“…Earlier, analysis of allozyme variation in sockeye salmon showed that geographic distances among populations were only slightly associated with the corresponding genetic distances [7,17,18]. Some authors attribute this mainly to the history of formation of the modern sockeye salmon range, in particular, the origin of geographically close populations from different sources [17,18]. Our data to some extent support this assumption.…”

“…Thus, this species is expected to display high intraspecific genetic subdivision. Previously, using other molecular markers (allozymes [17,18], combined allozyme and mtDNA data [19], and microsatellite DNA [20][21][22]), it has been shown that genetically different sockeye populations occur at relatively small geographic distances. Possible rapid divergence of sockeye subpopulations, even sympatric ones, has been shown for several Alaskan lakes [23].…”

“…In our case, the effect of this factor on genetic differentiation of sockeye populations was less pronounced and recorded only for the lake populations. Earlier, analysis of allozyme variation in sockeye salmon showed that geographic distances among populations were only slightly associated with the corresponding genetic distances [7,17,18]. Some authors attribute this mainly to the history of formation of the modern sockeye salmon range, in particular, the origin of geographically close populations from different sources [17,18].…”

The Effect of Reproduction Biotopes on the Genetic Differentiation of Populations of Sockeye Salmon Oncorhynchus nerka

Variation of mitochondrial DNA (mtDNA) was examined in nine populations from three lake-river systems of Chukotka and Kamchatka. Significant differences were found between most of the sockeye salmon samples studied. The genetic differences among populations were not high and often did not correlate with the geographical distances between them. The low population divergence is explained by a short time of existence of most of them, having been formed after the recession of the upper Pleistocene glacier. When the populations were grouped according to their spawning biotopes (river or lake), they in general appeared more genetically similar than upon their grouping by geographical location (the lake-river systems). The differences between the river and lake populations in the lake-river systems increased from north to south. GENERAL GENETICSRUSSIAN JOURNAL OF GENETICS Vol. 41 No. 5 2005 BRYKOV et al .

“…This homing behavior isolates spawning groups so that random genetic drift and local selection produce differences among groups, which can often be detected with molecular markers (Grant et al 1980;Hendry et al 1996Hendry et al , 2000Seeb et al 2000). Although lake and stream spawners often differ genetically, less variation among spawning groups occurs within lakes (Varnavskaya et al 1994;Burger et al 1995;Seeb et al 2000;Habicht et al 2007;Gomez-Uchida et al 2011).…”

The supplementation of natural populations of Pacific salmon Oncorhynchus spp. with hatchery fish poses unique management challenges. Two such challenges addressed in this study are limiting the number of hatchery fish spawning with natural‐origin fish and maximizing the number of natural‐origin fish in the supplementation broodstock. In this study, we focus on stock enhancement of Sockeye Salmon O. nerka in Hidden Lake, Alaska, where the Trail Lakes Hatchery supplements the natural population with hatchery‐raised fry. Production in Hidden Lake is limited by the availability of spawning habitat and not by juvenile rearing capacity. The hatchery collects broodstock from the lake and releases fry with thermally marked otoliths at one of two primary natural spawning sites in Hidden Lake each year. During this study, an average of 58% of the fish returning to the lake through a weir on the outlet stream were of hatchery origin. However, an average of 88% of the fish at the release site were hatchery‐origin fish, indicating a nonrandom distribution of hatchery‐origin spawners. This pattern is consistent with homing to specific sites within the lake of either or both hatchery‐ and wild‐origin fish. However, this distribution results in a larger‐than‐desirable proportion of hatchery‐origin fish spawning with natural‐origin fish at the release site. The proportion of hatchery‐origin fish used for brood is also larger than desirable because the site is also the broodstock collection site. We propose that releasing hatchery fish at a new location removed from the primary spawning areas and the hatchery broodstock collection site will reduce the proportion of hatchery‐origin fish spawning with wild‐origin fish and increase the proportion of wild‐origin fish in the broodstock, if our results are due, at least in part, to homing of hatchery fish.

“…For example, anadromous fish usually show high site fidelity for reproduction (Nielsen et al 1999;Waters et al 2000;King et al 2001), which is referred to as philopatry or homing behaviour. When repeated over several generations, natal site fidelity restricts gene flow and allows progressive genetic differentiation and population structuring among spawning populations, even in the absence of geographic barriers (Leider et al 1984;Varnavskaya et al 1994;Hendry et al 1995).…”

Natal site fidelity of the northern redbelly dace (Phoxinus eos), a common minnow in North America, was confirmed by combining ecological and genetic approaches. A 2-year mark-recapture experiment conducted at four sites separated by 50-450 m strongly supported the propensity of the dace to practice site fidelity during the reproductive period. Individuals recaptured at their marking sites were characterized with five microsatellite loci. Hardy-Weinberg equilibrium and allelic differentiation tests revealed that the fish from different sites significantly differed from a single panmictic and genetically uniform population, thus confirming the homing behaviour of the dace. The detection of a pattern of isolation by distance revealed that migration mostly occurred between nearby sites and decreased as distance from birth site increased. When considering the high population density of dace, their high swimming capability, the distribution of the spawning sites along the littoral zone, and the small size of the lake studied (<5 ha), these results strongly suggest natal site fidelity in this species. The detection of this phenomenon for this species is extremely useful for empirical investigations of factors affecting patterns of isolation by distance and of evolutionary perspectives of natal site fidelity in fishes.Résumé : Un comportement de fidélité au site de naissance du ventre rouge du nord (Phoxinus eos), un cyprin commun d'Amérique du Nord, a été confirmé par la combinaison d'approches écologique et génétique. Une expérience de marquage et recaptures répétées pendant 2 années sur quatre sites distants de 50 à 450 m supporte fortement la propension du cyprin au comportement de fidélité au site en période de reproduction. Les individus recapturés à leur site de marquage ont ensuite été caractérisés avec cinq microsatellites. Les tests d'équilibre de Hardy-Weinberg et de différenciation alléli-que révèlent que les poissons des différents sites diffèrent significativement d'une population panmictique et génétique-ment uniforme, ce qui confirme le comportement de fidélité au site de naissance du cyprin. La détection d'un patron d'isolement par la distance révèle que les échanges de migrants sont plus importants entre des sites rapprochés et diminue avec une augmentation de la distance entre les sites de naissance et de ponte. En considérant la forte densité de cette population de cyprins, leur importante capacité natatoire, la distribution des sites de ponte le long de la zone littorale et la petite taille du lac étudié(<5 ha), ces résultats indiquent fortement l'existence d'un comportement de fidélité au site de naissance chez cette espèce. La détection de ce phénomène chez cette espèce la rend extrêmement utile pour l'étude empirique des facteurs qui affectent le patron d'isolement par la distance et des perspectives évolutives de la fidélité au site de naissance chez les poissons.
