ABSTRACT

The Greater Lizardfish, Saurida tumbil, forms a significant fishery in the demersal trawls along the west coast of India. But, the information regarding the stock structure of this species is scarce. In the present study, the morphology of fish, otolith shape, meristic traits and mt-DNA D-loop region were used to delineate the stocks collected from the west coast of India. Samples were collected between October to November 2018 from three major fish landing centres namely Mumbai, Mormugao and Kochi. Truss network analysis and otolith shape indices revealed the morphological divergence for body and otolith shape among the sampling regions. However, meristic traits and D-loop sequences of mitochondrial DNA could not show variation among the stocks, suggesting the existence of a single panmictic population of S. tumbil. The results of the present study are useful to formulate the stock-specific management measures for S. tumbil along the west coast of India.

使用形态学和分子标记对印度西海岸大蜥蜴鱼、蜥蜴鱼 (Bloch, 1795) 的种群特征进行表征

摘要

大蜥蜴鱼Saurida tumbil在印度西海岸的底层拖网中形成了重要的渔业。但是,关于该物种种群结构的信息很少。在本研究中,鱼类的形态、耳石形状、分生性状和 mt-DNA D-loop 区域被用来描绘从印度西海岸收集的种群。样本是在 2018 年 10 月至 11 月期间从孟买、莫穆高和高知这三个主要鱼类登陆中心收集的。桁架网络分析和耳石形状指数揭示了采样区域之间身体和耳石形状的形态差异。然而,线粒体 DNA 的分生性状和 D-loop 序列不能显示种群之间的变异,表明存在单一的大流行种群S. 翻滚。本研究的结果有助于制定印度西海岸S. tumbil的种群特定管理措施。
