There's a carbon cost to fishmeal we use. And they're not all created equal
Back for my first post in a long while. I have recently published a paper that got some exciting news coverage. The takeaway message of the paper was that much of the fish we use for fishmeal is ‘food-grade’ fish and could thus be used for human consumption. There is a common argument that the fish...

Krill remains one of largest underexploited marine resources in the world. Krills are a group of various zooplankton that generally look like small shrimps. Krill and other zooplankton (free-floating organisms that don’t photosynthesize their own energy) float in the water column and represent a link in the food chain between primary producers (like phytoplankton) and larger animals ranging in size...

There is a multitude of different fishing gears that are used to catch fish. These gears generally vary in the scale of fishing undertaken, and are dominated by a few categories of gear. These different gear types and categories range in their impact on the ecosystem’s habitat. In addition to my work on reduction fisheries,... Continue Reading →
Most of the feed given to farmed salmon isn’t fish. In fact, fish inputs make up a smaller and smaller portion of most salmon feeds and in Norway are around 30%. While the focus of this blog is the use of fish as feed in livestock and aquaculture, it is important to consider other parts... Continue Reading →
I have a guest blog post this week on the Sea Around Us webpage on some of my recent research. Check the full post out here!
My first peer-reviewed article came out a few weeks ago and can be found here, or through my ResearchGate profile here. The article focuses on refining a measure of biotic impact as measured in life cycle assessment. Life cycle assessment attempts to quantify most environmental impacts of a product from ‘cradle-to-grave’. Thus, the greater consideration... Continue Reading →
In my last post, I discussed the largest source of fishmeal and fish oil globally, reduction fisheries (if you didn’t get a chance to read it, catch up here!). Reduction fisheries have been the primary source of fishmeal and fish oil since at least the late 1950s. In this article I’m going to give an... Continue Reading →
