【摘要】 革鲀科的鳞片构造不同于一般真骨鱼类的骨鳞,由特化的基板和鳞棘两部分组成。中国有革鲀科鱼类12属19种,本文研究了其中10属14种的鳞片构造,运用扫描电镜进行了观察和比较。根据基板表面棱突的特征,可将革鲀科基板构造分为3个式型、2个亚型;根据鳞棘数目、形状及排列方式的不同,可以划分为4个式型。革鲀科各种间的鳞片具有不同的性状,而且比较稳定,因此可以作为分类鉴定的依据之一。更多还原

【Abstract】 The present paper deal with the comparative studies of morphology of scales of Aluteridae under the scanning electron microscope. Fourteen species of Chinese aluteridae fishes, belong to 10 genera, were investigated. The characteristics of the scales of Aluteridae are more different with the scales of other Teleostei. The scale consists of basal plate and scale spine, and have not the characteristics of focus, circulus and radii which found in most Teleostei. According to the differences of the surface structure of the basal plate, they may be divided into 3 patterns: (1) radiant pattern (Stephanolepis citrhifer, Chaetodermis spinosissimus, Arotrolepis sulcatus, Monacanthus chinensis and Alutera scripta); (2) branch-shaped pattern, it consists of 2 subpatterns: A. fork-shaped subpattern (Paramonacanthus oblongus, Paramonaconthus nippo-nensis, Navodon sp. and Alutera monoceros), B. paralled-shaped subpattern (Navodon septentri-onalis, Navodon tessellatus and Cantherhines dumerilii); (3) Honeycomb-shaped pattern (Per-vagor melanocephalus and Oxymonacanthus longirostris).According to the differences in number and range of the scale spine, they may be divided into 4 patterns: (1) singlespine pattern (Arotrolepis sulcatus, Monocanthus chinensis and Alutera scripta); (2) poly-spines and single-line pattern (Oxymonacanthuslongirostris and Navodon sp.) ; (3) poly-spines and poly-lines pattern (Paramonacanthus nipponensis, Paramonacanthus oblongus, Navodon septentrionalis, Navodon tessellatus, Cantherhines dumerilii and Alutera mo-noceros); (4) poly-spines and base-merged pattern (Stephanolepis cirrhifer, Chaetodermis spi-nosissimus and Pervagor melanocephalus).Because of the morphological characteristics of scales are noticeably different among the separating species, it can be used as the taxonomic characteristic in Aluteridae.更多还原
