尽管对野生和圈养鳗鱼进行了深入的研究，但迄今为止还没有任何资源可以提供日本鳗鱼所有生命周期阶段的信息。因此，从preleptocephalus（新孵化的幼虫）到leptocephalus阶段（典型的叶状鳗鱼幼虫）的过渡仍然是鳗鱼生命周期中缺失的一环。我们最近发现，由鲨鱼卵粉制成的浆状饲料是适合人工养殖鳗鱼幼鱼的饲料。在水族箱中用这种饲料成功地饲养了幼虫100天，并将其全长（TL）提高到22.8 mm。年龄，TL。饲养标本的体比例与野生标本的体比例重叠。我们首次揭示了鳗鱼从preleptocephalus到leptocephalus阶段的过渡。(C)2001 Elsevier Science B.V.保留所有权利。
Despite intensive research on wild and captive eels, no resource has so far provided access to all life cycle stages of the Japanese eel Anguilla japonica. The transition from the preleptocephalus (newly hatched larva) to the leptocephalus stage (typical leaf-like eel larva) has, therefore, remained the missing link in the eel life cycle. We recently found that a slurry-type diet made from shark egg powder is suitable feed for captive-bred eel larvae. The larvae were successfully reared with this diet in aquaria for 100 days and raised to 22.8 mm in total length (TL). Age, TL. and body proportions of the reared specimens overlapped with those of wild leptocephali. We revealed for the first time the transition from the preleptocephalus to the leptocephalus stage of the eel. (C) 2001 Elsevier Science B.V. All rights reserved.
