    Fish of the day: Why does seafood seasonality matter?

    By Wilf Swartz, Nereus Program Manager/Research Associate

    Japanese call it shun (旬), the seasonality of food. It refers to the time of year when a specific type of food is at its peak, either in terms of harvest or flavour. It is not unique to Japanese culture, as The Byrds reminded us in the mid-1960s with their, now classic, rendition of “Turn! Turn! Turn! (to Everything There Is a Season).”

    Ask an Expert: Why is the global fishing industry given $35 billion in subsidies each year?

    OceanCanada Research Director Rashid Sumaila and his collaborators from the UBC Global Fisheries Cluster (Sea Around Us and the Nereus Program) have published an updated estimate of global fisheries subsidies in the international journal Marine Policy. The researchers found that the global fishing industry is being supported by $35 billion yearly in government subsidies, the majority of these, upwards of $20 billion annually, promote increased capacity that can lead to harmful impacts such as overfishing.

    Where do we go from here? Building confidence in climate change impact projection models

    Climate change is expected to have major impacts on the ocean, the species that live there, and the people who rely it for their food and livelihood. Since the beginning of the 20th century, CO2 emissions from human activities have altered physical and chemical properties of the ocean. The ocean has become warmer and, in some areas, less oxygenated, which has caused changes in the productivity and distribution of marine species.
