Seamount coral reefs are egg case nurseries for deep-sea skates, Tasman Fracture and Huon Australian Marine Parks (AMP), Tasmania, Australia (2018)

Egg case nurseries of the boreal skate (Amblyraja hyperborea) and Richardson's skate (Bathyraja richardsoni) were defined and mapped on a bathyal seascape (c. 5001900 m depths) of the Tasman Fracture and Huon Australian Marine Parks, south of Tasmania, Australia in 2018, using 99 towed-camera transects (157 linear km; N = 50,858 images). In total, 738 skate egg cases were observed (present in 240 images, absent in 50,618); among 113 egg cases examined to identify parent species, 70% were A. hyperborea, 10% B. richardsoni and 20% unidentified Bathyraja species.

2018年，研究人员借助99条牵引相机样带（总线性长度157千米，共获取50858幅图像），在澳大利亚塔斯马尼亚以南的塔斯曼断裂带（Tasman Fracture）与胡恩澳大利亚海洋公园（Huon Australian Marine Parks）的半深海海域生境（水深约500–1900米）中，对北方鳐（Amblyraja hyperborea）及理查森鳐（Bathyraja richardsoni）的卵囊育幼场进行了界定并绘制空间分布图。
本次调查总计观测到738个鳐鱼卵囊，其中240幅图像中存在卵囊，剩余50618幅未观测到；在用于鉴定亲本物种的113个卵囊中，70%为北方鳐，10%为理查森鳐，余下20%为未鉴定的深海鳐属（Bathyraja）物种。
