Saving Seafood

International study shows alternative seafood networks provided resiliency during pandemic

April 1, 2021 — Local alternative seafood networks (ASNs) in the United States and Canada, often considered niche segments, experienced unprecedented growth in the early months of the COVID-19 pandemic while the broader seafood system faltered, highlighting the need for greater functional diversity in supply chains, according to a new international study led by the University of Maine.

The spike in demand reflected a temporary relocalization phenomenon that can occur during periods of systemic shock—an inverse yet complementary relationship between global and local seafood systems that contributes to the resilience of regional food systems, according to the research team, which published its findings in Frontiers in Sustainable Food Systems.

The globalization of seafood has made food systems more vulnerable to systemic shocks, which can impact those dependent on seafood for sustenance and employment, according to the research team, led by Joshua Stoll, assistant professor of marine policy at the University of Maine.

Policy changes and greater investments in data collection and infrastructure are needed to support ASN development, increase functional diversity in supply chains, and bolster the resilience and sustainability of regional food systems and the global seafood trade, according to the researchers.

Canadian Government Invests in Research Assessing Impact of Oil on Pacific Salmon

December 17, 2020 — The Government of Canada announced on Tuesday $349,948 in funding will be provided to the University of Guelph for a “two-year research project to evaluate how Coho salmon, in the early stages of life, are impacted when exposed to diluted bitumen (dilbit) – a crude oil found in natural oil sands deposits that is mixed with a lighter diluent.”

The Honourable Bernadette Jordan, Minister of Fisheries, Oceans and the Canadian Coast Guard announced the funding and explained that the research builds on previous University of Guelph projects looking at impacts dilbit exposure has on salmon.

Fatty acids lower your risk of heart disease. Without fish, you’re missing out.

August 17, 2017 — Are you getting enough omega-3s? These vital fats are beneficial for heart, brain and eye health, but it’s not just the amount that matters. The type of omega-3s in your diet could determine the health benefits you’re getting — especially if you don’t eat fish.

Long-chain omega-3 fatty acids called EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are found in marine sources such as fatty fish and fish oils. Another type of omega-3s is ALA (alpha-linolenic acid), which is found in plant sources such as flax seeds, canola, chia and walnuts.

Most Americans aren’t getting enough EPA and DHA. That’s of concern because there is strong evidence that these omega-3s reduce triglyceride levels to help lower the risk for heart disease or heart attack. There is some evidence that these healthy fats may also reduce blood pressure and improve blood vessel function. And those are just some of the heart-health benefits. The evidence for these benefits in ALA isn’t as strong.

Penny Kris-Etherton, distinguished professor of nutrition at Pennsylvania State University, points out that, “We really haven’t seen evidence for benefits of plant omega-3s on cognition or in preventing stroke.”

Bruce Holub, professor at The University of Guelph adds, “EPA and DHA are shown to be quite effective at lowering triglyceride levels in the blood, while equal amounts of ALA had no effect.”

Getting enough DHA is especially important for pregnant women because it’s essential for healthy development of a baby’s brain and eyes.
