耳石解析によるムシガレイ日本海西部群の成長モデルの再検討 Revision of growth model of spotted sole from western waters of the sea of Japan using otolith analysis Imai, Chifumi 2032 今井, 千文 80399633 イマイ, チフミ Miyazaki, Yoshinobu 3044 宮崎, 義信 ミヤザキ, ヨシノブ Growth model of spotted sole Eopsetta grigorjewi from western waters of the Sea of Japan was revised using otolith analysis. Total length TL (cm) back calculation models from otolith radius R (mm) using biological intercept, TL=0.35+8.38R+0.166R 2 (female), TL=0.35+9.12R (male TL<21.5), TL=4.57+7.30R (male TL>21.5) and TL=0.35+8.57R+0.0714R 2 (both sexes) were taken. Total length at each ring formation (outer edge of opaque zone) was back calculated from mean radius using above models. Assuming age at i-th ring formation was i-0.5, the von Bertalanffy growth models, Lt=48.7 { 1 -e -0.158(t+0.610)} (female), L=33.4 { -e -0.303(t+0.380)} (male) and Lt=46.0 {1 -e -0.171(t+0.582)} (both sexes) were taken by non-linear least square method. BW (g) -TL relationships were quantified by BW=0.00253TL 3.41 (female), BW=0.00165TL 3.54 (male) and BW=0.00292TL 3.37 (both sexes). TL and standard length SL (cm) of both sexes showed clear linear relationship with regression line, TL=0.785+1.15SL (r=0.982). departmental bulletin paper 水産大学校 National Fisheries University 2005-01-31 application/pdf 水産大学校研究報告 1 53 21 34 Journal of National Fisheries University AN00124678 0370-9361 https://fra.repo.nii.ac.jp/record/2011791/files/fishu_k_53_21.pdf https://fra.repo.nii.ac.jp/records/2011791 jpn fishu_k_53_21 agriknowledge https://agriknowledge.affrc.go.jp/RN/2010721506 open access
