New report: Improving the welfare of cultured low-trophic aquaculture species in a changing climate

New report: Improving the welfare of cultured low-trophic aquaculture species in a changing climate The farming of low-trophic species, mainly filter feeders, is sustainable but sensitive to climate change as the species cannot regulate temperature and salinity. A risk assessment for Västra Götaland identified 22 current and an equal number of future climate-related welfare risks, including extreme temperatures and changes in food availability. Four...

New article: Integrating biodiversity impacts into seafood life cycle assessments: pathways for improvement

New article: Integrating biodiversity impacts into seafood life cycle assessments: pathways for improvement The researchers identified 39 environmental impacts linked to seafood production, 90% of which cause biodiversity loss. In previous life cycle assessments, only one-fifth of these had been included, despite the fact that methodologies exist for half of the impacts. The most serious limitations in previous...

New article: Aquaculture potential of Atlantic wolffish (Anarhichas lupus): stress and physiological responses to acute handling

New article: Aquaculture potential of Atlantic wolffish (Anarhichas lupus): stress and physiological responses to acute handling Wolffish could be farmed in Nordic aquaculture, but there is a lack of knowledge about how the fish would fare in such an environment. What is known is based on its close relative, the spotted wolffish. In this project, wolffish were exposed to...

New article: Broadly Sourced Alternative Proteins Alter Muscle Metabolome While Maintaining Sensory Quality in Rainbow Trout (Oncorhynchus mykiss)

New article: Broadly Sourced Alternative Proteins Alter Muscle Metabolome While Maintaining Sensory Quality in Rainbow Trout (Oncorhynchus mykiss) Five fish feeds that could be used as alternatives to fishmeal and soy were evaluated to see how they affect the sensory quality of fish fillets and the metabolism of fish. The alternative feeds tested were based on the fungus P. variotii, blue mussels, American...

New article: “Fish processing side streams are promising ingredients in diets for rainbow trout (Oncorhynchus mykiss) —Effects on growth physiology, appetite, and intestinal health”

New article: “Fish processing side streams are promising ingredients in diets for rainbow trout (Oncorhynchus mykiss) —Effects on growth physiology, appetite, and intestinal health” Attempts to use side streams from fish processing as feed for farmed rainbow trout showed promising results. Trimmings from sprat and mackerel in tomato sauce yielded positive results, while a diet of pickled...

New article: “Co-farming rainbow trout (Oncorhynchus mykiss) and sea lettuce (Ulva fenestrata) increased macroalgae protein content and positively affected fish welfare”

New article: “Co-farming rainbow trout (Oncorhynchus mykiss) and sea lettuce (Ulva fenestrata) increased macroalgae protein content and positively affected fish welfare” Co-farming rainbow trout and sea lettuce in the same system has a positive effect on both organisms and also improves water quality. The protein content of sea lettuce increased by 25–30% during four weeks of co-farming, and the algae contributed to a higher...

New article: Intention to buy sustainably produced fish: Planned or impulsive behavior?

New article: Intention to buy sustainably produced fish: Planned or impulsive behavior? Attitudes, subjective norms, and perceived control over one's behavior significantly predict intentions. When the factor of food engagement is added, higher engagement is shown to reinforce positive attitudes toward sustainable fish. The study also finds that impulsivity moderates the effect of social norms, where...
