自世纪中期网箱养殖技术问世以来，大量人工养殖真鲷及其配子从网箱养殖中逃逸并扩散到野外。这些逃脱者可能被招募到野生种群中，影响了它们的遗传多样性。在这项研究中，我们使用微卫星标记的分配方法，以评估逃逸养殖的红鲷在一个主要的水产养殖生产区（UWJ）和两个地区相对较低的产量（IWG和SIJ）在日本爱媛县的野生种群的频率。在UWJ越狱的频率范围从14.1%到30.2%，所示的三种分配方法。在钓鱼捕获的标本中，经常发现逃跑者（从26.7%到46.7%不等），这表明他们即使在逃跑后也会留在同一地区，或者比野生个体更不谨慎。在水产养殖不太广泛的IWG和SIJ地区没有发现逃逸者。一些野生捕捞的鱼类似乎与养殖鱼类杂交，通过模拟获得的隶属系数的阈值所示。这些结果清楚地表明，大量的养殖个体逃离了UWJ，一个主要的水产养殖区，因为在日本的红鲷养殖开始。野生和养殖个体杂交后可能会发生基因重组。
A large number of farmed red sea bream (Pagrus major) and their gametes have escaped and dispersed into the wild from net-cage aquaculture since the advent of the technology in the mid-20th century. These escapees have likely been recruited into wild populations, affecting their genetic diversity. In this study, we used assignment methods with microsatellite markers to assess the frequency of escapee farmed red sea bream within the wild populations in a major aquaculture production region (UWJ) and in two regions with relatively lower production (IWG and SIJ) in Ehime Prefecture, Japan. The frequency of escapees in UWJ ranged from 14.1% to 30.2%, as shown by three methods of assignment. Escapees were frequently identified among specimens caught by angling (ranging from 26.7% to 46.7%), suggesting that they stay in the same area even after escape or are less cautious than wild individuals. No escapee was found in IWG and SIJ, areas with less extensive aquaculture. Some wild-caught fish appeared to have hybridized with farmed fish, as indicated by the threshold of membership coefficients obtained by simulation. These results clearly indicate that large numbers of farmed individuals have escaped from UWJ, a major aquaculture area, since the inception of red sea bream farming in Japan. Genetic reshuffle has possibly occurred following hybridization of wild and farmed individuals.
