“…Male dominance in some lizard species also appears to be influenced by locomotor function, with enhanced locomotor performance increasing the likelihood of territorial dominance (Garland et al 1990;Perry et al 2004;Robson and Miles 2000). Metabolic rate similarly appears to be related to social dominance in fish (Metcalfe et al 1995;Priede 1985;Yamamoto et al 1998). Rather than disparate views, we suspect that these two perspectives, behaviorally proactive and enhanced metabolic and/or locomotor performance, may both be influenced by similar neural and endocrine machinery (Emerson et al 2000;Waters et al 2005).…”

Future social rank: forecasting status in the green anole (Anolis carolinensis)

Predicting the future social standing of an individual without aggressive social interaction may seem contradictory, as formation of social rank depends on agonistic interactions. In the lizard Anolis carolinensis, predicting social rank is possible using latency to eyespot formation (sympathetic darkening of postorbital skin from green to black during stressful agonistic interactions), because they form more rapidly in male lizards that become dominant. Darkened eyespots also inhibit aggressive behavior. As the timing of eyespot formation appears to be an important component of stress responsiveness and future social status, we hypothesized that a proactive disposition toward non-aggressive behavior, such as feeding and courtship, would be associated with aggressiveness. We assessed the relationship between rank and the temporal dynamics of eyespot formation, latencies to aggressive display, feeding, and reproductive behavior. Male lizards that became dominant were faster to respond to all types of stimuli tested (aggression, feeding, and courtship). The temporal dynamics of the neuroendocrine stress response appear to influence the motivation for behavioral response. Animals that recover from stress more quickly also eat, court, and fight more readily. In summary, this work suggests that latencies to aggressive, reproductive, and feeding behavior, as well as eyespot signals, are reliable predictors of future social status of individual male A. carolinensis.

“…Early studies found a correlation between otolith growth and temperature (Mosegaard et al 1988), which indicated a relationship between fish metabolism and otolith growth. This idea was substantiated by studies finding a correlation between standard or resting metabolic rate and otolith growth (Wright 1991;Yamamoto et al 1998;Neat et al 2008). However, Wright et al (2001) did not find a simple proportionality between resting metabolic rate and otolith growth, suggesting that additional factors are important.…”

“…Studies examining the relationship between otolith increment widths and metabolic rates eventually led to the conclusion that the proportionality observed in most studies was due to a common dependence on metabolic processes Yamamoto et al 1998;Armstrong et al 2004;Bang and Grønkjaer 2005). In short, processes related to the metabolism of fish govern both fish and otolith growth and give rise to the observed proportionality of otolith and fish size.…”

“…The possibility of using otolith growth and size as an indicator of physiological performance was introduced by Mosegaard (1990) and further developed by, among others, Titus and Mosegaard (1991), Metcalfe et al (1992) and Yamamoto et al (1998). These works linked life history traits such as growth potential and dominance status in salmonids to the size of their otoliths at emergence.…”

Abstract. Otoliths are remarkable recorders that store visual and chemical information that can be interpreted with regard to individual fish phenotype trajectory, life history events and environment. However, the information stored in the otoliths must be interpreted with the knowledge that the otolith is an integral part of fish sensory systems. This means that the environmental signals recorded in the otoliths will be regulated by the homeostatic apparatus of the individual fish -its physiology and ultimately its genetic make-up. Although this may complicate interpretation of environmental signals, it also opens up avenues for new research into the physiology and life history of individual fish. This review focuses on research areas where the coupling between otolith characteristics and fish physiology may yield new insights. Most of the research ideas are by no means new, but rather represent largely forgotten or less-explored research areas. Examples of questions that are fundamental, unanswered and with the potential to yield significant new insights are those related to the coupling of otolith and fish growth through metabolism, and the formation of opaque and translucent growth zones in relation to the physiology of the individual. An integration of visual and chemical data with bioenergetic modelling may yield some of the answers.

“…In fights between pairs of size-matched, first-feeding Atlantic salmon (Metcalfe et al 1995) and rainbow trout (McCarthy 2001), the individual with the higher resting metabolic rate is most likely to win. In juvenile masu salmon (Oncorchynchus masou) there is a significant positive relationship between resting metabolic rate and the ability of fish to monopolise large profitable territories (Yamamoto et al 1998). Compared to subordinates, dominant juvenile Arctic charr, which have high resting metabolic rates, also have higher activity of enzymes involved in respiratory metabolism in their muscles (Le Francois et al 2005).…”

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.
