  1. The rankings are calculated by NormFinder (N), geNorm (G), BestKeeper (B). A ranking of 1 is considered the best candidate, while 6 is listed as the worst. Abbreviations: Dev1 - developmental stages before activation of zygotic transcription, Dev2 - developmental stages after hatching, A. kidney - anterior kidney, Mock - mock-injected, NNV - NNV-injected.
