内容記述
"In order to clarify the seasonal variations of sea conditions, fishing grounds of set nets and fishing conditions of gill nets in the sea around the Uji-Islands, oceanographical observations and fishing experiments have been carried out on the training ships of the Faculty of Fisheries, Kagoshima Univ., “Shiroyama”, and “Nansei-Maru” during the term from March. 1964 to March. 1968.The results obtained are as follows : The range of water temperature and salinity in March lay within 16~17°C, 34.40~35.00% respectively and the variation of water temperature between surface and 30m. layer lay within the range of 1°C and less. The range of transparency in the sea around Uji-Islands was 13~21m. in spring and 18~29m. in autumn. It was assumed that the several locations, Biro-Bay, Kataura-Hato, Tomoga-Ura and Jugohiro-Ura are well situated to set a set net or a bottom fixed set net. Many kinds of fish, Pseidipeneus spilurus BLEEKER, Leptoscarus japonicas CUVIER&VALENCIENNES, Goniistius zonatus CUVIER et VALENCIENNES and etc. are captured by a Mie-ami, triple net in spring, summer and autumn."
