Catch statistics 2010
The salmon rod fishery in Icelandic rivers in 2010 was the second highest recorded. Previously only 2008 have given higher catch in rod fisheries. In total 74.961 salmon were caught in rod fisheries in Icelandic rivers in 2010 where of 21.476 (28,6%) was released and the catch landed (caught and retained) was 53.485 salmon. The catch landed by weight was 142.542 kg. In the rod fishery the catch of grilse (1SW) were 58.643 fish (84,5%) and 111.831 kg and 10.745 salmon (MSW) (15,5%) weighing 30.693 kg. Of the total number of released fish 16.221 (75,5%) were grilse and 6.861 (24,5 %) salmon.
The salmon rod catch in 2010 increased by 533 fish (0,7%) from the 2009 salmon season. The total rod catch in 2010 was 51,9% higher than the average catch in the 36 years period from 1974 to 2009. The salmon catch in the net fishery was 6.296 fish (65,5%) higher than the catch in 2009 and 24% higher than the average catch in the period from 1974-2009.
The catch in the net fishery was 15.903 fish and 47.214 kg in total. Of the net catch 11.349 fish was grilse (1SW) weighing 27.674 kg) and 4.554 salmon (MSW) weighing 19.540 kg.
The total combined salmon catch landed (rod and nets) in Iceland 2010 was 69.388 fish and 189.738 kg, there of 58.643 (84,5%) were 1SW and 10.745 (15,5%) MSW. The total 1SW catch was 139.505 kg and the MSW catch was 50.223 kg.
The total number of brown trout caught in rod fishery was 48.798 fish, 7.841 were released and the catch landed was 40.957 fish and 47.154 kg. The total number of Arctic charr in the rod fishery was 33.514 fish, 2.397 were released and the catch landed was 31.117 fish and 23.374 kg.
In 2010 the rod catch in rivers where the catch is mainly based on releases of hatchery reared smolts was 17.911 fish that is 23,9% of the total catch and the catch was close to 42 tonnes. The rod catch of wild salmon in 2010 was 57.050 fish that was the highest recorded catch of wild salmon caught in rod fishery (Table 5, figure 3). In total 28,6% of the salmon rod catches was released and 35,5% of the wild salmon was released in the rod fishery.

Recovery of nursery area for salmon and trout in the river Elliðaá, Reykjavík
|From Austurkvísl branch, that was dry part of the year before 1999 but has been recovered since.|
Since the beginning of the 20th century the river Elliðaá and its biota has been under considerable human impact. Electric power plant, built in the river in 1921, caused part of the river system to dry up whereas the water level rose in other parts. This had consequences for the aquatic organisims. It has been estimated that the construction of the plant had direct impact on 43% of the wetted area. The most obvious influence was below the dam Árbæjarstífla on the two branches of the river, called Vesturkvísl and Austurkvísl, which used to flow below the dam. In the year 1999 the flow regime of the river was changed to maintain a minimal water flow in these two branches all year around. In the following years a research project was started to regain the biota in the area, with emphasize on Atlantic salmon juveniles. Salmon fry were stocked in the former dry areas. A year later the salmon juveniles were surveyed. The stocked fry had good survival and growth. Naturally hatched young-of-the-year was found at same sites as the stocked fry. Ten years later the density of the salmon juveniles are the same as in the undisturbed areas of the river. The recovered areas are estimated to be 15% of the producing river bed.

Seal research in Hvammstangi
Since 2009 the Institute of Freshwater Fisheries has developed a project in collaboration with The Icelandic Seal Center. The main objective of the project is to analyze predation patterns of harbor seals (Phoca vitulina) hauling out in river mouths and to estimate the impact of seals on salmonids.

Knowledge on what impact seals may have on salmonids is scarce and this is the first study of its kind being conducted in Iceland. The main research location of the project is at the estuaries Bjargós and Sigríðarstaðaós in the NW coast of Iceland, where the salmon rivers Víðidalsá, Fitjá and Gljúfurá flow to the sea. During the summer months, the number of seals hauling out in this area can be as many as four hundred.
The project consists of several different parts, one including tagging seals with radio transmitters. The tagging takes place at the end of June while the puppies being weaned by their mothers. The tags are glued on the back of the head of the seals and the transmitters are carried by the seals until next autumn. The signals from tagged seals are then received by special listening station situated between the two estuaries. Tagged seals are also positioned regularly by a mobile station. With this method the movement of the seals can be tracked and the time of stay at the estuaries can be measured, as well as how long they stay each time.
Five seals were tagged in 2010 and the collected information is still in prosessing phase. The aim is to tag around 15 individuals this summer.
More information are available in Icelandic on the website here and here. The project manager is Sandra M. Granquist.

Statistics from Icelandic rivers for 2006 available
Statistics from Icelandic rivers for the 2006 fishing season have been processed and the main results are summarized in this english-version (pdf-file) of an annual report. This work is based on Gudbergsson (2007), Lax- og silungsveiðin 2006, a report from the Institute of Freshwater Fisheries (in Icelandic). Statistics have been compiled this way since 1974. Some older reports are available here.

The fourth salmon recaptured with DST micro
The Institute of Freshwater Fisheries in Iceland recaptured their fourth salmon with DST micro, on Friday September 1st. The recapture took place at the release site in River Kidafellsá. The salmon was one of the 300 tagged salmon smolts that were released in the spring of 2005. Three salmon had already been recaptured two weeks earlier, so total of four salmon have been recaptured this summer. The tag had recorded depth and temperature of the fish at one hour sampling interval during the whole migratory route of the fish, which was 15 months. All the recaptured DST micro tags never failed during the route, confirming the reliability of the tags. The data from the tag comply with data from previous tags recaptured two weeks earlier, although greater depth dives can be seen in this tag.
