Conservation of endangered galaxiid fishes in the Falkland Islands requires urgent action on invasive brown trout

The paper assesses the impact of invasive brown trout on native galaxiid fishes in the Falkland Islands, finding high establishment success and predicting near-complete invasion within 70 years.

Personality profiling may help select better cleaner fish for sea-lice control in salmon farming

This study identifies personality traits in lumpfish that correlate with their effectiveness as cleaner fish, suggesting optimal personality profiles for improving sea-lice control in salmon farming.

Additive and non-additive epigenetic signatures of hybridisation between fish species with different mating systems

The paper examines epigenetic signatures in hybrids of two mangrove killifish species with different mating systems, finding additive and non-additive methylation patterns and their potential role in evolutionary diversification.

More than meets the eye: syntopic and morphologically similar mangrove killifish species show different mating systems and patterns of genetic structure along the Brazilian coast

This study compares the genetic structure and mating systems of two syntopic mangrove killifish species along the Brazilian coast, finding that outcrossing K. ocellatus shows stronger population subdivision than selfing K. hermaphroditus.

Early life stress causes persistent impacts on the microbiome of Atlantic salmon

This study examines how early life stress affects the microbiome of Atlantic salmon fry, finding that both acute and chronic stressors alter gut and skin microbial communities, promoting pathogenic bacteria and reducing beneficial taxa.

Rapid quantitative assessment of fish larvae community composition using metabarcoding

This study evaluates the quantitative accuracy of DNA metabarcoding for assessing fish larvae community composition compared to morphological identification, finding strong correlations and reliable abundance estimates.

Cortisol-induced signatures of stress in the fish microbiome

This study shows that stress-induced cortisol in Atlantic salmon affects faecal microbiome diversity and structure, while skin-mucus cortisol does not impact the skin microbiome.

Seasonal and spatial variation in growth and abundance of zebra mussel (Dreissena polymorpha) in a recently invaded lake: implications for management

This study examines seasonal and spatial variations in zebra mussel growth and abundance in a UK lake, identifying density-dependent mechanisms and suggesting management strategies.

Predator recognition and anti-predatory behaviour in a recent aquatic invader, the killer shrimp (Dikerogammarus villosus)

The study examines predator recognition and anti-predatory behavior in killer shrimp exposed to fish kairomones, finding increased hiding time but no change in aggregation behavior.

Experimental evidence of invasion facilitation in the zebra mussel-killer shrimp system

The paper tests if zebra mussels facilitate killer shrimp establishment through substrate and chemical cues, finding attraction to mussel substrates and scents but no learned behavior.

Trophic plasticity of the highly invasive topmouth gudgeon (Pseudorasbora parva) inferred from stable isotope analysis

This study uses stable isotope analysis to examine the trophic plasticity of the invasive topmouth gudgeon in different aquatic systems, finding significant variation in diet and trophic position.

Local parasite pressures and host genotype may modulate epigenetic diversity in a mixed-mating fish

The paper examines how parasite pressures and host genotype affect DNA methylation diversity in a self-fertilizing fish, finding that parasites have a stronger local influence on methylation than inbreeding.

Chemical degumming increases larvae size and facilitates commercial production of Lumpfish (Cyclopterus lumpus) eggs

This study tests chemical degumming with alcalase on lumpfish eggs, finding it increases larvae size and hatching success without harming embryos, supporting its use in aquaculture.

Environmental plasticity and colonisation history in the Atlantic salmon microbiome: a translocation experiment

This study investigates microbiome plasticity and historical colonization effects in Atlantic salmon by translocating fry to different environments, finding significant environmental influence over microbiome structure and some historical effects.

Fear contagion in zebrafish: a behaviour affected by familiarity

This study shows that zebrafish exhibit fear contagion, with familiarity enhancing the transmission of fear through observational learning.

Monitoring the eradication of the highly invasive topmouth gudgeon (Pseudorasbora parva) using a novel eDNA assay

The paper evaluates the effectiveness of a novel eDNA-qPCR assay in monitoring the eradication of topmouth gudgeon in treated ponds.

Density-dependent changes in neophobia and stress-coping styles in the worlds oldest farmed fish

This study examines how density affects neophobia and stress-coping styles in farmed Nile tilapia, finding that high density increases fear and stress while reducing aggression.

Inter-population variation in the Atlantic salmon microbiome reflects environmental and genetic diversity

This study examines microbiome variation in Atlantic salmon populations, finding that genetic and environmental factors shape microbial diversity and structure in skin and gut.
