Changes in per capita and aggregate apparent consumption of livestock-derived foods in Canada from 1960–2020 Open
Food systems are a major driver of resource depletion and environmental degradation globally, with livestock-derived food production accounting for a disproportionate fraction of these impacts. At the same time, meat, eggs, and dairy produ…

Overwinter Changes in the Lipid Profile of Young-of-the-Year Striped Bass (Morone saxatilis) in Freshwater Ponds Open
Young-of-the-year (YOY) striped bass (Morone saxatilis) suffer significant mortality during their first winter. While causes of this mortality are unclear, lipids may play role in adapting to winter stresses, including thermal change and f…

Operating in a Climate Crisis: A State-of-the-Science Review of Life Cycle Assessment within Surgical and Anesthetic Care Open
Despite the recent proliferation of surgical and anesthesiology-related LCAs, extant studies address a miniscule fraction of the numerous services, procedures, and products available today. Methodological heterogeneity, external validity, …
View article: Potential socioeconomic impacts from ocean acidification and climate change effects on Atlantic Canadian fisheries
Potential socioeconomic impacts from ocean acidification and climate change effects on Atlantic Canadian fisheries Open
Ocean acidification is an emerging consequence of anthropogenic carbon dioxide emissions. The full extent of the biological impacts are currently not entirely defined. However, it is expected that invertebrate species that rely on the mine…
View article: 65 Sustainability of fish-derived feed inputs: an ecological perspective
65 Sustainability of fish-derived feed inputs: an ecological perspective Open
Fishmeals and fish oils (FMFOs) sourced traditionally from directed fisheries and increasingly from seafood processing by-product streams, are important sources of key nutrients in animal diets. While attention is understandably paid to th…
View article: Combined climate and nutritional performance of seafoods
Combined climate and nutritional performance of seafoods Open
National authorities in many countries advise their populations to eat more seafood, for health and sometimes for environmental purposes, but give little guidance as to what type of seafood should be consumed. The large diversity in specie…

Commentary: comparing efficiency in aquatic and terrestrial animal production systems Open
First paragraph: Aquaculture is receiving increased attention from a variety of stakeholders. This is largely due to its current role in the global food system of supplying more than half of the seafood consumed, and also because the indus…
