“…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).…”

“…During this period fish tend to sustain constant upstream movement rates, regardless of flow and time of day. Stepwise upstream movements begin after the first stop, after which movement is usually but not always restricted to crepuscular and nocturnal periods (Webb, 1989;Laughton, 1989;Webb, 1990;Bagliniere et al, 1991;Kennedy et al, 2013). The number of halts in migration progress tends to increase with migration distance (Økland et al, 2001).…”

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.

“…070 -48.700 MHz (1995) and48.674 -48.764 MHz (1999). The 48 MHz frequency range is commonly used in rivers because of relatively low signal attenuation (Baglinière et al, 1991). These tags are detectable in brackish water, although not useful in the ocean because detection distances decrease with increasing conductivity (salinity) (Shroyer and Logsdon, 2009).…”

ABSTRACT. Radio telemetry and t-bar tagging were used to locate sites used by Hornaday River Arctic char (Salvelinus alpinus) for overwintering, spawning, and summer feeding. Thirty char, 21 in August 1995 and nine in July and August 1999, were captured, radio-tagged, and released back into the Hornaday River. Tracking was done over 14 months in 1995 -96 and over three months in 1999, using either aircraft (10 flights) or snowmobiles traveling on the river ice in winter (7 trips). Of 12 radio-tagged char that were relocated during winter 1995 -96 and not caught in the 1995 upstream migration fall fishery, 11 (92%) ultimately overwintered in the reach of the Hornaday between Coalmine and Akluk Creek; three of these did so in consecutive years. This area is characterized by groundwater inputs and deep pools (> 2 m) that do not freeze to the riverbed in winter. Another important overwintering site was found in a similarly deep channel on the west side of the Hornaday River estuary, where half of the char radio-tagged in fall 1999 spent the winter of 1999 -2000. Spawning locations were discerned through circumstantial evidence from the movements of three radio-tagged fish over entire annual cycles. The locations that were indicated as spawning habitat were all in the main stem of the Hornaday River, in deep (> 2 m), groundwater-fed pools between Coalmine and Akluk Creek. Fourteen percent of 239 char t-bar tagged at Pearce Point in July -August 1997 were caught at the mouth of the Hornaday River, on average within 25 days of tagging, which indicates that the nearshore area of Pearce Point, characterized by upwelling and enhanced productivity, is an important summer feeding area for this stock. This identification of overwintering, spawning, and summer feeding habitats contributes to an emerging list of areas for which it would be prudent to monitor habitat quality, change, and integrity given contemporary changes in climate and the potential for near-future anthropogenic activities in this watershed.Key words: Arctic char, Hornaday River, Salvelinus alpinus, migration, Northwest Territories, overwintering, spawning, summer feeding, tagging RÉSUMÉ. La radiotélémesure et les étiquettes en T ont été employées pour repérer les lieux utilisés par l'omble chevalier (Salvelinus alpinus) de la rivière Hornaday pour l'hivernage, le frai et l'alimentation estivale. Trente ombles ont été capturés dans la rivière Hornaday, soit 21 en août 1995 et neuf en juillet et en août 1999. Des radio-émetteurs ont été posés sur ces ombles, après quoi ils ont été relâchés dans la rivière. Nous les avons suivis pendant 14 mois en 1995-1996 ainsi que pendant trois mois en 1999, en avion (dix vols) ou en motoneige sur la glace de la rivière pendant l'hiver (sept expéditions). Parmi les 12 ombles dotés de radio-émetteurs qui ont été relocalisés à l'hiver 1995-1996 et n'ont pas été attrapés pendant la pêche de la montaison automnale en 1995, 11 (92 %) ont fini par passer l'hiver dans le passage de la Hornaday situé entre Coalmine et le ruisseau A...
