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 小針, 統 7932 KOBARI, Toru 1000060336328 杉本, 智 107590 SUGIMOTO, Satoru 四宮, 明彦 2370 SHINOMIYA, Akihiko 1000090041722 河合, 渓 5249 KAWAI, Kei 1000060332897 西村, 知 10240 Nishimura, Satoru 20253388 096 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. departmental bulletin paper 鹿児島大学 Kagoshima University 2011-03-31 VoR application/pdf 南太平洋海域調査研究報告 52 51 55 Occasional papers 13450441 AN1013531X https://ir.kagoshima-u.ac.jp/record/7953/files/AN1013531X_v52_p51-55.pdf http://hdl.handle.net/10232/12801 https://ir.kagoshima-u.ac.jp/records/7953 jpn open access
