Changes of triglyceride and glycogen levels in the liver of underyearling masu salmon Oncorhynchus masou during starvation

Diurnal changes in salmon GnRH secretion in the brain of masu salmon (Oncorhynchus masou).

The day-night changes of salmon GnRH (sGnRH), which is secreted from various brain regions, were analyzed in maturing and matured masu salmon (Oncorhynchus masou). In maturing males, the levels of sGnRH secreted from the olfactory bulb (OB), terminal nerve (TN), and ventral telencephalon and preoptic area (VT+POA) were all significantly higher during midnight than daytime. However, the contents...

[Comparative analyses of allergens between landlocked and anadromous species of masu salmon Oncorhynchus masou masou].

Although the difference in allergenicity between landlocked and anadromous salmon is little understood, only anadromous salmon are recommended to be labeled in the current allergen labeling system. This study was designed to examine the allergenic potency of landlocked species (yamame) and anadromous species (sakuramasu) of masu salmon Oncorhynchus masou masou, with special reference to parvalb...

Migratory Behaviors in Masu Salmon (Oncorhynchus masou) and the Influence of Endocrinological Factors

© 2012 TERRAPUB, Tokyo. All rights reserved. doi:10.5047/absm.2012.00502.0029 and Kobayashi 2010). Most of the non-migratory forms will live continuously in their natal rivers throughout their lives (Fig. 1). Regardless of these life history types, most salmonids will spawn in freshwater environments, mainly in their natal rivers (Fig. 1) (Quinn 2005). From these phenomena, salmonids are consid...

Population genetic structure and phylogeography of masu salmon (Oncorhynchus masou masou) inferred from mitochondrial and microsatellite DNA analyses.

The population genetic structure and phylogeography of masu salmon were investigated by using variation in the mitochondrial NADH dehydrogenase subunit 5 gene (ND5) and six polymorphic microsatellite loci among a total of 895 fish representing 18 populations collected from Japan (9), Russia (7), and Korea (2) from 2000 to 2008. An analysis of ND5 nucleotide sequences revealed 22 variable sites ...
