Genetic introgression from stocked adult northern pike Esox lucius to a wild self-recruiting population was detected in a large river system and some stocked E. lucius survived up to two spawning seasons and dispersed over several kilometres in the river. Moreover, the catch rate of stocked E. lucius by anglers was low (9.6%), hence suggesting that the efficiency of stocking activity is questionable.
在一个大型河流系统中检测到，放流的成年北方狗鱼（Esox lucius）与野生自我繁殖种群之间存在基因渗入，并且一些放流的北方狗鱼存活了两个产卵季节，并在河流中扩散了数公里。此外，垂钓者捕获放流北方狗鱼的比例较低（9.6%），因此表明放流活动的效率值得怀疑。
