闽南-台湾浅滩渔场大头狗母鱼的早期发育及其与多齿蛇鲻的比较

STUDY ON THE EARLY DEVELOPMENT OF TRACHINOCEPHALUS MYOPS(BLOCH & SCHNEIDER) AND THEIR COMPARISON WITH SAURIDA TUMBIL(BLOCH & SCHNEIDER) IN THE FISHING GROUND OF THE SOUTHERN FUJIAN AND TAIWAN BANK

大头狗母鱼[Trachinocephalus myops(Bloch & Schneider)]为热带、亚热带近海常见的中下层鱼类,也是闽南-台湾浅滩渔场机帆船拖网周年均可捕获的主要对象之一。本文对大头狗母鱼鱼卵、前期仔鱼、后期仔鱼和稚鱼的形态特征作了描述和生物学测量。鉴于大头狗母鱼鱼卵和仔鱼与多齿蛇鲻的很相似,特将此鱼卵和仔鱼进行比较,以供今后资源调查参考,并为研究它们的生物学提供基本资料。一、材料与方法所用材料是闽南-台湾浅滩渔场鱼类资源调查队于1975—77年间采集的。

This paper describes in detail the early developmental stages of Trachinocephalus myops(Bloch&Schneider)and presents a list to show the comparison between Trachinocephalus myops(B.&S.)and Saurida tumbil(B.&S.)in order to facilitate the identification during research of fishery resources.About 400 eggs and 100 larvae of Trachinocephalus myops(B.&S.)and Saurida tumbil(B.&S.)were collected and observed from the fishing ground of the Southern Fujian and Taiwan Bank in the years between 1975-1977.
