The main focus of the 2017 symposium was small pelagic fisheries, which includes species such as herring, capelin, anchovy, sardine, and mackerel. Small pelagic fisheries provide about 25% of the world catch and are important for the socio-economic well-being of many coastal societies. The symposium sessions contributed to the goal of revitalizing international cooperation to develop frameworks addressing issues such as the impacts of climate and fishing pressure on small pelagic populations.
North Pacific Marine Science Organization
From November 2 to 13, the North Pacific Marine Science Organization (PICES) held their annual meeting in San Diego, USA. The meeting celebrated the 25th anniversary of PICES with the theme of looking at the past 25 years and imagining the next 25. Some of the topics of interest included coastal ecosystem stressors, loss or changes of marine biodiversity, changing productivity and species distributions in response to climate change, developing outlooks or forecasts of future ocean ecosystems, and examining climate change impacts on ocean ecosystems and human society.
Nereus Fellow at Princeton Colleen Petrik will be giving a plenary talk entitled “The Response of Fisheries Production to Natural and Anthropogenic Forcing: Past, Present and Future” at the PICES Annual Meeting in San Diego. The talk presents a mechanistic model to represent immature and mature stages of forage fishes, large pelagic fishes, and large demersal fishes, as well as preliminary of fish biomass under (1) pristine non-anthropogenic historical forcing (no anthropogenic CO2, no fishing), (2) historical climate without fishing, (3) historical climate with fishing, (4) and projected business-as-usual climate and fishing.
