基于在黄海中南部海域采集的23尾体色花纹各异的狮子鱼标本,利用形态学和线粒体DNA 细胞色素氧化酶Ⅰ亚基因(COⅠ)相结合的方法,对黄海中南部海域狮子鱼种类进行了分析。结果显示,22尾标本在可数性状和可量性状,如背鳍、尾鳍、臀鳍、胸鳍、幽门盲囊、头长/体长、头长/吻长、眼间隔/眼径、体高/体长等,属于细纹狮子鱼的范畴。其中4尾标本体表覆盖明显黑褐色横斑。5尾体表覆盖不规则斑纹,眼部存在放射性白色条带,头部及尾部存在明显的纵纹。9尾在头部或体侧具有褐色或者黑褐色细点,臀鳍黑色,尾鳍基部有1白斑。4尾体表尾红褐色,具有纵行细纹,背鳍、尾鳍、臀鳍及胸鳍外缘灰黑色;另1尾根据可数性状判断,其属于网纹狮子鱼,头部和体背部具有大小不等的白色小圆斑,尾长形、后端圆凸,背鳍基部两侧具有6–7个密集的斑点。COⅠ分析也具有相同的结果,其中22尾细纹狮子鱼之间的遗传距离为0.002–0.003,与网纹狮子鱼的遗传距离为0.134,与其他种类如戴氏狮子鱼、细尾狮子鱼、光皮狮子鱼等的遗传距离较近,为0.057–0.067。
基于在黃海中南部海域採集的23尾體色花紋各異的獅子魚標本,利用形態學和線粒體DNA 細胞色素氧化酶Ⅰ亞基因(COⅠ)相結閤的方法,對黃海中南部海域獅子魚種類進行瞭分析。結果顯示,22尾標本在可數性狀和可量性狀,如揹鰭、尾鰭、臀鰭、胸鰭、幽門盲囊、頭長/體長、頭長/吻長、眼間隔/眼徑、體高/體長等,屬于細紋獅子魚的範疇。其中4尾標本體錶覆蓋明顯黑褐色橫斑。5尾體錶覆蓋不規則斑紋,眼部存在放射性白色條帶,頭部及尾部存在明顯的縱紋。9尾在頭部或體側具有褐色或者黑褐色細點,臀鰭黑色,尾鰭基部有1白斑。4尾體錶尾紅褐色,具有縱行細紋,揹鰭、尾鰭、臀鰭及胸鰭外緣灰黑色;另1尾根據可數性狀判斷,其屬于網紋獅子魚,頭部和體揹部具有大小不等的白色小圓斑,尾長形、後耑圓凸,揹鰭基部兩側具有6–7箇密集的斑點。COⅠ分析也具有相同的結果,其中22尾細紋獅子魚之間的遺傳距離為0.002–0.003,與網紋獅子魚的遺傳距離為0.134,與其他種類如戴氏獅子魚、細尾獅子魚、光皮獅子魚等的遺傳距離較近,為0.057–0.067。

To identify snailfish specimens collected in the central and southern Yellow Sea, both morphology method and cytochrome oxidase subunit geneⅠanalysis were conducted in this paper. The results showed that 22 specimens were Liparis tanakae according to meristic and measurable characteristics, including the fin ray number of pectoral fin, anal fin, dorsal fin, caudal fin, the number of pyloric caecum, the ratios of head length/body length, body depth/body length, head length/snout length, interorbital space/eye diameteretc. In allL. tanakaespecimens, 4 specimens were covered with obvious brown transverse spots. Five specimens had irregular spots, white radiation lines in ocular region, obvious longitudinal grain in the head and caudal fin. Nine specimens had the brown or black brown fine spots on the head and body side, one white patch in the base of caudal fin, and black anal fin. Another 4 specimens had reddish-brown with longitudinal striate, the fin membrane edge of dorsal fin, anal fin, pectoral fin, and caudal fin. There was one specimen belonged toLiparis chefuensis that had the irregular white spots in the head and body back, long caudal fin, the round convex at its back end, 6?7 dense spots in the two sides of the base of dorsal fin. These results were supported by the cytochrome oxidase subunit geneⅠanalysis. The genetic distance between 22L. tanakae specimens were 0.002?0.003, and the genetic distance betweenL. tanakae andL. chefuensis was 0.134. The genetic distance betweenL. tanakaeand the other species, for exampleL. dennyi, L. gibbus, L. fucensis were 0.057?0.067. These findings indicated that Liparidae species in the Yellow Sea were mainly composed ofL. tanakae.
