Early life history of deep-sea demersal fishes collected near-bottom on the upper continental slope of Suruga Bay, Japan

大多数深海底层鱼类的早期生活史仍然不为人所知，尽管有一些上层幼体。我们在T/V Hokuto（东海大学）的每月航行期间，在日本南部骏河湾的上大陆坡（200- 1 000米深）进行了近海底幼虫取样方案。本文报道了光滑薄皮蝇Leptoderma lubricumand L. retropinnum）、双翅目副狮子鱼（Paraliparis dipterus）和巨尾鱼（Coelorinchus kishinouyei）。确定了与水柱有关的三种深海底层鱼类分布格局。展示了骏河湾上陆坡近底物种个体发育的三种类型。

The early life histories of most deep-sea demersal fishes remain unknown, despite some epipelagic larvae. We undertook a near-bottom larval sampling programme on the upper continental slope (200-1000 m depth) of Suruga Bay, southern Japan, during monthly cruises of the T/V Hokuto(Tokai University). The ontogeny of alepocephalids (Leptoderma lubricumand L. retropinnum), liparids (Paraliparis dipterous) and macrourids (Coelorinchus kishinouyei) were clarified. Three distribution patterns of deep-sea demersal fishes related to the water column were determined. Illustration of three types based on ontogeny of near-bottom species on the upper continental slope of Suruga Bay was shown.
