“…While we do not know how younger zebrafish may react to an under-tank pebble picture, there is a chance it would be even more beneficial for young zebrafish than it is for adult zebrafish. It has also been suggested that genetically modified zebrafish may have different reactions to environmental enrichment than wildtypes [ 29 ], but more research is needed to investigate these differences.…”

Zebrafish are an established and widely used animal model, yet there is limited understanding of their welfare needs. Despite an increasing number of studies on zebrafish enrichment, in-tank environmental enrichment remains unpopular among researchers. This is due to perceived concerns over health/hygiene when it comes to introducing enrichment into the tank, although actual evidence for this is sparse. To accommodate this belief, regardless of veracity, we tested the potential benefits of enrichments presented outside the tank. Thus, we investigated the preferences and physiological stress of zebrafish with pictures of pebbles placed underneath the tank. We hypothesized that zebrafish would show a preference for enriched environments and have lower stress levels than barren housed zebrafish. In our first experiment, we housed zebrafish in a standard rack system and recorded their preference for visual access to a pebble picture, with two positive controls: visual access to conspecifics, and group housing. Using a crossover repeated-measures factorial design, we tested if the preference for visual access to pebbles was as strong as the preference for social contact. Zebrafish showed a strong preference for visual access to pebbles, equivalent to that for conspecifics. Then, in a second experiment, tank water cortisol was measured to assess chronic stress levels of zebrafish housed with or without a pebble picture under their tank, with group housing as a positive control. Cortisol levels were significantly reduced in zebrafish housed with pebble pictures, as were cortisol levels in group housed zebrafish. In fact, single housed zebrafish with pebble pictures showed the same cortisol levels as group housed zebrafish without pebble pictures. Thus, the use of an under-tank pebble picture was as beneficial as being group housed, effectively compensating for the stress of single housing. Pebble picture enrichment had an additive effect with group housing, where group housed zebrafish with pebble pictures had the lowest cortisol levels of any treatment group.

“…Research indicates that fish exhibit personality traits (known as consistency in behavior and physiology across time and context and which is characteristic of a certain group of individuals) (Castanheira et al, 2013 a; Toms & Echevarria, 2014 ). Fish researchers frequently employ a cluster of overlapping terms, including “personality traits,” “coping styles,” “behavioural syndromes,” “phenotypic expression,” “behavioural plasticity,” and “individual differences” (e.g., Buenhombre et al, 2021 ; Conrad et al, 2011 ; Demin et al, 2019 ). Currently, studies in fishes have identified personality traits such as boldness, shyness (e.g., Thorbjørnsen et al, 2021 ), exploration, avoidance, aggressiveness, locomotor activity, and sociability (e.g., Conrad et al, 2011 ; Khan & Echevarria, 2017 ; Szopa-Comley et al, 2020 ).…”

“…This article explores “emotion-like” or “affective” states, encompassing descriptors with valence (indicating positivity or negativity, reward or aversion, pleasure or displeasure, among other attributes), intensity (low or high), and duration/persistence (Paul & Mendl, 2018 ). “Affective” is often used interchangeably with “emotion” or “mood” in animal literature (Kremer et al, 2020 ) across various species, including mammals (e.g., Mendl & Paul, 2020 ), birds (e.g., Košťál et al, 2020 ), fish (Buenhombre et al, 2021 ; Cerqueira et al, 2017 ), and invertebrates (Perry & Baciadonna, 2017 ). These states give rise to a multidimensional response that can be objectively assessed through physiological, neurological, behavioral, and cognitive indicators (Kremer et al, 2020 ).…”

“…Interventions aimed at inducing negative affective states (e.g., unpredictable housing, Harding et al, 2004 ; shaking, Bateson et al, 2011 ); chronic stress, Rygula et al, 2013 ) increase the likelihood of exhibiting negative cognitive bias (NCB) (Mendl & Paul, 2020 ), characterized by a tendency to interpret situations pessimistically (Enkel et al, 2009 ). For example, exposure to acute or chronic stressors in fish has been linked to anxiety-related behaviors (Buenhombre et al, 2021 ; Collier et al, 2017 ; Golla et al, 2020 ). Additionally, exposure to stressors (Tan, 2017 ) or non-preferred social stimuli (Laubu et al, 2019 ) has been associated with NCB.…”

