We studied reproductive ecology of this fish in one of the subsidiary streams of Kushiro River, eastern Hokkaido. In the study, the spawning period lasted for 37 days from April 1 to May 7. Redds were 65 and the water temperature was from 0.9 to 7.0 degrees Celsius. It is reported that this fish starts spawning at the end of April, the spawning period lasts for 7 to 14 days and the water temperature during spawning term is 3 to 7 degrees Celsius in the rivers in the middle and north of Hokkaido. However, in the river where we conducted this research in the east of Hokkaido, it was observed that the spawning of the fish started about three weeks, earlier than the fish in the rivers in the middle and north of Hokkaido that the spawning period was longer and that the spawning started when the water temperature was still low. It could be estimated that this is because the amount of snow in this area is comparatively small than that of the other areas and the climate conditions and river environment in the melting season differ.","subitem_description_type":"Other"}]},"item_1_description_13":{"attribute_name":"レポート・講演番号","attribute_value_mlt":[{"subitem_description":"E","subitem_description_type":"Other"}]},"item_1_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"7","subitem_description_type":"Other"}]},"item_1_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00005407379","subitem_description_type":"Other"}]},"item_1_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_1_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00164184","subitem_source_identifier_type":"NCID"}]},"item_1_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京農業大学生物産業学研究科生物産業学専攻
