Pattern and variability in the breeding system of Atlantic salmon (Salmo salar), with comparisons to other salmonids

Abstract: The breeding system of Atlantic salmon (Salmo salar) is shaped both by natural selection for offspring production and by sexual selection for access to mating opportunities. These evolutionary forces operate with differing intensities in the two sexes to shape their breeding behaviour and tactics. Female breeding success is largely dependent on egg production, access to breeding territories, and nest quality and survival. By contrast, male breeding success is largely determined by access to ovipositing females… Show more

“…These inconsistent results might have been due to different experimental designs used in these studies. Specifically, Yeates et al (2009) used paired-male fertilization trials, which more accurately reflect natural spawning conditions in salmonids (Fleming, 1998), while other studies used single-male (no choice) fertilization trials (Wedekind et al, 2004;Skarstein et al, 2005). Furthermore, each of these studies examined the impact of only one MHC locus on fertilization outcome.…”

“…Atlantic salmon, Salmo salar, exhibit spectacular male alternative reproductive life histories that are the result of developmental plasticity. Males either attain sexual maturity precociously as parr (first reproduction at 1-3 years) to become sneakers (stealing mating) that are 10 times smaller than their migratory conspecifics or migrate out to sea and return at the age of 3-7 years as large anadromous animals (Fleming 1998). The quantitative genetic, behavioural and physiological differences between sneakers and immature males have been studied extensively (figure 1; Hutchings & Myers 1994;Aubin-Horth & Dodson 2004).…”

“…Aggressive behavior, including displaying, chasing, and biting, can also occur in both sexes, with the advantage usually going to the larger individual-size matters more to males than females-or to the individual that has already established a territory (Fleming 1998). Larger individuals are less likely to spawn again than smaller individuals, and females are more likely to exhibit repeat spawning than males.…”
