The partial sequences of cytochrome c oxidase subunit I (COI) mitochondrial gene were analysed for developing species specific molecular signatures and phylogenetic relationship among the commercially important flying fishes (Cheilopogon cyanopterus, Cheilopogon furcatus and Hirundichthys coromandelensis) distributed in Tamil Nadu coast. Accurate identification of these species is important for fishery management as its morphological characters are very similar. Since the morphological features are very similar, accurate identification using molecular tools is essential for sustainable utilization and management of these species across their distributional range. The estimated transition/transversion bias (R) is 3.45. The average nucleotide sequences calculated were A = 30.00%, T/U = 26.40%, C = 17.00% and G = 26.60%. Using COI data analysis, the intraspecies genetic distance ranged from 0.00 to 0.05, while it varied from 0.06 to 0.08 for interspecies. Partial sequences of the genes provided sufficient phylogenetic information to distinguish the three flying fishes indicating the usefulness of mtDNA-based approach in species identification.

泰米尔纳德邦海岸飞鱼的分子鉴定和系统发育关系,用于渔业管理。

细胞色素C氧化酶亚基I(COI)线粒体基因的部分序列进行分析用于开发商业上重要的飞行鱼类间特定物种的分子签名和亲缘关系(Cheilopogon cyanopterusCheilopogon furcatusHirundichthys coromandelensis)分布在泰米尔纳德邦海岸。由于其形态特征非常相似,因此准确识别这些物种对于渔业管理非常重要。由于形态特征非常相似,因此使用分子工具进行准确鉴定对于这些物种在其分布范围内的可持续利用和管理至关重要。估计的转换/转换偏差(R)为3.45。计算的平均核苷酸序列为A = 30.00%,T / U = 26.40%,C = 17.00%和G = 26.60%。使用COI数据分析,种内遗传距离在0.00到0.05之间,而种间遗传距离在0.06到0.08之间。基因的部分序列提供了足够的系统发育信息,以区分三种飞鱼,表明基于mtDNA的方法在物种识别中的有用性。
