Population structure of chum salmon (Oncorhynchus keta) across the Pacific Rim, determined from microsatellite analysis
Delineation of phylogenetically and adaptively distinct groups in the distribution of chum salmon around the Pacific Rim may lead to conservation of genetic diversity through an understanding of the origin and the evolutionary processes promoting and maintaining genetic differentiation. An evaluation of genetic variation in describing the population structure of salmonids, is a key component in...
متن کاملRecent physical connections may explain weak genetic structure in western Alaskan chum salmon (Oncorhynchus keta) populations
Low genetic divergence at neutral loci among populations is often the result of high levels of contemporary gene flow. Western Alaskan summer-run chum salmon (Oncorhynchus keta) populations demonstrate weak genetic structure, but invoking contemporary gene flow as the basis for the low divergence is problematic because salmon home to their natal streams and some of the populations are thousands...
متن کاملIsolation of apolipoproteins from carotenoid-carrying lipoprotein in the serum of chum salmon, Oncorhynchus keta.
Carotenoid-carrying lipoprotein (CCL) was rapidly isolated from the high density lipoprotein (HDL) fraction of the upstream migrating male chum salmon (Oncorhynchus keta) by a single-step density gradient ultracentrifugation. The two apolipoproteins (Mr = 24,000 and 12,000; designated apo-I and apo-II, respectively) were readily dissociated and separated in 0.1% SDS by gel filtration chromatogr...
متن کاملThe Olfactory Transcriptome and Progression of Sexual Maturation in Homing Chum Salmon Oncorhynchus keta
Reproductive homing migration of salmonids requires accurate interaction between the reception of external olfactory cues for navigation to the spawning grounds and the regulation of sexual maturation processes. This study aimed at providing insights into the hypothesized functional link between olfactory sensing of the spawning ground and final sexual maturation. We have therefore assessed the...
متن کاملMonitoring of Aeromonas salmonicida in Chum salmon (Oncorhynchus keta) from Namdae River, Korea
In this study, 665 chum salmon (Oncorhynkus keta) were caught from Namdae river during 2006 and 2010, and monitored for typical Aeromonas salmonicida, a causative bacterium of furunculosis. 440 adults and 225 artificially hatched fry pools were examined by PCR using the typical A. salmonicida-specific vapA gene primers. The results demonstrated that 43.2% of the samples (287/665 samples) were P...
