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

Occur in the sublittoral zone, 70-90 m on sandy mud bottoms (Ref. 11230). 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 measure 6.1 cm long and 3.7 cm wide (Ref. 41249). Utilization details sketchy (Ref. 9908). Very rarely caught by demersal longline fisheries off Java. Utilized for its meat (Ref.58048).

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。
