Overview of origin of samples used in phylogenetic analyses.

The final alignment comprised PRV protein coding sequences S1, S2 and S4 from sea-trout, wild, hatchery-reared and farmed Atlantic salmon.*From Etne; believed to come from the same aquaculture site.本最终序列联配结果包含PRV蛋白编码序列S1、S2及S4，序列来源涵盖海鳟、野生大西洋鲑、孵化场繁育大西洋鲑及养殖大西洋鲑。* 样本采自埃特讷（Etne）；据信源自同一水产养殖场地。
