Nereus fellow Colin Thackray (Harvard University) discusses how toxic methylmercury (MeHg) bioaccumulates within marine food webs, beginning with phytoplankton and zooplankton. This ultimately leads to some larger marine predators, such as fish, having much higher MeHg concentrations than the surrounding seawater.
Nereus colleague Jack Kittinger (Arizona State University), with Transform Aqorau and Johann Bell, respond in Science’s Policy Forum to a recent article co-authored by Nereus PI Malin Pinsky (Rutgers University). Pinksy et al. discuss how geographic shifts of migratory species due to climate change may potentially lead to conflicts over resources, while Aqorau et al. discuss examples of how good governance is working for migratory species.
Nereus fellow Fernando Gonzalez Taboada from Princeton University writes about how the painting ‘And They Still Say Fish are Expensive!’ by Joaquín Sorolla is still relevant to modern fishing culture and practices, as well as different approaches to predicting future fish abundance in the ocean.
Impacts from climate change will increase the risk of extinction for vulnerable marine species, both locally and globally. But according to a new study from UBC, effective fisheries management may be able to reduce the probability of certain species going extinct by as much as 63%.
University of British Columbia researchers have found that chemical pollutant accumulation in Chinook salmon and southern resident killer whales in the Pacific Northeast Coast region will be exacerbated under climate change. This is yet another anthropogenic stressor that threatens the survivability of the both Chinook salmon and southern resident killer whales.
Nereus PI Laurie Chan and Senior Fellow Tiff-Annie Kenny attended the International Society of Exposure Science and the International Society for Environmental Epidemiology conference (ISES-ISEE 2018) in Ottawa, Canada on August 26th-30th. The conference’s focus was on environmental health concerns, and included how scientific and local knowledge combine to assess the impact of contaminated fish consumption on First Nations’ health and well-being in Canada.
Marine heatwaves can cause irreversible ecosystem damage and their frequency has doubled since 1982. If average global temperatures rise 3.5°C, we’ll see a jump from just fewer than four marine heat waves a year on average to a startling 122.
New models developed by Nereus researchers may help reduce this threat by giving regulatory agencies a powerful new tool to predict the month-by-month movements of longline fishing fleets on the high seas. The predictions should help determine where and when the boats will enter waters where by-catch risks are greatest.
One hundred and twenty five nations gathered from July 9-13 at the Committee on Fisheries meeting at the Food and Agriculture Organization headquarters in Rome, Italy, to examine international fisheries and agriculture issues.
In a Q & A session with Nereus researcher Dr. Richard Caddell, we delve deeper into the policy implications of the projected mass migration of fish towards the poles.
Halibut, sole and other flatfish are household names around the world. But that might not always be the case. New paper finds that climate change will drastically reduce flatfish numbers and alter species distributions by hundreds of kilometers by the end of the century.
The Nassau grouper: an endangered, boldly striped fish that was once plentiful in southern coastal Florida, the Florida Keys, Bermuda, the Yucatan, and the Caribbean Sea. For more than 20 years, conservationists in the Caribbean have been working to protect this endangered species. Climate change now threatens to undo all of it.
Twenty six million tons of seafood, worth $23 billion is illegally caught, unregulated and unreported every year. According to the UN Food and Agricultural Organization, this is a “huge threat to all efforts to bolster sustainable fishing in the world’s oceans.”
The United Nations’ Sustainable Development Goals are an admirable set of targets set out to achieve a better world–but how do they interact with each other? Are some more pivotal to the success of all? Possibly.
All the big names in the field were in attendance; the 5 days of presentations crystallized how far we have come in understanding what climate change will mean for ocean systems. But we still have a long way to go before we achieve climate-ready ocean resource management.
I think what inspires me most about this group is that it values a diverse array of approaches to research. We reward the type of disciplinary flexibility and freedom that most academic organizations tend to smother. Nereus lets us be who we want to be, not who they want us to be
As coastal and surface fisheries are depleted and fishers turn to the deep sea to fill their nets, scientists are developing innovative ways to locate and protect undiscovered deep-sea habitats.
The most prevalent seafood supply chain is the shortest one: from the ocean to the plate. And that’s the one we have the least information on. Small-scale fisheries are vital to coastal communities around the world, but their contributions to global harvests are severely underestimated.
What happens to big prey when you fish out all of their big predators? Nereus researchers dig deeper into size-specific diet shifts.
Behind the scenes with a determined group of human rights and fisheries experts working to bring social responsibility to the forefront of sustainable fishing.
Reducing tourist consumption of reef fish is critical for Palau’s ocean sustainability, finds a new Nippon Foundation-UBC Nereus Program study published today in Marine Policy.
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.
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.
Nereus Fellow, Rachel Seary, a PhD Student at the University of Cambridge and the United Nations Environment World Conservation Monitoring Centre, has just returned from Cambodia, where she conducted a month long fieldwork period aimed at understanding the links between mangroves and fishing community livelihoods.
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.
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.
Pacific bluefin tuna are in trouble — they’re at just 2.6% of historic, pre-fishing levels. They have been overfished and this overfishing is still continuing. Due to this dire situation, proper management of the stocks is increasingly important, yet information of the fish’s life history and migration patterns is limited.
Developing nations, which have contributed little to the issue of climate change, are likely to experience reduced livelihood opportunities and emerging dietary nutrient deficiencies as a result of climate change impacts on fisheries.

