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 capsule measures 92-103 mm long and 72-80 mm wide (Ref. 41249). Utilized as fishmeal (Ref. 6077).
卵生的。 明显的成对出现。 幼鱼可能倾向跟随大的个体, 例如他们的母亲.(参考文献 205) 卵为长方形鞘囊具有僵硬的触角沈积在沙滩或泥滩的角落.(参考文献 205) 卵鞘有 92-103 mm 长与 72-80 mm 宽的长。 (参考文献 41249) 用来作鱼粉了。 (参考文献 6077)
