摘要1992年在斯卡格拉克海峡150-550 m深度范围内发现了两种丰富的浮游鱼类，即岩生类鱼和阿根廷长鳍鱼。鸡蛋C。仅在10月和12月发生，12月捕获一只卵黄囊幼虫。后期幼虫和少年发生在所有月份（2月，4月，6月，10月，12月），并表现出持续增长的长度通过一年。这证实了早期的迹象，一个单一的晚秋产卵期。到10月，幼鱼已经达到了底层生活方式。阿根廷细口螺卵和幼虫全年发生，但卵在春季最丰富。其他大部分鱼卵和幼鱼可能是在表层偶然捕获的。这可能是四条大西洋大比目鱼Hippoglossus doglossus L.
Abstract Two species, Coryphaenoides rupestris and Argentina silus, were abundant in the ichthyoplankton of the 150–550 m depth zone of the Skagerrak in 1992. Eggs of C. rupestris occurred only in October and December and a single yolk sac larva was caught in December. Postlarvae and juveniles occurred in all months (Feb, Apr, Jun, Oct, Dec) and showed a continuous increase in length through the year. This confirms earlier indications of a single late autumn spawning period. By October the juveniles had attained a demersal mode of life. Argentina silus eggs and larvae occurred year-round, but eggs were most abundant in the spring. Most of the other fish eggs and larvae were probably caught incidentally in surface layers. Exceptions may be four postlarval Atlantic halibut Hippoglossus hippoglossus L.
