“…While the neural bases of these changes are presently unknown, environmental characteristics which lead to decision-making have been described thoroughly. For example, threat probability and distance vary in a continuum that restricts attention (Andersen et al, 2016), and therefore whether fast or slower responses are needed (Brown et al, 1999;Fanselow and Lester, 1988;Kavaliers and Choleris, 2001;Laundré et al, 2010;Mc-Naughton and Corr, 2004;Perusini and Fanselow, 2015). Thus, decision-making is biased towards escape (flight) or fight responses when the threat is proximal, while avoidance and freezing are elicited when threat is distal (Fanselow and Lester, 1988;McNaughton and Corr, 2004;Perusini and Fanselow, 2015).…”

“…In fish, defensive circuits have not been thoroughly described, but there is an increasing awareness that defensive behavior is a fundamental function in these animals (Andersen et al, 2016;Kalueff et al, 2012;Kittilsen, 2013). As a result, fish are increasingly being used in neurobehavioral research (Gerlai, 2014;Hall et al, 2014;Kalueff et al, 2014b;Stewart et al, 2015).…”

Defensive behavior is a function of specific survival circuits, the “aversive brain system”, that are thought to be conserved across vertebrates, and involve threat detection and the organization of defensive responses to reduce or eliminate threat. In mammals, these circuits involve amygdalar and hypothalamic subnuclei and midbrain circuits. The increased interest in teleost fishes as model organisms in neuroscience created a demand to understand which brain circuits are involved in defensive behavior. Telencephalic and habenular circuits represent a “forebrain circuit” for threat processing and organization of responses, being important to  mounting appropriate coping responses. Specific hypothalamic circuits organize neuroendocrine and neurovegetative outputs, but are the less well-studied in fish. A “midbrain circuit” is represented by projections to interneurons in the optic tectum which mediate fast escape responses via projections to the central gray and/or the brainstem escape network. Threatening stimuli (especially visual stimuli) can bypass the “high road” and directly activate this system, initiating escape responses. Increased attention to these circuits in an evolutionary framework is still needed.

“…For passive gears, traps catch only a proportion of fish that come within a close proximity because some fish enter traps more readily than others (Diaz Pauli, Wiech, Heino, & Utne‐Palm, ; Thomsen, Humborstad, & Furevik, ). This could depend on a number of physiological factors, including physiological traits that underlie decision‐making and risk assessment (Andersen, Jørgensen, Eliassen, & Giske, ; Giske et al., ; Höglund et al., ; Øverli, Pottinger, Carrick, Øverli, & Winberg, ; Øverli, Winberg, & Pottinger, ; Winberg & Thörnqvist, ; Table ). For passive gears, it has been suggested that decision‐making after the initial gear encounter is a greater determinant of individual vulnerability to capture than encounter rate itself (Klefoth et al., ; Monk & Arlinghaus, ).…”

There is increasing evidence that intense fishing pressure is not only depleting fish stocks but also causing evolutionary changes to fish populations. In particular, body size and fecundity in wild fish populations may be altered in response to the high and often size‐selective mortality exerted by fisheries. While these effects can have serious consequences for the viability of fish populations, there are also a range of traits not directly related to body size which could also affect susceptibility to capture by fishing gears—and therefore fisheries‐induced evolution (FIE)—but which have to date been ignored. For example, overlooked within the context of FIE is the likelihood that variation in physiological traits could make some individuals within species more vulnerable to capture. Specifically, traits related to energy balance (e.g., metabolic rate), swimming performance (e.g., aerobic scope), neuroendocrinology (e.g., stress responsiveness) and sensory physiology (e.g., visual acuity) are especially likely to influence vulnerability to capture through a variety of mechanisms. Selection on these traits could produce major shifts in the physiological traits within populations in response to fishing pressure that are yet to be considered but which could influence population resource requirements, resilience, species’ distributions and responses to environmental change.

“…The latter examples also underline the role of these circuits in regulating responses to stressful and aversive stimuli. Indeed, another layer that could be added to the overlap between SBN and the mesolimbic reward system is that of an "aversive behaviour network" (Misslin, 2003;Cezario et al, 2008;Panksepp, 2011;LeDoux, 2012a;Sternson, 2013;Canteras & Graeff, 2014;Andersen et al, 2016). This system is equivalent to the stress-anxiety-fear circuit.…”

Animal-focused research has been crucial for scientific advancement, but rodents are still taking a starring role. Starting as merely supporting evidence found in rodents, the use of fish models has slowly taken a more central role and expanded its overall contributions in areas such as social sciences, evolution, physiology and recently in translational medical research. In the neurosciences, zebrafish Danio rerio have been widely adopted, contributing to our understanding of the genetic control of brain processes and the effects of pharmacological manipulations. However, discussion continues regarding the paradox of function versus structure, when fishes and mammals are compared and on the potentially evolutionarily conserved nature of behaviour across fish species. From a behavioural standpoint, we explore aversive-stress and social behaviour in selected fish models and refer to the extensive contributions of stress and monoaminergic systems. We suggest that, in spite of marked neuroanatomical differences between fishes and mammals, stress and sociality are conserved at the behavioural and molecular levels. We also suggest that stress and sociality are mediated by monoamines in predictable and non-trivial ways and that monoamines could bridge the relationship between stress and social behaviour. To reconcile the level of divergence with the level of similarity, we need neuroanatomical, pharmacological, behavioural and ecological studies conducted in the laboratory and in nature. These areas need to add to each other to enhance our understanding of fish behaviour and ultimately how this all may lead to better model systems for translational studies.
