Abstract:

对2009年和2011年采自荣成湾的孔鳐(Rajaporosa)群体共54尾鱼的线粒体DNA细胞色素b基因(cytb)部分序列进行测定,以分析其遗传多样性和群体遗传结构。结果显示,在所获得的782bp序列中,共检测到11个单倍型、15个多态位点,其单倍型多样性指数(H)为0.498±0.081,核苷酸多样性指数(π)为0.0018±0.0005,遗传多样性水平较低。其中,2009年样品检测到3种单倍型、4个单一变异位点,其H和π值分别为0.378±0.181和0.0010±0.0006;2011年样品检测到9种单倍型、6个单一变异位点和6个简约信息位点,其H和π值分别为0.352±0.086和0.0020±0.0006。分子方差分析(AMOVA)分析显示它们的遗传变异主要集中在同年度个体间(98.22%),而不同年度个体间的遗传变异远远小于同年度内个体间的变异。Kimura’s2-parameter模型分析得到的2009,2011年度孔鳐间的遗传距离为0.0013,遗传分化系数为0.01778,也表明2009年和2011年孔鳐的遗传分化程度低,没有明显的遗传变异。中性检验表明,荣成湾孔鳐群体可能发生过种群扩张。
