… trouts from the lower part of the rivers to their spawning sites in the rivers Vindelälven and Piteälven. A knowledge about the distribution of spawning sites in the rivers will help these fish population in future restoration programs. In the fishladder at Norrfors in the river …
början till slutet på den svenska vattenkraftsutbyggnadesepoken
… och utbyggnadsintressena kulminerade vid 1960-talets slut i striden om Vindelälven. Den kom att markera början till slutet för den svenska vattenkraftsutbyggnadsepoken Hur avgörande denna på naturskydds- och forskningsintressen grundade motståndsopinion var för den fortsatta …
En detaljerad landformkartering av ett högfjällsområde i Vindelälvens källområde har utförts med syfte att öka kunskapen om inlandsisens dynamik och karaktär (iskantens reträtt, isens aktivitet och rörelseriktningar och isens basala temperatur) under deglaciationen i denna del …
a case study in tributaries to river Vindelälven, northern Sweden
… models are applied to spawning beds in restored tributaries to river Vindelälven. I evaluate these as a method to determine suitable locations for construction of spawning beds. I also evaluate erosion of constructed spawning beds attributable to spawning activities by female …
upstream and downstream migration of Atlantic salmon (Salmo salar) in the northern Swedish river Vindelälven
… cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass …
Habitat selection of migratory brown trout at the upper reaches of River Vindelälven, wasstudied in September during the pre-spawning period. The fish migrate from down- orupriver lakes for spawning in the river and data was collected by habitat mapping andradio-telemetry …
consequences of using different density estimation methods
Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of …
… past the VAKI-system, there seems to be no problem for the fish to reach river Vindelälven. I also report that the migration pattern passed the fish way did not differ between native salmons from the Ume/Vindelälven stock and strayers with a genetic origin from the Luleälven …
During the timber floating era, most of Sweden’s watercourses were altered. This decreased the amount of available spawning habitats for salmonids, and hence had a negative effect on the riverine brown trout (Salmo trutta) populations. Reconstruction of spawning grounds is today …
