“…The relationship between personality and cognition has been previously proven at the intraspecific level (Griffin et al 2015 ; Lucon-Xiccato and Dadda 2017a ; Daniel and Bhat 2023 ). It has been suggested that the willingness and efficiency of animals to sample environmental information might lie under the positive correlation between boldness and cognition (White et al 2017 ; Kareklas et al 2017 ; Daniel and Bhat 2023 ). In the present study, we found a positive relationship between boldness and shoal size discrimination performance across 10 selected freshwater fish species.…”

“…The link between personality and cognition may be due to the fact that proactive personalities (i.e., bold individuals) would obtain and process new information faster and hence might learn more quickly, and make decisions faster than reactive individuals (Griffin et al 2015 ; Griffin and Guez 2014 ). This has been demonstrated in fish species such as mormyrid fish ( Gnathonemus petersii ), zebrafish ( Danio rerio ) and brook trout ( Salvelinus fontinalis ) (White et al 2017 ; Kareklas et al 2017 ; Daniel and Bhat 2020 , 2023 ), as well as in reptiles (Carazo et al 2014 ), birds (Ferreira et al 2019 ) and mammals (Schuster et al 2017 ). However, all these previous studies were focused only at the inter-individual level.…”

Several studies have reported that animals’ personalities are often correlated with individual differences in cognition. Here, we tested whether personality is related to cognition across species, focusing on 10 freshwater fishes and a task relevant for fitness, the ability to discriminate shoal size. Bolder species exhibited more ‘shuttle’ behavior for information sampling during shoal selection and showed high performance (HP) in the numerical discrimination than shyer species, i.e., low performance (LP) species. Species at both the high and low ends of sociability showed LP, possibly due to loosened selection pressure because of either no need to perform shoal size discrimination tasks frequently in nature for very high sociability species or decreased willingness and motivation to join and stay within shoals for very low sociability species. Notably, the numerical discrimination was sensitive to the numerical contrast ratio in LP species but not in HP species, suggesting that the numerical system used for size discrimination also varied between species. Overall, we demonstrated the interspecies relationship between personality and shoal size discrimination across fish species, suggesting an evolutionary link between numerical abilities and behavior.

“…It has been hypothesized that covariations with personality might help maintain cognitive variation [28]. Additionally, these covariations might result from local adaptation to ecological conditions, as suggested by different patterns shown by populations from distinct habitats [29,30]. Considering that similar relationships between traits are affected by environmental stressors [31,32], it is important to consider the covariation between cognition and behaviour to fully understand the potential impact of ALAN.…”

Embryonic exposure to artificial light at night impairs learning abilities and their covariance with behavioural traits in teleost fish

The natural light cycle has profound effects on animals' cognitive systems. Its alteration owing to human activities, such as artificial light at night (ALAN), affects the biodiversity of mammalian and avian species by impairing their cognitive functions. The impact of ALAN on cognition, however, has not been investigated in aquatic species, in spite of the common occurrence of this pollution along water bodies. We exposed eggs of a teleost fish (the zebrafish Danio rerio ) to ALAN and, upon hatching, we measured larvae’ cognitive abilities with a habituation learning paradigm. Both control and ALAN-exposed larvae showed habituation learning, but the latter learned significantly slower, suggesting that under ALAN conditions, fish require many more events to acquire ecologically relevant information. We also found that individuals' learning performance significantly covaried with two behavioural traits in the control zebrafish, but ALAN disrupted one of these relationships. Additionally, ALAN resulted in an average increase in larval activity. Our results showed that both fish's cognitive abilities and related individual differences are negatively impacted by light pollution, even after a short exposure in the embryonic stage.

Changes in group behaviour in response to a preferred environment reflect positive affect

When observed in their preferred environments, animals display behavioural changes, such as an increase in resting or a reduction in agonism, suggestive of positive affect and improved welfare. However, most studies focus on the behaviour of individuals or, at most, pairs of animals; even though in group-living animals beneficial environmental changes may impact on how the group behaves as a whole. In this study, we investigated whether experiencing a preferred visual environment affected the shoaling behaviour of zebrafish (Danio rerio) groups. We first confirmed a group preference for an image of gravel placed underneath the base of a tank compared to a plain white image. Second, we observed replicated groups either with or without the preferred (gravel) image present to determine if a visually enriched and preferred environment could elicit changes in shoaling behaviour. We found a significant interaction between the observation time and test condition, with differences in shoaling behaviour reflective of increased relaxation emerging gradually over time in the gravel condition. The findings of this study reveal that experiencing a preferred environment can alter group behaviour, making such holistic changes valuable as potential indicators of positive welfare.
