“…Also, the higher migration rate of sea trout in the lower to mid Tweed compared to salmon suggests that they transited through the lower-mid Tweed faster and, therefore, were susceptible to capture for a shorter period than salmon. These results broadly agree with other research (Bagliniere et al, 1990(Bagliniere et al, , 1991Aarestrup & Jepsen, 1998;Svendsen et al, 2004;Finstad et al, 2005;Ö stergren et al, 2011), with slowing in migration speed being due to switching between migration phases (Økland et al, 2001;Finstad et al, 2005). The markedly reduced migration rate within tributaries may also suggest why earlier migrants penetrate further into catchments (Ö stergren et al, 2011), but also highlights the effects of river flow at this stage of migration (Webb, 1989;Thorstad & Heggberget, 1998;Svendsen et al, 2004).…”

“…Laughton & Smith, 1992). Atlantic salmon and sea trout migration after river entry comprises several behavioural stages: the migration stage, the searching stage and the holding stage (Hawkins & Smith, 1986;Bagliniere et al, 1990;Økland et al, 2001;Thorstad et al, 2008). The initial migration stage is when most upriver movement occurs and can last from a week to over a month, with the duration of the stage depending on migration distance (Økland et al, 2001;Finstad et al, 2005;Bendall et al, 2012).…”

River Tweed, UK, using acoustic telemetry to complement exploitation rate data and to quantify 17 catchment penetration. Salmon (n=79) and sea trout (n=65) were tagged in the tidal Tweed in 18 summer-autumn. No tagged salmon left the river before spawning, but 3% (2010) and 8% (2011) of 19 pre-spawning sea trout dropped out. Combined tag-regurgitation/fish mortality in salmon was 20 12.5%, while trout mortality was 6% (2010) and 0% (2011). The estimated spawning positions of 21 salmon and sea trout differed; tagged salmon were mostly in the main channel while trout occurred 22 mostly in the upper Tweed and tributaries. Early fish migrated upstream slower than later fish, but 23 sea trout moved through the lower-middle river more quickly than salmon, partly supporting the 24 hypothesis that the lower exploitation rate of trout (1%, vs 3.3% for salmon) there is by differences 25 in migration behaviour. This study illustrates the utility of telemetry in exploring differences in 26 catchment use and exploitation patterns of multiple stocks.

“…Alabaster (1970) noted that more Atlantic salmon and sea trout pass through traps on rising water levels than on steady or receding levels. In contrast, MacCrimmon & Gordon (1981) and Bagliniere et al (1990) found that rainbow trout, brown trout, and Atlantic salmon on spawning migrations moved more on the recession of a flood than on the rise. Flow in the Tongariro River responds relatively fast to rainfall making it difficult to determine precisely whether movement occurred during the rise or fall of a flood.…”

“…Fast rates of upstream travel have been reported for salmonids through estuaries and the lower reaches of long rivers (Hawkins & Smith 1986;Heggberget et al 1988;Glova & Washbourne 1990) and during the first 10 days after entering the river (Heggberget et al 1996). As salmonids travel further up stream, movement slows down (Heggberget et al 1996) and is more erratic especially a few days before spawning (Bagliniere et al 1990). The stretch of the Tongariro River accessible to spawning fish is short in comparison to those where the above studies were carried out.…”

The movements of 74 rainbow trout (Oncorhynchus mykiss) were monitored every 2-3 days using radio-telemetry during the spawning migration up the Tongariro River, New Zealand, between June and November 1995. Contrary to the views of anglers, movements of individual fish were highly variable and upstream movement could not be predicted from environmental conditions and fish related variables (length, sex, and reproductive status). There was no significant difference in individual movement between male and female fish. When individual movements were in an upstream direction, maiden trout moved faster, but less often, than fish that had spawned in previous years. The flow in the lower river explained 9% of the variance in individual downstream movements. Net upstream movement occurred throughout most of the study period with above mean activity when the river was in spate, especially early in the migration season when fish responded to flow changes as low as 7%. Above mean upstream daily movement occurred 8 times on rising and 9 times on falling barometric pressure. Large floods caused downstream displacements, but fish tended to move up stream again on the flow recession. The most noticeable downstream movement occurred following the eruption of Mount Ruapehu.

In regulated rivers, canalization and reduced water discharge may lead to loss or impairment of salmonid spawning areas, and thereby negative effects on stock recruitment. We discuss the possibility of mitigating such effects through establishing new spawning areas by addition of gravel. We monitored the occurrence of nests in seven gravel deposition sites in five different Norwegian rivers. The total area covered by each of the depositions spanned from 25 m 2 to 300 m 2 . The areas were examined for nests during a 2-5 year period following the addition of gravel, that is, a total of 27 spawning periods. The fish were found to spawn at all localities and years with the exception of two occasions when gravel was lost during floods. Spawning success measured as egg survival was generally high (>80%). These results show that the additions met the criteria for successful spawning. Nests of Atlantic salmon were found to be aggregated in the area with the highest water current. However, successful nests were also found in areas with added gravel where the water current was much reduced. This unusual selection of spawning site most likely reflects the lack of other, more favourable spawning areas. The results therefore suggest that gravel additions can be successful even if the only available areas are suboptimal with respect to water flow and water depth. Three of the seven localities were unsuitable as the gravel was partly or totally displaced downstream during floods. At two of these localities, nests were probably lost because the floods occurred after the spawning season. This shows that large floods can be a major drawback. Monitoring of the spawning success and displacement of gravel is therefore essential to evaluate the method. Subsequently, stable areas, favoured by the spawners, can be expanded by supplementary addition of gravel. In sum, the results show that the careful addition of gravel areas can be used to provide suitable spawning locations for salmonids in regulated rivers.
