Publikováno v: Ecological Indicators, Vol 121, Iss , Pp 107090- (2021)

Surrogacy, whereby the response of a representative species subjected to a stressor is applied to one or more species, is commonly used without validation in conservation research and applications. The objective of this study was to empirically evalu

Partitioning maternal and exogenous diet contributions to otolith 87Sr/86Sr in kokanee salmon (Oncorhynchus nerka)

Autor: Ryan A. Harnish, Timothy J. Linley, Steve D. Shen, Jill M. Janak

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 78:1146-1157

Strontium isotopes (87Sr/86Sr) recorded in the otoliths of Pacific salmon (Oncorhynchus spp.) are commonly used to identify natal origin. For species that migrate at or soon after emergence, the embryonic region of the otolith provides the only recor

Two laboratory studies evaluated small Chinook salmon (Oncorhynchus tshawytscha) (36–99 mm fork length (FL), 0.7%–26.7% tag burden) survival, tag retention, and growth (n = 539) and critical swimming speed (Ucrit; n = 241). Fish were implanted wi
