Contrasting population and life history responses of a young morph-pair of European whitefish to the invasion of a specialised coregonid competitor, vendace.

However, there was a significant negative correlation between vendace pelagic CPUE and condition factor residuals in DR-whitefish one year later (r Pearson = 0.51, P = 0.026), a nearly significant negative correlation between vendace CPUE and vendace condition factor residuals the year after (r Pearson = 0.44, P = 0.060), but no correlation between vendace CPUE and SR whitefish condition factor residuals (r Pearson = 0.12, P = 0.81).
