鳥取県沖日本海産メイタガレイの2型, ホンメイタとバケメイタの形態比較 Morphological Comparison of Two Types of Frog Flounder, Pleuronichthys cornutus, Collected off Tottori Prefecture, in the Japan Sea 野沢, 正俊 ノザワ, マサトシ Nozawa, Masatoshi 野沢 ノザワ Nozawa 正俊 マサトシ Masatoshi 鳥取県水産試験場 トットリケンスイサンシケンジョウ Tottori Prefectural Fisheries Experimental Station 加藤, 史彦 カトウ, フミヒコ Kato, Fumihiko 加藤 カトウ Kato 史彦 フミヒコ Fumihiko metadata only access The frog flounder, Pleuronichthys cornutus, one of the most important groundfish species in the western Japan Sea, is here divided into two types basing on morphological examinations. They are conveniently called "Honmeita" and "Bakemeita" by fishermen in Tottori Prefecture. The present paper deals with the morphological comparison between these two types. The results obtained are summarized as follows: 1) Morphometric measurements were done for 7 body parts and 8 meristic characters on about 100 specimens of two types in question. 2) T-test and variance analysis revealed that all meristic characters tested have significant differences between two types. The mean numbers of vertebrae, dorsal fin rays and anal fin rays were larger in "Honmeita" than in "Bakemeita". 3) Regression analysis was made of 6 morphometric characters on body length. A significant difference of regression coefficient between two types was found in one character, body height. 4) "Honmeita" and "Bakemeita" were considered to be corresponding to MDH-A and MDH-B types respectively, which had been divided by KATO.FUJIO (1979) by means of isozyme analysis for malate dehydrogenase. "Honmeita" was also identical to "Meitagarei" described by OCHIAI (1976). 日本海区水産研究所 Japan Sea Regional Fisheries Research Laboratory 1981-09-28 jpn departmental bulletin paper https://fra.repo.nii.ac.jp/records/2002548 js_k_32_1_8 https://agriknowledge.affrc.go.jp/RN/2010241156 日本農学文献記事索引(agriknowledge) AN00186380 0021-4620 日本海区水産研究所研究報告 Bulletin of the Japan Sea Regional Fisheries Research Laboratory 32 8 1 8
