The extent to which stray, hatchery-reared salmon affect wild populations is much debated. Although experiments show that artificial breeding and culture influence the genetics of hatchery salmon, little known about interaction between in a natural setting. Here, we estimated historical contemporary genetic population structures chum (Oncorhynchus keta) Prince William Sound (PWS), Alaska, with 135 single nucleotide polymorphism (SNP) markers. Historical structure was inferred from analysis...
Abstract Changes in trophic position estimates of commercial fishery catches are used as an ecosystem‐based indicator for sustainability, but often these do not incorporate species‐specific seasonal feeding dynamics and ontogenetic diet changes. Using stable isotope analysis, we obtained a fine‐scale resolution temporal (interannual seasonal) variations the roles four commercially ecologically important groundfish species Gulf Alaska: walleye pollock Theragra chalcogramma , Pacific cod Gadus...
