Abstract
The date of fry emergence over 30 years in a sea trout nursery stream, predicted by an individual-based model, correlated significantly
(r=0.660, P<0.001) with an index of the North Atlantic Oscillation.
Water temperature is the main driving variable in the model and stream
temperature also correlated significantly (r=0.662, P<0.001) with the
index, providing a probable causal link. Therefore, the inter-annual
variations in emergence may not be unique to this one stream, but may be
typical of other trout streams with similar climatic conditions. (C)
