“…Although the zebrafish has long been a model for developmental research, recent work has demonstrated its suitability for both behavior and genetics research [10–14]. In particular, behavioral variation (including boldness) among individuals and populations of zebrafish is well documented [11,12,15–18]. …”

In studies of consistent individual differences (personality) along the bold-shy continuum, a pattern of behavioral correlations frequently emerges: individuals towards the bold end of the continuum are more likely to utilize risky habitat, approach potential predators, and feed under risky conditions. Here, we address the hypothesis that observed phenotypic correlations among component behaviors of the bold-shy continuum are a result of underlying genetic correlations (quantitative genetic architecture). We used a replicated three-generation pedigree of zebrafish (Danio rerio) to study three putative components of the bold-shy continuum: horizontal position, swim level, and feeding latency. We detected significant narrow-sense heritabilities as well as significant genetic and phenotypic correlations among all three behaviors, such that fish selected for swimming at the front of the tank swam closer to the observer, swam higher in the water column, and fed more quickly than fish selected for swimming at the back of the tank. Further, the lines varied in their initial open field behavior (swim level and activity level). The quantitative genetic architecture of the bold-shy continuum indicates that the multivariate behavioral phenotype characteristic of a “bold” personality type may be a result of correlated evolution via underlying genetic correlations.

Reebs 2006), which has for a long time been considered the most homogeneous social structure in fishes (Radakov 1972). Even the classical example of many ethological textbooks, the stereotypic response of male three-spined sticklebacks (Gasterosteus aculeatus) to the red belly of an opponent is very pronounced in some individuals but absent in others: it is so variable that the classical concept of innate releasing mechanisms (sign stimuli) can be questioned (Rowland 1982;Baerends 1985;Bolyard & Rowland 1996).Niko Tinbergen, in his classical work 'On the aims and methods of ethology' (Tinbergen 1963), outlined four questions that are fundamental for our understanding of any behaviour:(1) Causation: What is the cause of the behaviour in question?(2) Function: What is its survival value? (3) Ontogeny: How does it develop? (4) Evolution: How did it evolve?

“…For example, some zebrafish populations and strains have been reported to exhibit a great deal of genetic variation [18]. Previous studies have reported significant variation in different measures of zebrafish behaviours including boldness [5], predator induced behavioural responses [4], predator inspection behaviour [19], and shoaling [9, 20]. However, it has been unclear whether the observed variation was due to consistent individual differences or stochastic error variation [17].…”

Individual differences and variation in behavioural responses have been identified in many animal species. These differences may be the result of genetic or environmental factors or the interaction between them. Analysis of individual differences in behaviour may be important for many reasons. The zebrafish is a powerful model organism that is rapidly gaining popularity in behavioural brain research. However, individual differences have rarely been explored in zebrafish although significant variation in their performance has been reported. In the current study we identified individual differences in activity levels of zebrafish using a genetically heterogeneous population. Groups of zebrafish classified as high, medium, or low activity performers demonstrated consistent activity levels over a period of 7 days, and also in a subsequent open field task, suggesting stable individual differences as opposed to stochastic variation among subjects. We also uncovered a sex dependent relationship between behavioural measures. Female zebrafish in the high activity group preferred the top portion of the tank, whereas low activity females preferred the lower portion but males did not show such a relationship. The relationship between these two behaviours in females implies the potential existence of a behavioural syndrome persisting between contexts. Furthermore, females demonstrated a higher level of consistency in their behaviour as compared to males, and the behavioural differences were found to be independent of both body size and weight of the tested subjects. The identification of individual differences in activity levels in zebrafish will allow the investigation of underlying genetic and/or environmental underpinnings.
