Discouraged zebrafish help reveal how ketamine works in the brain. The decades-old anaesthetic ketamine could be a game changer for treating severe depression, but there are still many questions about […]
Zebrafish testing identifies a gene potentially at the root of domestication. Researchers at Queen Mary University of London have shown that zebrafish can provide genetic baz1b clues to the evolution of social […]
Zebrafish personaility pairing improves the fitness of the species. Scientists have challenged the theory of “love at first sight” after discovering that they can boost the reproductive success of zebrafish […]
Fish farmers can influence the traits of fish through the feed. Behaviour and environmental conditions affect how genes are expressed. New research demonstrates how epigenetics may be highly relevant to […]
Women leading change in aquaculture and marine science. Follow Fish Focus’ feature on Women in the Seafood Industry, to mark this year’s International Women’s Day. Women make significant contributions to aquaculture and […]
Seeing the future: Zebrafish regenerates fully functional photoreceptor cells and restores its vision. Blinding diseases lead to permanent vision loss by damaging photoreceptor cells, which humans cannot naturally regenerate. While […]
How many fish constitute a school? Physicists are also interested in fish — above all when they are researching the formation of structures. A research team from Heinrich-Heine University Duesseldorf […]
Sleep-wake rhythm: Fish change our understanding of sleep regulation. Contrary to common belief, not all vertebrates regulate their sleep-wake rhythm in the same way. University of Basel researchers have discovered […]
Fish display distinct individual behaviours when swimming to find food. Fish from the same species can evolve their sense of smell and display individual foraging ‘personalities’ to successfully find food […]
Why fish look down when they swim. Quirky behaviour helps fish estimate swimming direction and speed, simulations show. Just as you might look down at the pavement as you walk, […]
