Stocking Density

Time-budget of horses reared for meat production: Influence of stocking density on behavioural activities and subsequent welfare

Horses reared for meat production can be kept in intensive breeding farms where they are housed in group pens at high stocking densities. The present study aimed to evaluate whether the expressed behaviours correlated with stocking density, and to compare...

A scoping review: The impact of housing systems and environmental features on beef cattle welfare

Housing systems and environmental features can influence beef cattle welfare. To date, little information has been synthesized on this topic. The aim of this scoping review was to examine the relationship between housing and welfare status, so that beef cattle...

Conspecific density and environmental complexity impact behaviour of turquoise killifish (Nothobranchius furzeri)

Fish models are essential for research in many biological and medical disciplines. With a typical lifespan of only 6 months, the turquoise killifish (Nothobranchius furzeri) was recently established as a time- and cost-efficient model to facilitate whole-life and multigenerational studies...

Social dynamics and behavior of zoo-housed red-footed tortoises at different housing densities

Within zoos, it is common for animals that are considered solitary to be housed with conspecifics. This may be due to a variety of factors such as spatial constraints within zoos, difficulties associated with transferring animals, breeding goals, and/or other...

Editorial: Fish welfare in aquaculture and research—where are we going?

Rapid technical developments are taking place in aquaculture, and its production is increasing globally every year by more than 4%. Research is the necessary foundation for politics to define reasonable regulations and recommend guidelines for aquaculture, but also the basis...

Assessing the welfare of spiny lobsters and true lobsters in aquaria: Biology-informed best-practice guidelines for captive conditions

The welfare of decapod crustaceans held in captivity, whether in aquariums, holding facilities, seafood restaurants, supermarkets, or fishmongers, is attracting growing attention and concern. This review focuses on three species that are commonly found in European commercial environments: the European...

Personality traits of the territorial crustacean Chinese mitten crab (Eriocheir sinensis): Behavioral adaptations to environmental cues (2025)

Territorial crustaceans exhibit a complex set of personality traits and behavioral characteristics that are critical for their survival, growth, and overall welfare. This study aimed to systematically investigate the interplay between two essential personality traits—boldness and aggression—in Chinese mitten crabs...

The welfare of farmed Nile tilapia: A review (2025)

Nile tilapia are, by absolute number of individuals, the most farmed species of fish today, yet we know little about how common husbandry practices impact their welfare. Despite their global importance, there is a notable lack of detailed, species-specific welfare...

Effects of housing density on anxiety-like behavior of zebrafish in the plus maze with ramp

Population density in experimental animals is a crucial factor in maintaining the wellbeing of the organisms. Inadequate housing conditions can compromise the validity and reliability of research results, making comparisons between studies difficult. In sociable species such as zebrafish (Danio...

Husbandry protocols for juvenile loggerhead sea turtles (Caretta caretta) based on stress response to stocking density and dry-dock time

When necessary, sea turtles are held captive for veterinarian care and research purposes. Protocols and basic guidelines have been described for husbandry of sea turtles with veterinarian needs but not considering physiological indicators of animal welfare. Because all sea turtle...
