项目摘要

Triggerfishes of the family Balistidae are found mainly in tropical regions in the Indo-Pacific and Atlantic. The Balistidae are composed of 11 genera and 30 species. Systematic studies of this family were made by Matsuura (19780) and phylogenetic relationships were published by Matsuura (1979) and Tyler (1980). There remaine no large problems in the taxonomy of adult triggerfishes. However, as in many cases of other teleostean fishes, larvae of triggerfishes are difficult to be identified to species or even to generic level because it is not easy to obtain adequate materials including series from early developmental stage to young. Thus, the main purpose of this study is to describe diagnostic characters of triggerfish larvae based on many individuals being now available at museums and fisheries institutions.The detailed examinations of many triggerfish larvae and adults led to a conclusion that they can be identified by using combinations of meristic characters of dorsal-fin rays, anal-fin rays, pectoral-fin rays, longitudinal scale rows, and head scales. In many cases color patterns of larvae and young are helpful to identify them to generic level and frequently to species level. Osteological examinations of larvae and adults show that the genus Xenobalistes is first separated phylogenetically from all other genera. In the remaining 10 genera, Canthidermis is differentiated from the others, then Xanthichthys, Rhinecanthus, and Balistapus are separated from the others. The most derived genus is considered to be Abalistes.

鳞鲀科的触发鱼主要分布在印度洋-太平洋和大西洋的热带地区。Balistidae由11属30种组成。Matsuura（1978）对该科进行了系统学研究，Matsuura（1979）和泰勒（1980）发表了系统发育关系。在成鱼的分类上没有大的问题。然而，在许多情况下，其他硬骨鱼类，鱼的幼虫是很难确定的种，甚至属的水平，因为它不容易获得足够的材料，包括从早期发育阶段到年轻的系列。因此，本研究的主要目的是描述的诊断特征的基础上，许多个体，现在可在博物馆和渔业institutions.The详细的检查，许多的幼鱼和成年人，导致的结论是，他们可以通过使用的组合的meristic特征的背鳍射线，肛鳍射线，胸鳍射线，纵向鳞片行，和头部鳞片。在许多情况下，幼虫和幼仔的颜色模式有助于在属的水平上识别它们，通常也有助于在种的水平上识别它们。幼体和成虫的骨骼学检查表明，异石属首先从所有其他属中分离出来。在其余10属中，尖皮鱼属与其它属相区别，其次是黄鱼属、鼻棘鱼属和锯鳞鱼属。最具衍生性的属被认为是Abalistes。
