Life Cycle

Oviparous (Ref. 9908). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).

Biology
provided by Fishbase
Bottom-dwellers that feed on invertebrates and bony fish (Ref. 9908). Depth range given by H. Ishihara (pers.comm. 07/07). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 5.3-6.7 cm long and 2.7-3.9 cm wide (Ref. 41253, 41298).

利用
provided by The Fish Database of Taiwan
拖網漁業所混獲的魚種,較無經濟價值,可提供養殖用的飼料使用,但近年來由於傳統經濟性種類漁獲數量有逐漸下降的趨勢,因此也開始有食用小型鰩種的情形發生。

雄魚吻長為頭長的1.9—2.5倍,雌魚則為1.8-1.9倍。尾長平均約為體盤寬的1.2-1.4倍。兩眼眶間距狹窄,且距離大於眼徑大小。體盤背部及腹部平滑,體盤背部前緣及吻端及兩背鰭、尾鰭有微小的刺。眼眶邊緣有6-13根刺,項棘約1-5根;尾部有3列以上棘刺。體盤背部呈黑褐色,上有許多黑巧克力色的小點分布,在胸鰭後緣的角落有一對暗色眼點,腹部及尾部有(或無)不規則的灰白色斑點,但胸鰭及腹鰭外緣無分布。吻軟骨接近頭蓋骨;腹部及背鰭前的脊椎骨數為28-29根、38-32根。腸瓣6-7個。交接器有較大的SH(sentinel)及一個扇形開口(rhipidion),內部的輔端軟骨AT-1(accesssory
terminal 1.)延長且不對稱。(陳柔蓉、林沛立2012/11編寫)
