The Tanafjord ( Tanafjorden   ( Norwegian ) , Deanuvuotna   ( Northern Sami ) , or Tenonvuono   ( Kven ) ) is a large fjord in Finnmark county, Norway . It is located in the municipalities of Tana , Gamvik , and Berlevåg . Its orientation is mainly north–south, reaching approximately 65 kilometres (40 mi) from the small village of Smalfjord in Tana Municipality in the south to the mouth of the fjord at the Barents Sea . The fjord separates the Nordkinn Peninsula ( Gamvik Municipality ) in the west from the Varanger Peninsula ( Berlevåg Municipality ) in the east.

29-593: The Tana River empties into the southern part of the fjord. There are several side fjords which branch off of the main Tanafjorden including the Hopsfjorden , Langfjorden , and Gulgofjorden . There are some settlements along the fjord, but they are all small and rather isolated. Settlements include the villages of Vestertana , Austertana , Trollfjorden , Skjånes , Nervei , and Store Molvik . Norwegian County Road 98 and Norwegian County Road 890 run along

58-646: A "fishing area". In July 2024, there was salmon fishing for two days on the Finnish side of the river - and only in two places; only one fish 30–65 cm in length. Earlier (2022), authorities in Norway and in Finland [did] not permit salmon fishing (in the river). In 2023, on Finland's side of the river, some permits would allow fishing of humpback salmon - and the methods for that would be drift netting and seine fishing. In 2020, 18,600 kilograms (41,000 lb)

87-481: A choice. Many of the pink salmon that are caught by bears in Alaska are transported away from the water into riparian areas and forests, and nutrients from the carcasses end up in plants and trees. Carcasses of pink salmon that successfully spawn decompose rapidly, and are colonized by aquatic invertebrates in the process. These resource subsidies to stream habitats can increase the growth of other salmonid species in

116-429: A redd or rede (Scandinavian word for "nest"), in the gravel of the stream bed, where she deposits her eggs . As she expels the eggs, she is approached by one or more males, which fertilize them as they fall into the redd. Subsequently, the female covers the newly deposited zygotes , again with thrusts of her tail, against the gravel at the top of the redd. The female lays from 1,000 to 2,000 eggs in several clutches within

[REDACTED] Media related to Tana River (Fennoscandia) at Wikimedia Commons Humpback salmon Pink salmon or humpback salmon ( Oncorhynchus gorbuscha ) is a species of euryhaline ray-finned fish in the family Salmonidae . It is the type species of the genus Oncorhynchus ( Pacific salmon ), and

174-692: Is a 361-kilometre (224 mi) long river in the Sápmi area of northern Fennoscandia . The river flows through Finnmark county, Norway and the Lapland region of Finland . The Sámi name means "Great River". The main tributaries of Tana are Anarjohka and Karasjohka . The Tana Valley is the core area for "the River-Sami Culture" in Finnmark; salmon fishing is central in regard to that culture. History: According to written sources since

203-536: Is held by a salmon caught on the Tana; it was 36 kilograms (79 lb) and was taken in 1929 by the Nils Mathis Walle. In 2023, Norwegian authorities constructed a barrier with a trap that has sorted out hundreds of humpback salmon (on some days), while allowing other fish to pass. The installation is in the vicinity of Seidaholmen - and downstream of it. In August that year, media said that disassembly of

232-513: Is the fifth longest in Norway. The last 105 kilometres (65 mi) of the river run through the municipality of Tana in Norway. The river discharges into the Tanafjorden , one of the largest and most unspoiled river deltas in Europe. The delta is protected and is an important home to wetland birds. There are large deposits of sand in the delta that are exposed sandbars at low tide. During

261-539: Is the smallest and most abundant of the seven officially recognized species of salmon . The species' scientific name is based on the Russian common name for this species gorbúša (горбуша), which literally means humpie . In the ocean, pink salmon are bright silver fish. After returning to their spawning streams, their coloring changes to pale grey on the back with yellowish-white belly (although some turn an overall dull green color). As with all salmon, in addition to

290-843: The Arctic to as far south as tributaries of Puget Sound , Washington , although they were also reported in the San Lorenzo River near Santa Cruz, California in 1915, and the Sacramento River in northern California in the 1950s. In 2013, a new record for the southernmost extent of spawning pink salmon was published for the Salinas River . In the fall of 2017, a dozen pink salmon were counted in Lagunitas Creek about 25 miles (40 km) north of San Francisco, California . Pink salmon were introduced into

