| 摘要: |
| 1975-1976年“金星”号调査船在东海陆架区先后进行了三个航次的调查,曾采到灯笼鱼科中的六个属七个种的后期仔鱼共646尾。它们是无须灯笼鱼Diogenichthys panurgus Bolin,粗鳞灯笼鱼Myctophum asperum ( Richardson),巴氏灯笼鱼Gonichthys barnesi Whitely,神鰯灯笼鱼Diaphus theta ( Eigenmann et Eigenman),多光灯笼鱼Ceratoscopelus townsendi ( Eigenmann et Eigenmann),柳氏戴芬鱼Diaphus lutkeni Brauer及七星鱼Benthosema pterota ( Alcock)。在我国海域,除七星鱼的成鱼和神鰯戴芬鱼的后期仔鱼与稚鱼有过记录外,其它各种,包括其早期变态时期的后期仔鱼皆系首次记录。
灯笼鱼科的鱼类广布于热带和亚热带水深200-500米的大洋中层水域,是大洋性重要经济鱼类和海洋哺乳动物的重要饵料的组成部分。对灯笼鱼科鱼类的后期仔鱼及稚鱼的分布和形态的研究,对进一步探讨成鱼的生态及其地理分布有着重要的意义。
本文就七种灯笼鱼的后期仔鱼的出现及其变态时期的特征进行研讨。 |

| Abstract: |
| The post-larvae of the lanternfish were collected during 1975-1976 by the R/V“Jinxing”'from the continental shelf of the East China Sea.
This report deals with the distribution and morphology of the post-larvae of 7 species of Myctophidae. They are Diogenichthys panurgus Bolin,Myctophum asperum (Richardson) Gonichthys barnesi Whitely, Diaphus theta (Eigenmann et Bigenmann),Diphus lutkeni Brauer, Ceratoscopelus, townsendi (Eigenmann et Eigenmann) and Benthosema pterota (Alcoek). With the exception of Diaphus theta and Benthosem pterota the five others were never recorded before in Chinese waters.
A key for identification of the post-larvae is presented..
The occurrence of these fishes in the East China Sea, particularly Diogenichthys panurgus, Myctophum asperum, Gonichthys barnesi and Diaphus lutkeni are governed by the environmental changes, especially by fluctuation of the Kuroshio. |
