Scottish Parliament nearing conclusion on salmon-farming sustainability inquiry
Seafood Source
Scotland’s salmon-farming industry has overcome a lot of challenges over the past few years, but more work is needed to ensure it remains sustainable and prioritizes animal health and welfare into the future, according to Scotland Cabinet Secretary for Rural Affairs, Land Reform, and Islands Mairi Gougeon.

Is Aquaculture Really Saving Fish?
American Council on Science and Health
Aquaculture, the golden child of industrial food production, promises to feed the masses while saving wild fish. While farmed fish production has skyrocketed, its efficiency can’t hide the fact that wild stocks are still overfished, and ecosystems are paying the price. Does aquaculture rescue wild fish populations – or put them at greater risk?

Aquaculture uses far more wild fish than previously estimated, study finds
Aquafeed
A study, led by an international team of scientists from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, Oceana, and New York University, suggests that global fish farming may rely on significantly larger quantities of wild-caught ocean fish than previously calculated. These findings call into question long-held assumptions about sustainability and provide a range of plausible estimates for its impact on wild fish populations.

How mariculture expansion is dewilding the ocean and its inhabitants
Science Advances
The world’s oceans are largely free from intensive farming, but momentum to intensify and expand mariculture—the cultivation of aquatic organisms in the ocean—is growing. Despite optimism that mariculture will create economic and nutritional benefits for humans, it can also generate a host of risks, including environmental degradation, harms to wildlife integrity and welfare, captivity effects, and shifts in how humans view the nonhuman world. Collectively, we refer to these four types of risks as 'dewilding.' In this systematic review, we searched Scopus and Web of Science for recent literature documenting mariculture’s dewilding impacts to organize and collate this evidence under one unified framework. We find that mariculture’s dewilding impacts are consistently documented, though often in isolation, and that captivity and conceptual dewilding impacts are recognized as potential harms far less than impacts on the environment and wildlife. Future work examining mariculture’s dewilding impacts will be paramount to guiding human decision-making and activity going forward.

A review of the global use of fishmeal and fish oil and the Fish In:Fish Out metric
Science Advances
Aquacultured carnivorous species consume most of the world’s fishmeal and fish oil (FMFO), which itself is primarily derived from small pelagic fish. This has raised concerns about the practice’s impact on wild fish stocks, ecosystems, and coastal communities that rely on these fish. The aquaculture industry claims a decreasing dependence on wild fish, relying on the Fish In:Fish Out (FIFO) metric as a ratio of the quantity of wild fish required for farmed fish production. This is misleading because it usually assumes constant FM or FO yields, inclusion rates and feed conversion ratios, which vary widely. Thus, a constant FIFO value for a given species cannot be assumed. Furthermore, low FIFO values resulting from averaging carnivores and herbivores conceal the high feed requirements of carnivore species. The increasing use of FMFO from by-products does not demonstrate a decreased use of wild fish but rather reflects a growing demand for FMFO, particularly for the fast growing and valuable salmon and shrimp farming industries.

Why aquaculture may not conserve wild fish
Science Advances
We review literature on the displacement paradox and the Jevons paradox, with consideration of their implications for the potential effects of aquaculture on wild fisheries. The Jevons paradox refers to circumstances where improvements in the efficiency of resource use lead to growth in consumption and therefore undermine conservation. The displacement paradox refers to circumstances where increasing use of a potential substitute for a resource (e.g., farmed fish) does not lead to proportionate reduction in consumption of the other resource (e.g., wild fish). The literature on the displacement paradox and the Jevons paradox suggests that there may be unanticipated consequences from the rise of aquaculture that may be detrimental for fisheries conservation. Here, we present theoretical explanations, drawing on the tragedy of the commodity, for understanding the tendencies for these technological paradoxes to occur and emphasize their relevance for concerns associated with fisheries and aquaculture systems.

Pathogens from salmon aquaculture in relation to conservation of wild Pacific salmon in Canada
Science Advances
The spread of pathogens from farmed salmon is a conservation concern for wild Pacific salmon in British Columbia (BC), Canada. Three pathogens are prevalent in farmed Atlantic salmon in BC, spill over to wild Pacific salmon, and are linked to negative impacts on wild salmon: Piscine orthoreovirus, Tenacibaculum spp., and sea lice (Lepeophtheirus salmonis). Molecular screening of infectious agents in farmed and wild salmon and environmental DNA highlights a further 4 agents that are likely elevated near salmon farms and 37 that co-occur in wild and farmed salmon. Pathogens likely affect wild salmon indirectly by mediating migration, competition, and predation. Current net-pen aquaculture practices pose these risks to numerous populations of all species of wild salmon in BC, most of which are not covered in Government of Canada science and advisory reports. Climate change, pathogen evolution, and changes to disease management and aquaculture regulations will influence future risks. By Martin Krkosek, Andrew W. Bateman, Arthur L. Bass, William S.

What to Know About the Salmon on Your Plate
NPR
Norway is the largest exporter of salmon in the world. And while some of those fish are wild-caught, many are raised in 'fish farms'- large cylindrical pens made of nylon in the open water. Sometimes these farmed fish escape, mixing with the local population and causing ecological issues. We see farmed fish in a Norwegian fjord and hear about potential solutions to the problem.

Stories of the Sea: Fishing in the Twilight Zone
Safina Center
By one estimate, it is 'the world’s largest unexploited natural resource with a global biomass of 1 gigaton.' But can the inhabitants of the deep be fished to meet humanity’s food needs? Should they be? Such questions are being asked with greater frequency, as research initiatives in multiple countries have started to explore the feasibility of mesopelagic fishing.
