Mangrove red snapper, Lutjanus argentimaculatus is a commercially important fish. The genetic stock structure of L. argentimaculatus from Indian waters was identified using mitochondrial ATPase 6 and ATPase 8, and cytochrome b (Cytb) genes. A 842 bp region of ATPase 6/8 genes and 1105 bp region of Cytb gene were amplified in 120 samples from six different locations along the Indian coast and obtained 58 and 66 haplotypes, respectively. The high haplotype and low nucleotide diversity values along with mismatch distribution, Tajima's D and Fu's F analysis suggested a genetic bottleneck events or founder effect, with subsequent population expansion in L. argentimaculatus. Coefficient of genetic differentiation (F) values was low and nonsignificant for both ATPase 6/8 gene and Cytb genes indicating low genetic differentiation in L. argentimaculatus which can be managed as a unit stock in Indian waters.
紫红笛鲷，又称千年笛鲷，是一种具有重要商业价值的鱼类。利用线粒体ATP酶6和ATP酶8以及细胞色素b（Cytb）基因，对来自印度海域的紫红笛鲷的遗传种群结构进行了鉴定。在沿着印度海岸六个不同地点采集的120个样本中，扩增出了842 bp的ATP酶6/8基因区域和1105 bp的Cytb基因区域，分别获得了58个和66个单倍型。单倍型和核苷酸多样性值较高，以及错配分布、 Tajima's D和Fu's F分析表明，紫红笛鲷存在遗传瓶颈事件或奠基者效应，随后种群扩张。ATP酶6/8基因和Cytb基因的遗传分化系数（F）值较低且不显著，表明紫红笛鲷的遗传分化较低，在印度海域可作为一个单位种群进行管理。
