Tales from the Sea: Building relationships between scientists and fishers

As part of the 2016 International Marine Conservation Congress, in St John’s, Newfoundland, new Nereus Fellow at Stanford Julia Mason shared her story about beginning her career in science and the realizations she had. She discusses the disconnect between fisheries science and the management of the fisheries on the ground and the importance of building relationships.

Who is eating who? How climate change is modifying predator prey interactions

Climate change is expected to have many impacts on the oceans; one of them is where fish are located in the ocean. Ocean warming is expected to cause fish to shift to different locations that are cooler — generally toward the poles and into deeper waters. But not all fish are moving in the same directions and at the same speeds. This is changing what fish are eating and who are eating them.

Developing countries face decreases in both fisheries and agriculture production under climate change

The authors looked at how food production on land and in the sea will be threatened by climate change and what the future effects on biodiversity, livelihoods and food security will be. They adopted the human development index (HDI) — a global index of life expectancy, education and per capita income. They found that all of the low human development index countries will face declines in both agriculture and fisheries production by 2050.

Global change in the trophic functioning of marine food webs

The rapid development of fisheries in the 1950’s facilitated declines in predator biomass, overexploitation, collapse of fish stocks, and degradation of marine habitats. A new PLOS ONE paper investigates past changes in trophic functioning of marine ecosystems cause by human-induced changes in species assemblages by applying an ecosystem approach to fisheries.

One small bay in Japan has been attracting marine scientists from around the world for more than 100 years

By Robert Blasiak, Nereus Program Fellow at Stockholm University

Let’s turn the clock back 113 years. The prominent German zoologist Franz Doflein is about to embark on a two-year journey with the dream of becoming one of the first scientists to study the marine flora and fauna of the deep-sea trenches off the coast of Japan. Reports that the Japanese and Russian empires have just declared war on each other are troubling, yet months of preparation cannot be abandoned, and in the summer of 1904, he boards the Prince Heinrich, a steamship bound for East Asia.
