摘要:

2016年10月采自北部湾海域的1尾鱼类标本经鉴定为线鳍鲆属Taeniopsetta Gilbert, 1905的眼斑线鳍鲆Taeniopsetta ocellata(Günther, 1880), 隶属于鲽形目Pleuronectiformes鲆科Bothidae, 这是该属和种首次在中国大陆海域的报道。线鳍鲆属的主要形态特征包括: 体长卵圆形; 双眼位于头左侧; 口小; 有眼侧和无眼侧均有1行小尖牙; 鳞细小, 仅体左侧有1条侧线; 雄鱼有1枚强吻棘和2或3枚眼棘, 雌鱼吻棘和眼棘很钝或无; 无眼侧腹鳍始于有眼侧第2根腹鳍鳍条基部右侧; 腹鳍基较短; 背鳍和臀鳍的部分鳍条延长成丝状。眼斑线鳍鲆的主要形态特征为: 两侧胸鳍不等长; 雄鱼背鳍的第13~17根鳍条及臀鳍的第1~6根鳍条延长成丝状; 体左侧背腹缘分别有2~4个不规则的“V”形或半圆形中空黑色斑块, 斑块内部具一黄色圆斑。

Abstract:

A specimen collected from the Beibu Gulf in October 2016 was identified as Taeniopsetta ocellata (Günther, 1880) belonging to genus Taeniopsetta (Pleuronectiformes: Bothidae). Such genus and species are reported for the first time from the coastal waters of mainland China. Characters of genus Taeniopsetta mainly include the following: body ovate; both eyes on the left side of body; mouth rather small; teeth uniserial on both sides; scales small, lateral line only on ocular side, absent on blind side; one strong rostral and two or three orbital spines present in males, feeble or absent in females; first ray of ventral fins on the blind side opposite to the second ray on the ocular side; base of ventral fins short; and some of the rays of the dorsal and anal fins prolonged into filaments. The diagnostic features of T. ocellata are as follows: pectoral fins unequal on both sides; the 13th to 17th dorsal-fin rays and six anterior rays of anal fins elongated and filamentous in males; 2~4 irregular V-shaped or semicircular hollow blotches within yellow spots on the upper and lower body on the ocular side.
