Castelhano-Carlos, M. J., Baumans, V. 2009. The impact of light, noise, cage cleaning and in-house transport on welfare and stress of laboratory rats. Laboratory Animals 43(4), 311-327.

Human interaction and physical environmental factors are part of the stimuli presented to laboratory animals everyday, influencing their behaviour and physiology and contributing to their welfare. Certain environmental conditions and routine procedures in the animal...

Zhu, J., Shi, W., Zhao, R. et al. 2024. Effects of cold stress on the hemolymph of the Pacific white shrimp Penaeus vannamei. Fishes 9(1), 36.

Temperature is an important factor in the physiological processes of aquatic organisms and can seriously affect several chemical and biological processes in their bodies, including respiratory metabolism, antioxidant capacity, immune capacity, and signal transduction. In...

Spitzer, H. B., Meagher, R. K., O’Sullivan, M. L. et al. 2024. The effect of a hiding space on the behaviour and heart rate variability of dairy calves during temporary separation from the dam. Animal Welfare 33, e2.

In natural settings, newborn calves hide for several days before joining the herd. It is unclear whether dairy calves housed indoors would show similar hiding behaviour. This study aimed to describe the use of an...

Savel, S., Legou, T. 2024. The dog soundscape: Recurrence, emotional impact, acoustics, and implications for dog observations and dog–human interactions. Animals 14(2), 279.

While numerous dog behavioral studies use environmental sounds, the dog soundscape remains undescribed. We proposed a list of 79 sounds classified into six categories: Dog, Dog accessories, Human, city and vehicles, Garden, countryside and weather...

Papadopoulos, D. K., Lattos, A., Chatzigeorgiou, I. et al. 2024. The influence of water nitrate concentration combined with elevated temperature on rainbow trout Oncorhynchus mykiss in an experimental aquaponic setup. Fishes 9(2), 74.

Intensive recirculating systems are a fast-developing sector of aquaculture. While several warm-water fish have been reared in aquaponics, almost no data are available for cold-water species. The determination of nitrate toxicity thresholds in recirculating aquaculture...

Lucas, R. J., Allen, A. E., Brainard, G. C. et al. 2024. Recommendations for measuring and standardizing light for laboratory mammals to improve welfare and reproducibility in animal research. PLOS Biology 22(3), e3002535.

Light enables vision and exerts widespread effects on physiology and behavior, including regulating circadian rhythms, sleep, hormone synthesis, affective state, and cognitive processes. Appropriate lighting in animal facilities may support welfare and ensure that animals...

Imsland, A. K. D., Methúsalemsson, H. 2024. The effects of different feed ration levels on growth, welfare rating, and early maturation in juvenile Atlantic salmon (Salmo salar). Fishes 9(2), 70.

To investigate the possible effect of different feed ration levels on the growth, welfare, and early maturation of juvenile Atlantic salmon, 450 salmon parr with a mean (±standard error) initial weight of 51.6 g (±0.8)...

Holt, R. V., Skånberg, L., Keeling, L. J. et al. 2024. Resource choice during ontogeny enhances both the short- and longer-term welfare of laying hen pullets. Scientific Reports 14(1), 3360.

We hypothesised that resource choice during early life contributes to both current and longer-term beneficial effects on animal welfare. We investigated this hypothesis in a longitudinal cross-over experiment with laying hen pullets (Gallus gallus domesticus)...

Carneiro, M. D. D., Medeiros, R. S. de, Monserrat, J. M. et al. 2024. Growth and oxidative stress of clownfish Amphiprion ocellaris reared at different salinities. Fishes 9(1), 30.

Aquaculture of ornamental marine fish is often conducted in recirculating aquaculture systems (RAS) using artificial seawater. Considering the cost of salts to produce artificial seawater (salinity 35‰), we investigated the effect of different salinities (5...

Böswald, L. F., Matzek, D., von La Roche, D. et al. 2024. Investigations on Xenopus laevis body composition and feeding behavior in a laboratory setting. Scientific Reports 14(1), 9517.

The African clawed frog, Xenopus laevis, has been used as a laboratory animal for decades in many research areas. However, there is a lack of knowledge about the nutritional physiology of this amphibian species and...
