奄美リュウキュウアユ仔魚の餌環境 および栄養状態の定量的評価に関する研究 Study on Quantitative Evaluation of Food Availability and Nutritional Conditions for Fish Larvae, Plecoglossus altivelis ryukyuensis 1000060336328 小針, 統 KOBARI, Toru 杉本, 智 SUGIMOTO, Satoru 1000090041722 四宮, 明彦 SHINOMIYA, Akihiko 1000060332897 河合, 渓 KAWAI, Kei 20253388 西村, 知 Nishimura, Satoru 0000000111671801 open access We carried out plankton sample collections on Yakugachi river in Amami Island and incubation experiments of fish larvae Plecoglossus altivelis ryukyuensis to evaluate food availability and nutritional conditions. High turbidity was evident for the stations on the tidal flat where salinity showed a high variability, while chlorophyll was high on the tidal flat and at the offshore stations. We suggest that not only salinity but also food availability might be responsible for frequent occurrence of the larvae on the tidal flat. We will evaluate food availability and nutritional conditions for the larvae from more analyses of field sample and incubation experiments. 鹿児島大学 Kagoshima University 2011-03-31 jpn departmental bulletin paper VoR http://hdl.handle.net/10232/12801 https://ir.kagoshima-u.ac.jp/records/7953 13450441 AN1013531X 南太平洋海域調査研究報告 Occasional papers 52 51 55 https://ir.kagoshima-u.ac.jp/record/7953/files/AN1013531X_v52_p51-55.pdf application/pdf 1.0 MB 2016-10-28 2011-03-31
