The influence of climate at sea on S. salar growth has extensively been studied (e.g. Friedland, 1998; Friedland et al., 2000; Niemelä et al., 2004; Peyronnet et al., 2008). Sea surface temperatures at large scales and global indices such as the North Atlantic Oscillation Index have been observed to be correlated to individual growth. However, no mechanistic and fine scale processes have been identified yet. We opted consequently for representing a general oceanic environmental condition in IBASAM that influenced on growth through the NoiseSeat parameter (see Section 2.1.7.4, varying every day t). For simulations, this parameter is simply a normal random number centred on MeanNoiseSea=1 and of variance 0.1. In further studies with IBASAM assessing the effect of oceanic climate change, the MeanNoiseSea parameter can be easily made variable through time. |
