Field Science Center for Northern Biosphere, Division of Biosphere Science, Graduate School of Environmental Science, Hokkaido University, Kita ku, Sapporo, Hokkaido, Japan
J Fish Biol 81:543-58. 2012..These findings are discussed in relation to the physiological mechanisms of imprinting and homing migration in anadromous and lacustrine salmonids...
Physiological mechanism of homing migration in Pacific salmon from behavioral to molecular biological approachesHiroshi Ueda
Laboratory of Aquatic Bioresources and Ecosystem, Field Science Center for Northern Biosphere, Division of Biosphere Science, Graduate School of Environmental Science, Hokkaido University, Sapporo, Hokkaido 060 0809, Japan
Gen Comp Endocrinol 170:222-32. 2011..These results have discussed with the evolutional aspects of four Pacific salmon, sexual differences in homing profiles, and the possibility of dissolved free amino acids (DFAA) as natal stream odors for salmon...
Year-to-year differences in plasma levels of steroid hormones in pre-spawning chum salmonTakeshi Onuma
Division of Biological Sciences, Graduate School of Science, Hokkaido University, Sapporo, Hokkaido 060 0810, Japan
Gen Comp Endocrinol 133:199-215. 2003..The present results showed that there were year-to-year differences in plasma levels of steroid hormones and maturity, and some of them may be influenced by the year-to-year variation of SST...
Synergistic effects of salmon gonadotropin-releasing hormone and estradiol-17beta on gonadotropin subunit gene expression and release in masu salmon pituitary cells in vitroHironori Ando
Division of Biological Sciences, Graduate School of Science, Hokkaido University, Sapporo, Hokkaido 060 0810, Japan
Gen Comp Endocrinol 137:109-21. 2004..The synergistic interaction modulates GTH synthesis differentially, depending on subunit, stage, and gender, whereas it potentiates the activity of GnRH to release GTH in any situation...
EMG telemetry studies on upstream migration of chum salmon in the Toyohira River, Hokkaido, JapanYuya Makiguchi
Division of Biosphere Science, Graduate School of Environmental Science, Hokkaido University, Sapporo, Hokkaido 060 0809, Japan
Fish Physiol Biochem 37:273-84. 2011..It is important that fishway are constructed to enable chum salmon to find a passage way easily, so that they can migrate upstream rapidly without wasting excessive energy...
Olfactory responses to natal stream water in sockeye salmon by BOLD fMRIHiroshi Bandoh
Division of Biosphere Science, Graduate School of Environmental Science, Hokkaido University, Sapporo, Japan
PLoS ONE 6:e16051. 2011..We concluded that sockeye salmon could process the odor information of the natal stream by integrating information in the Dl area of the telencephalon...
Seasonal changes of responses to gonadotropin-releasing hormone analog in expression of growth hormone/prolactin/somatolactin genes in the pituitary of masu salmonRamji Kumar Bhandari
Division of Marine Biological Sciences, Graduate School of Fisheries Science, Hokkaido University, Hakodate, Hokkaido 041-8611, Japan
Gen Comp Endocrinol 130:55-63. 2003..In growing and maturing masu salmon, expression of genes encoding GH, PRL, and SL in the pituitary is thus sensitive to GnRH in particular seasons probably in relation to physiological roles of the hormones...
Seasonal variation in the expression of five subtypes of gonadotropin-releasing hormone receptor genes in the brain of masu salmon from immaturity to spawningAya Jodo
Division of Biological Sciences, Graduate School of Science, Hokkaido University, Sapporo, Japan
Zoolog Sci 22:1331-8. 2005..Furthermore, E2 may be involved in msGnRH-R gene expression in the brain of female masu salmon during sexual maturation...
Seasonal changes in expression of genes encoding five types of gonadotropin-releasing hormone receptors and responses to GnRH analog in the pituitary of masu salmonAya Jodo
Division of Biological Sciences, Graduate School of Science, Hokkaido University, Sapporo 060-0810, Japan
Gen Comp Endocrinol 144:1-9. 2005..These results indicate that the expression of the five GnRH-R genes is seasonally variable and may be related to the responses of the pituitary hormone genes to GnRH, and the regulation of GnRH-R genes by GnRH is different in both sexes...
Olfactory imprinting of amino acids in lacustrine sockeye salmonYuzo Yamamoto
Laboratory of Aquatic Bioresources and Ecosystem, Field Science Center for Northern Biosphere and Division of Biosphere Science, Graduate School of Environmental Science, Hokkaido University, Sapporo, Hokkaido, Japan
PLoS ONE 5:e8633. 2010..We conclude that one-year-old lacustrine sockeye salmon can be imprinted by a single amino acid before and during PST, and that imprinting requires exposure for at least 14 days...
Cardiac arrest during gamete release in chum salmon regulated by the parasympathetic nerve systemYuya Makiguchi
Division of Biosphere Science, Graduate School of Environmental Science, Hokkaido University, Sapporo, Hokkaido, Japan
PLoS ONE 4:e5993. 2009..This cardiac arrest represents a response to the gaping behavior that occurs at the moment of gamete release...
Behavioral responses by migratory chum salmon to amino acids in natal stream waterYuzo Yamamoto
Division of Biosphere Science, Graduate School of Environmental Science and Laboratory of Aquatic Bioresources and Ecosystems, Field Science Center for the Northern Biosphere, Hokkaido University, Kita ku, Sapporo 060 0809, Japan
Zoolog Sci 26:778-82. 2009..These results suggest that migratory male chum salmon respond to amino acid mixtures in their natal stream water and appear to be affected by multiple amino acids...
