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: “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...
