In Asia, there are two distinct types of chum salmon (Oncorhynchus keta Walbaum). The early-maturing or “summer” chum salmon generally returns to spawn from June through August in streams bordering Kamchatka, the Sea of Okhotsk, the east coast of Sakhalin Island, and the Amur River. Later-maturing or “autumn” chum salmon generally return to spawn from(More)
The variation in mitochondrial DNA (mtDNA) structure among chinook salmon Oncorhynchus tschawytscha Walbaum populations from Kamchatka was inferred from restriction length polymorphism analysis using eight restriction endonucleases. The nucleotide sequence variation in three amplified mtDNA regions was examined at seven polymorphic restriction sites in 579(More)
Based on the data of Russian and foreign researchers, a database, consisting of 100 allozyme-coding loci examined in 288 chum salmon populations from Asia and Northern America, was constructed. Using G-test, genetic heterogeneity of Asian population samples of chum salmon was evaluated. Correlations between the frequencies of major alleles and geographic(More)
