利用

量少,漁民以底拖網捕獲;除當下雜魚製作成魚粉利用外,漁業之經濟價值較低,但極具分類研究之意義。

描述

provided by The Fish Database of Taiwan
身體延長,尾部側扁漸細,頭部及身體呈暗黑色,全長為鰓孔位體高及肛門位體高之17.8-20.6及26.6-30.0倍;肛門位於全長中點之前,肛門前長佔全長的35-36 %;尾長延長,其長度約為肛門前長的1.8倍;尾端柔軟,易彎折,尾部末端鰭條延長;背鰭起點位於胸鰭基部上方或略後方;奇鰭具有黑色邊緣,鰭條分節;胸鰭位於體高中點偏下方,胸鰭基部上緣約與眼睛下緣水平線等高;鰓孔為圓孔狀,位於身體側邊中點之下方;全長為頭長之8.0-8.1倍,吻端長且略呈尖狀,口裂末端超過眼睛水平中點,但未到達眼睛後緣之下方,上顎略長於下顎,吻長大於眼直徑,吻長為眼直徑之2.4-2.6倍;眼睛較小,約占頭長的11-12%;嘴唇不具上唇瓣;前鼻孔為短管狀,靠近吻端,後鼻孔為圓形,位於眼睛垂直中點之前方。 上眼窩有2個感覺孔,下眼窩有5-6個感覺孔,前鰓顎有10個感覺孔,顳骨接合處有1個感覺孔;肛門前背鰭鰭條數為62-65;背鰭前側線孔數6-7,胸鰭前側線孔數6,肛門前側線孔數41;背鰭前脊椎骨數10,肛門前脊椎骨數47,總脊椎骨數175+-192ca.。本種以往皆被鑑定為(/B. vicinus/),此2種之差異在於本種的鰓孔小,約僅有眼睛直徑之ㄧ半;本種之背鰭起點較前方,位於胸鰭基部的略後方;背鰭前側線感覺孔及脊椎數皆較(/B. vicinus/)少。臺灣過去的文獻並無記錄此種,故視為新記錄種。
