Spatial distribution and activity patterns as welfare indicators in response to water quality changes in European sea bass, Dicentrarchus labrax

In aquaculture, fish are exposed to unavoidable stressors that can be detrimental for their health and welfare. However, welfare in farmed fish can be difficult to assess, and, so far, no standardized test has been universally accepted as a welfare...

Aggressive encounters lead to negative affective state in fish

Animals show various behavioural, neural and physiological changes in response to losing aggressive encounters. Here, we investigated affective state, which are emotion-like processes influenced by positive or negative experiences, in a territorial fish following aggressive encounters and explore links to...

Towards more compassionate wildlife research through the 3Rs principles: Moving from invasive to noninvasive methods

Research in ecology and wildlife biology remains crucial for increasing our knowledge and improving species management and conservation in the midst of the current biodiversity crisis. However, obtaining information on population status often involves invasive sampling of a certain number...

Tilapia on-farm welfare assessment protocol for semi-intensive production systems

The aim of this study was to develop and test a tilapia on-farm welfare assessment protocol, based on Brazilian semi-intensive production systems. The study included two mains steps: the elaboration of tilapia welfare protocol and its on-field feasibility test. The...

Where the wild zebrafish are

Journeying into the field to study a model organism in its natural habitats. “Seeing them in the wild and seeing what kind of substrates they are on has really helped inform that for us, and we hope that helps inform...

Respirometer in a box: Development and use of a portable field respirometer for estimating oxygen consumption of large‐bodied fishes

Respirometry has become the standard method for measuring the metabolic rate of fishes. Traditionally, respirometry has required the fish to be kept in captivity and tested under controlled conditions; however, many species do not readily adapt to captivity, and stress...

Skin swabbing is a refined technique to collect DNA from model fish species

Model fish species such as sticklebacks and zebrafish are frequently used in studies that require DNA to be collected from live animals. This is typically achieved by fin clipping, a procedure that is simple and reliable to perform but that...

Sex segregation affects exploratory and social behaviors of zebrafish according to controlled housing conditions

Zebrafish has become an animal model in research and articles have established ideal conditions for their maintenance. However, little is known regarding the influence of gender and other cues on zebrafish behavior. Thus, here we analyzed the exploratory and social...

The effect of triploidy on the performance, gut microbiome and behaviour of juvenile Atlantic salmon (Salmo salar) raised at low temperature

Triploid Atlantic salmon (Salmo salar) aquaculture has been extensively considered for many years, but its development has so far remained very limited. This is mostly due to poorer farming performances of triploid fish (3 N) in comparison with their diploid...
