For sixteen years following the 1989 Exxon Valdez oil spill adult returns of pink salmon in Prince William Sound, Alaska were monitored to assess spill effects on survival. No evidence of spill effects was detected for either intertidal or whole-stream spawning fish. From 1989 through 2004 mean densities for oiled and reference streams tracked each other, illustrating similar responses of oiled and reference stream adult populations to naturally changing oceanographic and climactic conditions. Hatchery fish strayed into the study streams, but similar incursions occurred in oiled and reference streams, and their presence was compensated for to eliminate their influence on determining the success of the returning natural populations. These results, showing no detectable effects of oiling on pink salmon spawning populations, are supported by published field studies on pink salmon incubation success in oiled streams.
在1989年埃克森·瓦尔迪兹号油轮漏油事件发生后的16年里，对阿拉斯加威廉王子湾粉鲑的成年洄游情况进行了监测，以评估漏油对其生存的影响。对于潮间带产卵鱼和全溪流产卵鱼，均未检测到漏油影响的证据。从1989年到2004年，受油溪流和参考溪流的平均密度相互跟踪，表明受油溪流和参考溪流中的成年鱼种群对自然变化的海洋学和气候条件有类似的反应。孵化场的鱼误入研究溪流，但受油溪流和参考溪流中都发生了类似的侵入情况，并且对其存在进行了补偿，以消除它们对确定自然种群洄游成功与否的影响。这些结果表明，漏油对粉鲑产卵种群没有可检测到的影响，这得到了已发表的关于受油溪流中粉鲑孵化成功率的实地研究的支持。