Indigenous seafood consumption study featured in the Washington Post, CBC, and Metro News.
Traditionally, Indigenous people have resisted research, especially quantitative research that has fed into the imposition of discriminatory socio-economic and political policies to the detriment of Indigenous communities. However, having access to a global database that quantifies fish consumption specifically by Coastal Indigenous peoples around the world, is a critical contribution to Indigenous struggle on a number of fronts.

Aquaculture, the farming of aquatic species, is gradually becoming an important aspect of solving the challenge of global food security. The supply of seafood from fisheries is declining; fish stocks can only be increased if we reduce our fishing pressures, yet governments continue to subsidize the fishing industry for us to fish more. Hence, the open window we have is aquaculture.
n the lead up to last week’s referendum on whether the United Kingdom should remain in the European Union, immigration often seemed to be at the forefront at the debate. But the fishing industry was also a hot topic, even leading to demonstrations and bitter exchanges on the impact of EU membership, including from boats on the Thames.

The Nereus Program presented at the Global Fishing Watch Research Workshop on June 6th and 7th at Google’s offices in San Francisco, California, United States.
Fish don’t respect borders. With 1982’s United Nations Convention on the Law of the Sea, coastal nations were given the right to manage fisheries within their Exclusive Economic Zones (EEZ) – the area that extends, generally, up to 200 nautical miles. But of course, fish don’t adhere to imaginary lines in the ocean.
Paris tends to relate to fisheries through its gourmet cuisine, which every so often includes fish. However, in December 2015, Paris was the epicenter of the renowned United Nations Climate Change Conference (COP 21), which aimed at setting a target to curb Carbon emissions at a global scale.
Japanese call it shun (?), 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).”

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.
A range of human pressures is threatening the sustainability of marine fisheries. Amongst those, overfishing, partly driven by Illegal, Unreported and Unregulated (IUU) fishing, is a major stressor. Thirty percent of global fish catch goes unreported, found a recent study by Nereus Program collaborator Sea Around Us.
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”.
While jellyfish, with their soft, gelatinous bodies, may seem like innocuous creatures, when they occur in large blooms they can often cause detrimental effects. Jellyfish blooms have been observed to clog power plants, cause mass mortality to fish in aquaculture farms, burst fishing nets and even sink a 10 tonne fishing vessel.
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.
A new Nereus Program study, funded by the Nippon Foundation, finds that dynamic ocean management, which changes in real time in response to the nature of the ocean and its users, can reduce bycatch — fish and marine species caught accidentally while catching targeted species — without additional costs to fishers.
Countries drastically underreport the number of fish caught worldwide, and the numbers obscure a significant decline in the total catch.
Nereus research reported on in the Washington Post, the Vancouver Sun, CTV News, Global News, NPR, Hakai magazine, The Tyee, Times Colonist and Vancouver Observer.
First Nations fisheries’ catch could decline by nearly 50 per cent by 2050, according to a new study examining the threat of climate change to the food and economic security of indigenous communities along coastal British Columbia, Canada.
Based on the current trajectory of human-induced impacts on the environment, it is clear that we are pushing the oceans and marine ecosystems to unprecedented limits.
Climate change could affect temperatures all over the world, but what may not be immediately apparent is that climate change will affect ocean temperatures.

In A Sand County Almanac, the landmark book on wilderness, ecology, and conservation, we are offered a short anecdote regarding a changing environment:
“I had a bird dog named Gus. When Gus couldn’t find pheasants he worked up an enthusiasm for Sora rails and meadowlarks. This whipped-up zeal for unsatisfactory substitutes masked his failure to find the real thing. It assuaged his inner frustration.” – Aldo Leopold (1949).
