Recurrent evolution of life history ecotypes in sockeye salmon: implications for conservation and future evolution
We examine the evolutionary history and speculate about the evolutionary future of three basic life history ecotypes that contribute to the biocomplexity of sockeye salmon (Oncorhynchus nerka). The 'recurrent evolution' (RE) hypothesis claims that the sea/river ecotype is ancestral, a 'straying' form with poorly differentiated (meta)population structure, and that highly structured populations o...
متن کاملEvaluating Relationships between Wild Skeena River Sockeye Salmon Productivity and the Abundance of Spawning Channel Enhanced Sockeye Smolts
The enhancement of salmon populations has long been used to increase the abundance of salmon returning to spawn and/or to be captured in fisheries. However, in some instances enhancement can have adverse impacts on adjacent non-enhanced populations. In Canada's Skeena watershed, smolt-to-adult survival of Babine Lake sockeye from 1962-2002 was inversely related to the abundance of sockeye smolt...
متن کاملSpecific PCR for Myxobolus arcticus SSU rDNA in juvenile sockeye salmon Oncorhynchus nerka from British Columbia, Canada.
A PCR for the specific detection of the salmon brain parasite Myxobolus arcticus (Pugachev and Khokhlov, 1979) was developed using primers designed to amplify a 1363 base pair fragment of the small subunit rDNA. The assay did not amplify DNA from 5 other Myxobolus species or from 7 other myxozoan species belonging to 5 other genera. For juvenile sockeye salmon Oncorhynchus nerka (Walbaum) colle...
متن کاملApplication of Microsatellite DNA Variation to Estimation of Stock Composition and Escapement of Skeena River Sockeye Salmon (Oncorhynchus nerka)
Microsatellite loci can be used to estimate spawning escapements of individual Pacific salmon populations returning to remote spawning locations throughout large river systems by analysis of appropriately weighted samples from test fisheries near the river mouth. Variation at six microsatellite loci (Omy??, Ots3, Ots3, Ots3, Ots3, and Ots3) was surveyed from approximately 1,700 sockeye salmon (...
متن کاملPhylogenetic relationship of the genus Oncorhynchus species inferred from nuclear and mitochondrial markers.
The phylogenetic relationship among the salmonid fishes of the genus Oncorhynchus has been analyzed using various kinds of markers for a long time. However, there are three major disagreements among those studies; (1) the authenticity of the Pacific salmon group as a monophyletic cluster, (2) the phylogenetic relationship among three Pacific salmons (pink salmon, sockeye salmon, and chum salmon...
