Western & Central Pacific Fisheries Commission (WCPFC) Meeting — Managing tropical tunas

The Western & Central Pacific Fisheries Commission (WCPFC) held an Intercessional Meeting, from August 22 to 24 2017 in Honolulu, Hawaii, for negotiations for the conservation and management of highly migratory fish stocks. Nereus Principal Investigator Quentin Hanich (University of Wollongong) was in attendance with new Nereus Fellow Katy Seto, who joined the Nereus network in September 2017 after completing her doctoral degree at University of California at Berkeley.

How polluted your tuna is depends on where it comes from

By Colin Thackray, Nereus Fellow at Harvard University

It’s fairly common knowledge that tuna is high in methylmercury, a neurotoxin that bioaccumulates in marine food webs. This means that methylmercury magnifies further up the food web – tuna eat smaller fish that eat even smaller fish or plankton — all of which could contain the contaminant.

“Our energy choices have ramifications for many other types of pollutants,” said Elsie Sunderland, Associate Professor of Environmental Science and Engineering at Harvard University and Nereus Program collaborator. “Hydroelectric: when we flood our reservoirs we actually cause a dramatic pulse in methylmercury production, which is neurotoxic, and we also cause a pulse in CO2 and methane.”

Investigating ideal fishing conditions for tuna and swordfish in the U.S. northwest Atlantic ocean

Recently published in Fisheries Oceanography by Nereus Alumnus Andre Boustany (Duke University) and Principal Investigator Patrick Halpin (Duke University) was the study “Tuna and swordfish catch in the U.S. northwest Atlantic longline fishery in relation to mesoscale eddies”. This research looks at the effects of different variables on the catch of tuna and swordfish — including mesoscale eddies, which are a type of ocean current, sea surface temperature and fishing gear used.

The status and future of bluefin tunas in our global ocean: The Bluefin Futures Symposium

by Guillermo Ortuño Crespo

For three days from January 18th to 20th, Monterey, California, has become an aggregation hotspot for more than 100 of the world’s foremost experts on the conservation and management of the three bluefin tuna species that inhabit our global ocean. The Bluefin Futures Symposium represents the first-ever international gathering of leading science, policy, industry and conservation leaders to address the current stock status, research efforts and management uncertainties, topics which hold the key to ensuring the future sustainability of harvesting these ocean predators.
