| 摘要: |
| 石首鱼类是我国海洋鱼类中具有代表性的类群之一，通常栖息于泥沙底质的浅海，一般不作远距离回游，有些种类(如大黄鱼和小黄鱼)数量多、鱼群大，是重要的经济鱼类。浙江外海是我国最重要的海洋渔业生产区，探讨石首鱼类在这一海区的分布相季节变化，对渔业生产和鱼类区系研究都有现实意义。本文根据在浙江近海调查所取得的11种石首鱼类［大黄鱼Pseudosciaena crocea (Richardson), 小黄鱼Pseudosciaena polyactis (Bleeker,)鮸鱼Miichthys miiuy (Basilewsky), 棘头梅童鱼Collichthys lucidus (Richardson), 黑姑鱼Atrobucca nibe (Jordan et Thompson), 叫姑鱼Johnius belengerii (Cuvier et Valenciennes),丁氏?Wak tingi (Tang), 白姑鱼Argyosomus argentatus (Houttuyn), 大头白姑鱼Argyrosomus macrocephalus (Tang), 黄姑鱼Nibea albiflora (Richardson), 双棘黄姑鱼Nibea diacanthus (Lacépède)] 的周年性资料，对此进行了分析和研究。 |

| Abstract: |
| The present paper is a result of a study on the seasonal distribution of Sciaenoid fishes, which arc the interesting material for fish fauna study, and some of them are the most irnportont food fishes in China.
Monthly samples of Sciaenoid fish, Pseudosciaena crocea, P. polyactis, Miichthys miiuy, Collichtys lucidus, Atrobucca nibe, Johnius belengerii, Wak tingi, Nibea albiflora, N. diacanthus, Argyrosomus argentatus,A. macrocephalus, were caught with double draggers from 45 different locations at Lat. 27°30'N to 31°30'N in marine sanctuaries off Zhejiang during March 1960—Febuary 1961.
Total annual catch of 11 species of Sciaenoid fishes makes up about 33% of the total catch of 220 species.
Catches of all these Sciaenoicl fishes have ,a seasonal variation in this area, some of them owing to spawning migration were high in spring and low in winter, such as Pseudosciaena crocea, P. polyactis, Miichthys miiuy etc.
The seasonal change of sea water temperature is reflected on the seasonal change in species number and abundance of the Sciaenoid fishes, such as Atrobucca nibe,Nibea diacanthus, Wak tingi etc. |
