Example text

The timing of gravel emergence is one of the major ‘bottlenecks’ in the salmon life-history, as an absence of suitable food at the time of emergence will lead to starvation. Therefore, the spawning time in each river is adjusted so that the fry will hatch at the most favourable time (Heggberget 1988). After hatching, and depending on latitude, environmental conditions and genetics, the juveniles (parr) remain in fresh water for 1–8 years (Fig. e. smoltify) and migrate to the sea for feeding (Fig.

2007b). 53 body lengths per second for wild post-smolts). Based on studies in different coastal areas (Finstad et al. 2005; Thorstad et al. 2007b; Davidsen et al. 2009; Økland et al. unpublished results), postsmolts may spend from less than one week and up to four weeks passing Norwegian fjord systems (which are up to 200 km long), before entering the open ocean. Similarly, wild and hatchery-reared post-smolts quickly moved through Passamaquoddy Bay in North America, with most negotiating a distance of 23–36 km in 2–6 days (maximum 12 days, Lacroix et al.

Migration barriers, unusual migration patterns after stressful events or an avoidance response in an attempt to escape from unfavourable conditions may alter the distribution of the spawning population within the river. Salmon may, for instance, abandon their attempts to reach areas high in the watershed and instead spawn in lower reaches (Solomon et al. 4) or even leave the river. Juvenile survival is strongly density-dependent during the first months following emergence (Einum & Nislow 2005).
