日本海におけるスルメイカの分布海域による成長の差異 Spatial Variation in Growth of Japanese Common Squid, Todarodes pacificus STEENSTRUP in the Sea of Japan Kidokoro, Hideaki 478 木所, 英昭 50371894 キドコロ, ヒデアキ 0000-0001-9908-2410 Hiyama, Yoshiaki 601 檜山, 義明 30371975 ヒヤマ, ヨシアキ squid; Ommastrephidae; growth; statolith; Sea of Japan Relationship between body size and age of Japanese common squid, Todarodes pacificus STEENSTRUP which were caught by squid jigging in the Sea of Japan from late June to early July 1994 was examined. From the difference in water temperature observed at stations, the investigated area was divided into the Tsushima current area (warm water area) and cold water area. For males in the maturing stage which were caught abundantly, dorsal mantle length (M.L.), body weight (B.W.), gonad weight and stomach contents were obtained, and their age were determined from daily statolith growth increments. Although there was no significant difference in the mean age (about 240 days) and maturity indices of the specimens, mean M.L. and B.W. of the specimens caught in the cold water area (about 230mm, and 265g) were significantly larger than those of in the Tsushima current area (about 210mm, and 190g). departmental bulletin paper 日本海区水産研究所 Japan Sea National Fisheries Research Institute 1996-03-29 日本海区水産研究所研究報告 46 77 86 Bulletin of the Japan Sea National Fisheries Research Institute AN00186380 0021-4620 https://fra.repo.nii.ac.jp/records/2002446 jpn js_k_46_77_86 日本農学文献記事索引(agriknowledge) https://agriknowledge.affrc.go.jp/RN/2010541840 metadata only access
