Corroborating age with oxygen isotope profiles in otoliths: consequences for estimation of growth, productivity and management reference points in northern pike (Esox lucius) in the southern Baltic Sea

This study validates age estimates of northern pike using oxygen isotope profiles in otoliths, showing scale-based ages underestimate true age, leading to inaccurate growth and management estimates.

Size-selective mortality fosters evolutionary changes in collective learning across ontogeny and decision-making in zebrafish, Danio rerio

This study shows size-selective harvesting in zebrafish alters learning and decision-making abilities across ontogeny, with reduced learning speed in large-harvested fish and faster decision-making in the same line.

Rhythm of relationships in a social fish over the course of a full year in the wild

This study tracks social interactions of wild common carp over a year, finding diurnal and seasonal changes in social structure driven by environmental factors.

Size-selective mortality fosters ontogenetic changes in collective risk-taking behaviour in zebrafish, Danio rerio

This study shows size-selective mortality in zebrafish alters risk-taking behavior, with small-harvested fish being bolder and large-harvested fish showing more variability in boldness across life stages.

Evolutionary impact of size-selective harvesting on shoaling behavior: Individual-level mechanisms and possible consequences for natural and fishing mortality

This study shows size-selective harvesting alters shoaling behavior in zebrafish, affecting both fishing and natural mortality through changes in vigilance and social cue use.

Data-poor stock assessment of fish stocks co-exploited by commercial and recreational fisheries: applications to pike (Esox lucius) in the western Baltic Sea

The paper applies data-poor stock assessment methods to evaluate a pike population in the western Baltic Sea, finding it fully exploited and declining due to mixed commercial and recreational fishing.

Harvesting-induced evolution of collective risk-taking behavior and changes to the circadian system in a fish

This study shows that size-selective harvesting in zebrafish alters collective risk-taking behavior and the circadian system, with behavioral changes linked to molecular circadian clock modifications.

Status of aquatic and riparian biodiversity in artificial lake ecosystems with and without management for recreational fisheries: Implications for conservation

The paper assesses biodiversity in gravel pit lakes with and without recreational fisheries management, finding no significant differences in species richness or diversity.

Saving large fish through harvest slots outperforms the classical minimum-length limit when the aim is to achieve multiple harvest and catch-related fisheries objectives

This study compares harvest slots and minimum-length limits in fisheries management, finding harvest slots better achieve multiple objectives like maximizing catch numbers and trophy fish production.

Intraspecific population admixture of a top piscivore correlates with anthropogenic alteration of freshwater ecosystems

This study examines how genetic admixture in northern pike correlates with ecosystem integrity, finding a significant positive association between genetic admixture and decreased ecological status.

Managing river fish biodiversity generates substantial economic benefits in four European countries

This study shows that managing river ecosystems for biodiversity in four European countries provides significant public economic benefits, particularly through improving abiotic attributes and restoring native fish species.

Impact of recreational fisheries management on fish biodiversity in gravel pit lakes with contrasts to unmanaged lakes

This study compares fish biodiversity in managed and unmanaged gravel pit lakes, finding higher alpha-diversity but more homogenized communities in managed lakes due to stocking.

Ecological, angler and spatial heterogeneity drive social and ecological outcomes in an integrated landscape model of freshwater recreational fisheries

The paper develops a spatial model of freshwater fisheries showing that angler population size and composition, along with spatial ecological variation, drive regional overfishing outcomes.

Spearfishing promotes a timidity syndrome and increases the safe operating distances in fish

This study shows spearfishing increases timidity in fish, leading to longer flight initiation distances and reduced catchability, with effects varying by species and protection status.
