McMurray, C., Allen, N., Hook, S. et al. 2018. I3S software as a refinement technique to identify individuals within a captive Scyliorhinus canula population. Animal Technology and Welfare 17(3), 204-205 (IAT Congress 2018 Poster Presentation).

Demarking individual animals within a group is often required in research. However, the process of invasive tagging induces stress and if a tag becomes detached it may wound the animal and/or prevent identification. Photo identification...

Zhang, Z., Zhang, X., Li, Z. et al. 2019. Effects of different levels of environmental enrichment on the sheltering behaviors, brain development and cortisol levels of black rockfish Sebastes schlegelii. Applied Animal Behaviour Science 218, 104825.

Environmental enrichment is a promising way to increase the fitness and survival of fish released for stock enhancement and biological conservation programs. However, the effects of enrichment in different studies on the fish behavior, physiology...

Carbajal, A., Soler, P., Tallo-Parra, O. et al. 2019. Towards non-invasive methods in measuring fish welfare: The measurement of cortisol concentrations in fish skin mucus as a biomarker of habitat quality. Animals 9(11), 939.

Cortisol levels in fish skin mucus have shown to be good stress indicators in farm fish exposed to different stressors. Its applicability in free-ranging animals subject to long-term environmental stressors though remains to be explored...

Saraiva, J. L., Arechavala-Lopez, P., Castanheira, M. F. et al. 2019. A global assessment of welfare in farmed fishes: The FishEthoBase. Fishes 4(2), 30.

Fish welfare is an essential issue that needs to be tackled by the aquaculture industry. In order to address it, studies have been limited to a small number of species and the information is generally...

Fife-Cook, I., Franks, B. 2019. Positive welfare for fishes: Rationale and areas for future study. Fishes 4(2), 31.

Traditional animal welfare paradigms have focused on maintaining physical health and mitigating negative impacts to wellbeing. Recently, however, the field has increasingly recognized the importance of positive welfare (i.e., mental and physical states that exceed...

Batzina, A., Drossos, I.-P., Karakatsouli, N. 2019. Effects of familiarity on individual growth and feeding behaviour of European seabass Dicentrarchus labrax. Applied Animal Behaviour Science 211, 112-117.

Available literature indicates that fish are able to recognize familiar conspecifics and that familiarity may offer important benefits (e.g. more stable social environment, improved foraging behavior, growth, survival). In the practice of intensive rearing of...

Ellis, T., Rimmer, G. S. E., Parker, S.-J. et al. 2019. In-tank underwater cameras can refine monitoring of laboratory fish. Animal Welfare 28(2), 191-203.

Laboratory animals need to be monitored to check the status of their health and welfare. Routine checks of laboratory fish are limited to visual observations of physical appearance and behaviour, but for species held in...

Ullah, I., Zuberi, A., Khan, K. U. et al. 2017. Effects of enrichment on the development of behaviour in an endangered fish mahseer (Tor putitora). Applied Animal Behaviour Science 186, 93-100.

Structural enrichment in the rearing environment, not only promotes fish welfare, but also affects several aspects of behavioural biology of fish in aquaculture. Here an attempt was made to use physical-enrichment to improve the behaviour...

dos Santos Gauy, A. C., Pereira Boscolo, C. N., Gonçalves-de-Freitas, E. 2018. Less water renewal reduces effects on social aggression of the cichlid Pterophyllum scalare. Applied Animal Behaviour Science. 198, 121-126.

Changes in aquatic environments can affect fish behavior. Water renewal, for example, can dilute chemical signals, which are a social communication tool used by some fish species, and this dilution increases aggressive interactions in the...
