Growth rates of wild stream‐dwelling Atlantic salmon correlate with activity and sex but not dominance

Abstract: Summary 1.It is generally assumed that high social status confers benefits such as increased resource acquisition and growth rate, higher survival and/or increased reproductive output relative to subordinate individuals. 2. The hypothesis that dominant juvenile Atlantic salmon would have higher growth rates than subordinates in a flow-regulated natural stream was tested. Over 2 years, seven groups of eight size-matched wild fish were tagged with passive integrated transponders (PIT tags) and assessed for domin… Show more

“…All multivariate analyses were performed in PRIMER software (Version 6.1.16, PRIMER-E Ltd, Plymouth, UK). Community abundance and taxa richness data were standardised (Z-scores) prior to further analysis (Zar, 1999;Martin-Smith & Armstrong, 2002). Functional feeding traits based on Tachet et al (2010) and abundances of taxa characterised as highly or moderately sensitive to sediment as defined by the Fine Sediment Sensitivity Ratings (FSSR given in Extence et al, 2013) were calculated for each sample.…”

“…However, in Scottish streams relative qualities of local patches in terms of food abundance vary on an hourly basis independent of water velocity, so that short-term patch quality is, to an extent, unpredictable (Martin-Smith and Armstrong, 2002). Therefore, to maximize net energy gain, salmon parr would need to be able to assess the trade-off between food density and costs of catching food at the various local current velocities available.…”

“…In the future, combined studies using biotelemetry and visual observations while snorkeling could improve the knowledge on the relation between social status and mobility in Atlantic salmon parr as well as of motivations controlling movement and space use in Atlantic salmon parr. The classical view of the mosaic distribution of territories was not confirmed; instead parr had overlapping home ranges as it has been observed elsewhere (Stradmeyer and Thorpe 1987;Armstrong et al 1999;Martin-Smith and Armstrong 2002;Økland et al 2004).…”
