“…Although more and more criticized, stereotypies are often considered as unnatural and indicative of frustration in vertebrates with an increase in the number of stereotypies translating a decrease in welfare343738. Similarly, a high aggressive behaviour often leads to altered fish welfare with negative consequences like fin damages, impaired immune functions or decrease in food intake and increased energy expenditure3940. As such, the observed reduction of aggressive behaviour and stereotypies by the plant-based diet would thus reflect improved welfare compared to the classical marine diet.…”

The composition of feed for farmed salmonids has strongly evolved during the last decades due to the substitution of fishery-derived fish oil and fishmeal by ingredients of plant origin. Little information is available regarding the effects of this transition on adaptive capacities in fish. Two rainbow trout isogenic lines, known for their divergent ability to grow on a plant-based diet (PBD), were fed for seven months from first feeding either a fully PBD or a control marine-resources diet and were compared for their growing and survival capacities over time and their behavioral and stress responses at similar sizes but different ages. Although fish displayed similar appetitive behaviour, the two lines were highly affected by the PBD translated in decreased growth and apathetic behaviour, but also stronger stress responses displayed by stronger cortisol increases and more stress-related behaviour when isolated. The two lines were found to be similarly sensitive to a PBD for the assessed stress-related parameters, but one line displayed a lower survival during the early rearing period. Overall, these results suggest that a PBD supplied to fish from the alevin stage has strong effects on physiological and behavioural parameters, with possible impairment of fish welfare, but also genome-dependent survival.

“…Centrality measures the quantity of direct connections an individual has with others within the network (Wasserman & Faust, 1994). Because aggressive interactions could be usually non-symmetrical, in-degree centrality (amount of aggression received) and out-degree centrality (amount of aggression generated) were calculated for each fish (Cañon Jones et al, 2010). Because aggressive interactions could be usually non-symmetrical, in-degree centrality (amount of aggression received) and out-degree centrality (amount of aggression generated) were calculated for each fish (Cañon Jones et al, 2010).…”

“…Cañon Jones et al (2010) examined how feed restriction of Atlantic salmon affected social structure and the occurrence of fin biting. Feed restricted groups of fish were found to form denser affiliative and aggressive networks, indicating that the individuals in these groups interacted with more of their group members than in non-restricted groups.…”

“…The utility of social network analysis for assessing the heterogeneity of social environments experienced by individual group members and for identifying individuals who may play especially important social roles, for example in maintaining group stability (Flack et al, 2005; McCowan et al, 2008; Beisner et al, 2011a,b; McCowan et al, 2011), has also been emphasized. Interestingly, despite suggestions that the social network approach could be used to provide new insights with respect to animal management and welfare issues (Krause et al, 2007), few such studies have been conducted (but see Durell et al, 2004; Webb, 2005; McCowan et al, 2008; Böhm et al, 2009; Cañon Jones et al, 2010; Beisner et al, 2011a,b; McCowan et al, 2011). …”

Social network analysis is increasingly used by behavioral ecologists and primatologists to describe the patterns and quality of interactions among individuals. We provide an overview of this methodology, with examples illustrating how it can be used to study social behavior in applied contexts. Like most kinds of social interaction analyses, social network analysis provides information about direct relationships (e.g. dominant–subordinate relationships). However, it also generates a more global model of social organization that determines how individual patterns of social interaction relate to individual and group characteristics. A particular strength of this approach is that it provides standardized mathematical methods for calculating metrics of sociality across levels of social organization, from the population and group levels to the individual level. At the group level these metrics can be used to track changes in social network structures over time, evaluate the effect of the environment on social network structure, or compare social structures across groups, populations or species. At the individual level, the metrics allow quantification of the heterogeneity of social experience within groups and identification of individuals who may play especially important roles in maintaining social stability or information flow throughout the network.
