“…In addition, the fact that cultured fish show aggressive behaviour can be put to use. For example, it has been suggested that individual levels of aggression assessed in a simple mirror test might be used to predict general stress responsiveness, and hence general suitability for culture, in Nile tilapia (Barreto et al 2009). …”

Aggression (behaviour that actually or potentially causes harm to another animal) is widespread among fishes, often taking the form of territoriality or dominance. The mechanisms that control aggression in fish are described, including the effects of stimuli from opponents, the importance of the context in which an aggressive encounter occurs and the effects of nutritional condition, endocrine status and brain biochemistry. The way aggression changes during development is then considered, evidence given for inherited differences in aggressiveness and an account presented of the environmental factors that influence the way aggression develops. The benefits that fish gain from winning fights, the costs that they incur from fighting and how they balance costs against benefits to promote their individual fitness are described. Data are then given on the incidence of aggression among cultured fish, on some resulting problems for production, welfare and environmental protection and on the effects of domestication and captive rearing of aggressiveness. Possible solutions to such problems are discussed, based on selecting appropriate fish for culture and the design of husbandry systems that minimise aggression. Finally, some systems for mitigating the effects of domestication and captive rearing on the aggressive behaviour of cultured fish are described.

“…This prediction contradicts the enrichment theory for welfare purposes; therefore, we tested the hypothesis that environmental enrichment increases aggression, fight duration and/or severity in an aggressive fish species when no other fight asymmetries are present. We tested this hypothesis on the cichlid Nile tilapia (Oreochromis niloticus), an aggressive fish species (Carrieri and Volpato, 1991;Barcellos et al, 1999;Barreto and Volpato, 2006a,b;Cruz and Brown, 2007;Delicio et al, 2006a; Mendonç a and Goncalves-deFreitas, 2008; Barreto et al, 2009). For this purpose, we compared fights staged between pairs of size-matched (RHP-matched) male tilapia in a novel arena that was either barren or enriched, to examine whether enrichment enhances territory value in line with theoretical predictions, with the potential for compromised welfare.…”

“…Different experimental screening methods for personality traits along a proactive-reactive continuum have being used with Nile tilapia as a model (Barreto et al 2009;Barreto & Volpato 2011;Martins, Conceição & Schrama 2011a;Martins, Conceição & Schrama 2011b;VeraCruz et al 2011), with the disadvantage of them being intensive time consuming assays. In this study we aimed to firstly assess if final thermal preferendum played a pivotal role in determining the distribution pattern of Nile tilapia with different personalities and secondly to validate final thermal preferendum as a new physiological paradigm to screen for personality traits.…”

Summary1. Environmental temperature gradients provide habitat structure in which fish orientate and individual thermal choice may reflect an essential integrated response to the environment. The use of subtle thermal gradients likely impacts upon specific physiological and behavioural processes reflected as a suite of traits described by animal personality. In this study we examine the relationship between thermal choice, animal personality and the impact of infection upon this interaction.2. We predicted that thermal choice in Nile tilapia Oreochromis niloticus reflects distinct personality traits and that under a challenge individuals exhibit differential thermal distribution.

Nile Tilapia were screened following two different protocols: 1) a suite of individual behavioural tests to screen for personality and 2) thermal choice in a custom-built tank with a thermal gradient (T CH tank) ranging from 21 to 33 ºC. A first set of fish were screened for behaviour and then thermal preference and a second set were tested in the opposite fashion; thermal then behaviour. The final thermal distribution of the fish after 48 h was assessed reflecting final thermal preferendum. Additionally, fish were then challenged using a bacterial Streptococcus iniae model infection to assess the behavioural fever response of proactive and reactive fish.4. Results showed that individuals with preference for higher temperatures were also classified as proactive with behavioural tests and reactive contemporaries chose significantly lower water temperatures. All groups exhibited behavioural fever recovering personality-specific thermal preferences after 5 days.5. Our results show that thermal preference can be used as a proxy to assess personality traits in Nile tilapia and it is a central factor to understand the adaptive meaning of animal personality within a population.Importantly, response to infection by expressing behavioural fever overrides personality related thermal choice.
