| Research Abstract |
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.
