investigating the future of Canada’s oceans and marine fisheries under environmental and socioeconomic change
Fisheries Economics Research Unit (UBC) Research Associate Louise Teh, Nereus Director of Science William Cheung, and OceanCanada Director and Nereus Research Associate (Honourary) Rashid Sumaila recently had a paper (“Scenarios for investigating the future of Canada’s oceans and marine fisheries under environmental and socioeconomic change“) published in Regional Environmental Change, wherein they review existing methods of scenario analysis (preparing for future response based on multiple potential outcomes) in the marine conservation and fisheries sectors in Canada.
For the past ten years, Sea Around Us has been constructing a more accurate view of world fishery catches, finding, among other things, that 30% of catch goes unreported. Now the work of 400 researchers from 273 countries, led by Daniel Pauly and Dirk Zeller, has been compiled in a comprehensive 520-page book called the Global Atlas of Marine Fisheries.
“Spatial differentiation of marine eutrophication damage indicators based on species density” was recently published in Ecological Indicators, co-authored by Nereus Alumnus Miranda Jones (UNEP-WCMC) and Nereus Director of Science William Cheung. The paper looks at developing an index to assess eutrophication effects on marine ecosystems and introducing an ecosystem response indicator to nitrogen loadings to coastal waters.
Nereus Director of Science William Cheung gave a keynote entitled “Applying macroecology to project future marine ecosystems under climate change” at the British Ecological Society’s Aquatic Macroecology Meeting in London on September 30, 2016.
This chapter explores recent and future impacts of rapid temperature changes in the North Sea, identified as a ‘hot spot’ of climate change, with respect to biological, operational, and economic concerns in fisheries. The region is one of the most important fishing grounds in the world.