Like other animals, fish have unique personalities that can affect their cognition and responses to environmental stressors. These individual personality differences are often referred to as “behavioural syndromes” or “stress coping styles” and can include personality traits such as boldness, shyness, aggression, exploration, locomotor activity, and sociability. For example, bolder or proactive fish may be more likely to take risks and present lower hypothalamo–pituitary–adrenal/interrenal axis reactivity as compared to shy or reactive individuals. Likewise, learning and memory differ between fish personalities. Reactive or shy individuals tend to have faster learning and better association recall with aversive stimuli, while proactive or bold individuals tend to learn more quickly when presented with appetitive incentives. However, the influence of personality on cognitive processes other than cognitive achievement in fish has been scarcely explored. Cognitive bias tests have been employed to investigate the interplay between emotion and cognition in both humans and animals. Fish present cognitive bias processes (CBP) in which fish’s interpretation of stimuli could be influenced by its current emotional state and open to environmental modulation. However, no study in fish has explored whether CBP, like in other species, can be interpreted as long-lasting traits and whether other individual characteristics may explain its variation. We hold the perspective that CBP could serve as a vulnerability factor for the onset, persistence, and recurrence of stress-related disorders. Therefore, studying fish’s CBP as a state or trait and its interactions with individual variations may be valuable in future efforts to enhance our understanding of anxiety and stress neurobiology in animal models and humans.

“…Non-human models, then, provide a tool for the analysis of the various genetic, environmental, or pharmacological influences underlying the behavioural expression and physiological functions homologous in non-humans and humans (Kumar, Bhat, & Kumar, 2013). Based on face, predictive, and construct validities, these models have contributed to elucidating different aspects of various psychiatric disorders, such as anxiety, depression, and PTSD (Abelaira, Réus, & Quevedo, 2013;Buenhombre, Daza-Cardona, Sousa, & Gouveia, 2021;Campos, Fogaça, Aguiar, & Guimarães, 2013;Dunsmoor, Cisler, Fonzo, Creech, & Nemeroff, 2022;Gomes Vitor de Castro et al, 2013), autism (Chadman, 2017;Varghese et al, 2017), compulsive eating (Di Segni, Patrono, Patella, Puglisi-Allegra, & Ventura, 2014;Turton, Chami, & Treasure, 2017), and schizophrenia (Jones, Watson, & Fone, 2011;Winship et al, 2018).…”

The most fundamental emotional systems that show trait control are evolutionarily old and extensively conserved. Psychology in general has benefited from non-human neuroscience and from the analytical simplicity of behaviour in those with simpler nervous systems. It has been argued that integration between personality, psychopathology, and neuroscience is particularly promising if we are to understand the neurobiology of human experience. Here, we provide some general arguments for a non-human approach being at least as productive in relation to personality, psychopathology, and their interface. Some early personality theories were directly linked to psychopathology (e.g., Eysenck, Panksepp, and Cloninger). They shared a common interest in brain systems that naturally led to the use of non-human data; behavioural, neural, and pharmacological. In Eysenck’s case, this also led to the selective breeding, at the Maudsley Institute, of emotionally reactive and non-reactive strains of rat as models of trait neuroticism or trait emotionality. Dimensional personality research and categorical approaches to clinical disorder then drifted apart from each other, from neuropsychology, and from non-human data. Recently, the conceptualizations of both healthy personality and psychopathology have moved towards a common hierarchical trait perspective. Indeed, the proposed two sets of trait dimensions appear similar and may even be eventually the same. We provide, here, an introduction to this special issue of Personality Neuroscience, where the authors provide overviews of detailed areas where non-human data inform human personality and its psychopathology or provide explicit models for translation to human neuroscience. Once all the papers in the issue have appeared, we will also provide a concluding summary of them.
