“…Studies in other species, such as the eastern water skink (Eulamprus quoyii), have shown that individuals that are bolder in terms of emergence from a refuge and exploration, in general, also show better cognitive abilities (Carazo et al, 2014). Personality and cognition studies in brook trout have shown that individuals that are more aggressive in terms of food and mate monopolization are better able to perform a cognitive task, such as navigating a maze (White et al, 2017). Studies on three-spined sticklebacks have shown that boldness directly influences use of information by an individual, and bolder fish are more likely to perform better at perceiving and interpreting environmental cues (Harcourt et al, 2010).…”

Within populations, individual differences in behavioral and cognitive traits are dependent on the habitat and specific contexts, such as the presence of a predator or other risks. The ability to show variable responses to changing conditions can be of immense survival advantage to organisms. We studied individual differences in specific personality traits, such as boldness, exploration, and spatial ability, and the effect of these traits on learning ability and memory in the presence of a predatory threat, among wild caught zebrafish (Danio rerio). Under laboratory conditions, individuals were trained to perform a simple navigation task, and their performance, exploration, boldness traits were measured, along with learning and memory abilities under two contexts (i.e., in the presence and absence of a predator). Our results revealed that fish showed a clear decline in emergence time, exploration time, and feeding latency over trials, indicative of learning, and further tests for memory also showed memory retention. While the presence of a predator increased emergence time and latencies for navigating, indicating declines in boldness and exploration, these were found to be correlated to different personalities among the individuals and dependent on their sex. While females tended to be bolder and learned the spatial task faster, they showed lower memory retention abilities than males. Personality traits were also found to affect cognitive abilities among individuals. In general, the presence of a predator decreased performance latencies. However, bolder individuals were less affected and emerged more quickly from the refuge chamber than shy individuals. Our results point to the complex interplay of ecological context along with inherent correlations across personality traits that decide the overall personality and cognitive responses among individuals even within populations. These findings thus highlight the importance of an inclusive approach that combines personality and cognition studies for understanding variations within populations.

“…Individual differences in the shy-bold dimension (boldness) demonstrate the propensity of an individual to take risks and explore novelty [ 22 ]. Individuals classified as bold are considered risk prone, and are thus expected to confront new situations and expose themselves more than shy individuals [ 23 , 24 ]. Bold individuals are also less attached to the social group, less anxious and less responsive to stress when compared to their shy counterparts [ 23 ].…”

Bold individuals are also less attached to the social group, less anxious and less responsive to stress when compared to their shy counterparts [ 23 ]. Since alcohol is known to alter how one deals with the physical and social environment [ 25 – 28 ], bold and shy individuals would be expected to react differently when exposed to this drug.…”

Individual differences in response to alcohol exposure in zebrafish (Danio rerio)

Personality traits are related to many aspects of one’s life, including risk taking, sociability, and behavioral changes caused by psychoactive substances. This study aimed to investigate individual differences and behavioral changes due to alcohol exposure in zebrafish (Danio rerio). To that end, adult animals were separated into two behavioral profiles: bold and shy, according to their risk taking behavior in an emergence test. Bold and shy fish were allowed to explore a 5-chamber tank and were tested for exploration and sociability (shoaling behavior) following alcohol exposure. The acute drug exposure treatments were 0.0%, 0.1% and 0.5% (v/v%) alcohol. The behavioral parameters evaluated were average and maximum swimming speed, total distance traveled, total time spent immobile, and time spent near a shoal or exploring the tank. For the groups that received no alcohol (0.0% alcohol), shy individuals spent more time near the shoal than bold fish. However, 0.5% alcohol increased bold fish responsiveness to the shoal, while both 0.1% and 0.5% alcohol diminished shoaling in shy fish. Our results show that the behavioral profiles of zebrafish are affected differently by alcohol, with shy animals seemingly more sensitive to behavioral change due to drug exposure. Moreover, we confirm zebrafish as a model for alcohol induced functional (exploration and social behavior) changes that could be useful in high throughput drug screens.

“…According to Matsunaga and Watanabe (2010) though the relationship between boldness, exploration and habituation had been a topic of intense investigation in rodents, this line of research did not get an equal level of attention from ichthyologists. However, understanding linkage between boldness and habituation is vital since it could give insights into various cognitive phenotypes of the individual such as long term and short term memory (Leussis and Bolivar, 2006;White et al, 2017). The current result points to the need for considering and describing the properties of the apparatus being used for measuring such relationship as well as the caution to be taken while extending results obtained from studies conducted using one kind of apparatus to the others without proper investigation.…”

AbstractSwimway and open field are the two popular apparatus used for measuring boldness - the propensity to take risky decisions - in various piscine species. The present study compared boldness exhibited by an air breathing freshwater fish climbing perch in a swimway, rectangular open field, intermediate stages between these two apparatus and circular open field. Impact of the modification of the start chamber by providing substratum made up of cobbles and covering the water surface using water plant hydrilla, alone and in combinations on the boldness was also tested. Our results revealed that the apparatus has a significant impact on the boldness in climbing perch. The presence of a shelter in the experimental arena (swimway) and cobble substratum in the start chamber of the apparatus were found to be reducing boldness in this fish, while hydrilla cover on the water surface neutralised the impact of cobble substratum. Repeated exposure and resultant familiarity with the arena increased boldness of climbing perch but the pattern of modification of this behavioural trait exhibited during the course of experiment was divergent across the instruments. These results point towards the need for critically analyzing the influence of instruments used for measuring various behavioural traits and considering biological needs of the subject species while designing the apparatus.
