飼育下におけるノトイスズミの日間採餌量の見積と採餌日周性の検討 Estimation of daily feeding rate and diel feeding rhythm of herbivorous fish Kyphosus bigibbus in captivity Noda, Mikio 1259 野田, 幹雄 40399663 ノダ, ミキオ Kawano, Masahiro 川野, 正弘 カワノ, マサヒロ Okamoto, Kuniaki 岡本, 訓明 オカモト, クニアキ Murase, Noboru 1245 村瀬, 昇 60399665 ムラセ, ノボル Herbivorous fish; Daily feeding rate; Diel feeding; Kyphosus; Nocturnal browsing Daily feeding rate in relation to temperature and diel feeding rhythm of the grey sea chub Kyphosus bigibbus were examined for Eisenia bicyclis and Sargassum patens forming seaweed beds under tank-rearing condition. Daily feeding rate of K. bigibbus ranged from 0.7 to 1.3% for E. bicyclis and from 3.4 to 4.6% for S. patens (in the temperature range from 20 to 30℃) and the fish showed almost no feeding at 12℃ K. bigibbus constantly fed on algae at night as well as in the daytime and in particular showed the most intensive feeding activity before sunset and after sunrise. 編集：水産大学校 departmental bulletin paper 水産研究・教育機構 Japan Fisheries Research & Education Agency 2016-03-31 application/pdf 水産大学校研究報告 4 64 219 225 Journal of National Fisheries University AN00124678 0370-9361 https://fra.repo.nii.ac.jp/record/2012075/files/fishu_k_64_219.pdf https://fra.repo.nii.ac.jp/records/2012075 jpn fishu_k_64_219 agriknowledge https://agriknowledge.affrc.go.jp/RN/2010922150 open access
