Mitochondrial DNA A DNA Mapp Seq Anal. 2018 Jan;29(1):126-131. doi: 10.1080/24701394.2016.1253072. Epub 2017 Jan 10.
Catla (Catla catla) is a one of the most harvested Indian major carps and is widely cultured fish species in Indian subcontinent. In the present study, genetic variability between hatchery and wild stocks of Catla was surveyed using sequence data of mitochondrial DNA of partial 307 bp of cytochrome b region. A total of 174 Catla individuals were examined from three different river basins and hatcheries. Significant genetic heterogeneity was observed for the sequence data (F = 0.308, p ≤ 0.001). However, analysis of molecular variance (AMOVA) resulted in insignificant genetic differentiation among the samples of three rivers and culture zones (F = -0.10, p = 0.44). The result suggested a significant genetic variation within different riverine system, low genetic differentiation among samples from river basins and a lack of genetic variation in hatchery populations.
印度鲃（Catla catla）是印度主要养殖的鲤鱼品种之一，也是印度次大陆广泛养殖的鱼类。在本研究中，利用细胞色素b区域部分307bp的线粒体DNA序列数据，对印度鲃孵化场种群和野生种群之间的遗传变异性进行了调查。从三个不同的流域和孵化场共检测了174个印度鲃个体。序列数据显示出显著的遗传异质性（F = 0.308，p≤0.001）。然而，分子方差分析（AMOVA）结果表明，三条河流和养殖区样本之间的遗传分化不显著（F = -0.10，p = 0.44）。结果表明，不同河流系统内存在显著的遗传变异，流域样本间遗传分化较低，孵化场种群缺乏遗传变异。