319-808: The Great Lakes of North America, where there are now self-sustaining populations, and in Iran . In Europe, pink salmon have been periodically introduced to rivers of the White Sea and Barents Sea basins in Russia since 1956. Stray fish from these rivers have been encountered ascending to rivers also in Norway, Sweden, Ireland, Great Britain, and Iceland; and, in Norway, even self-sustaining populations have been observed. In 2017, larger numbers than usual of this species were caught in rivers in Scotland and spawning

348-429: The dorsal fin , they also have an adipose fin. The fish is characterized by a white mouth with black gums, no teeth on the tongue, large oval-shaped black spots on the back, a v-shaped tail, and an anal fin with 13–17 soft rays. During their spawning migration , males develop a pronounced humped back, hence their nickname "humpies". Pink salmon average 4.8 pounds (2.2 kg) in weight. The maximum recorded size

377-482: The 1980s. More than 20 million harvested pink salmon are produced by fishery-enhancement hatcheries, particularly in the northern Gulf of Alaska. Pink salmon are not grown in significant numbers in fish farms. The fish are often canned, smoked or salted. Pink salmon roe is also harvested for caviar , a particularly valuable product in Asia. There is some evidence the pink salmon fishery industry may be having an impact on

406-469: The authorities permit fishing, one can purchase a fishing permit (for angling ). Some residents, can get a permit for fishing with barrier net ; ['salmon-letter owner' or] laksebreveier use net for fishing. New fishing rules, are being considered (as of March 2023) by the parliament of Finland. The Tana is well known for its excellent salmon fishery and is the most productive salmon river in Finland and Norway. The world's record for Atlantic salmon

435-512: The barrier had started. The Tana Bridge (or Nybrua) was constructed in 2020, replacing the function of a neighboring bridge from 1948; its main span is 234 metres (768 ft). The Sami Bridge at Utsjoki was constructed in 1993. The European route E6 highway follows the western shoreline of the river for most of the length of the river. In winter, there are usually two ice roads that are in use from December to April. These roads are located near Rustefjelbma and near Polmak and have

464-471: The last half of the 16th century , fishing has been a major livelihood for the Sami people in the river valley . Another source says since the 17th century . Environmental concerns: erosion at the mouth of the river, in addition to extreme weather , is making the mouth of the river wider but more shallow (as of the 2020s); there is a risk that salmon [or more salmon] during low tide will turn away (from

493-445: The late 19th century fish traps were used to supply fish for commercial canning and salting . The industry expanded steadily until 1920. During the 1940s and 1950s, pink salmon populations declined drastically. Fish traps were prohibited in Alaska in 1959. Now, most pink salmon are taken with purse seines , drift nets or gillnets . Populations and harvests increased rapidly after the mid-1970s and have been at record high numbers since

522-548: The redd, often fertilized by different males. Females guard their redds until death, which comes within days of spawning. In dense populations, a major source of mortality for embryos is a superposition of redds by later-spawning fish. The eggs hatch from December to February, depending on water temperature, and the juveniles emerge from the gravel during March and April and quickly migrate downstream to estuaries, at about one-quarter gram in weight. The fish achieve sexual maturity in their second year of life. They return to freshwater in

551-601: The river) during approach to the river for spawning, according to a committee leader in Tana's municipal council. The ocean has a (considerable) effect on the river, for c. 10 km from the mouth of the river. In its upper course, it runs for 256 km (159 mi) along the Finnish–Norwegian border , between Utsjoki Municipality (in Finland) and Karasjok Municipality and Tana Municipality (in Norway). The river

580-739: The salmon are eggs or fry, through large fish, seabirds, and marine mammals when they are in the ocean. Eggs and the carcasses of spawned salmon adults can provide substantial nutrient subsidies to freshwater food webs. Where pink salmon are expanding into subarctic Norwegian rivers, their eggs are consumed by native salmonids. In the Keogh River in Canada, higher numbers of pink salmon eggs were shown to reduce competition among other fish species relying on this food source. Bears feed on adult migrating salmon, and choose to prey on salmon which have not yet spawned and thus are more nutritious, when they have

638-426: The state of Washington , pink salmon runs occur on odd years. Adult pink salmon enter spawning streams from the ocean, usually returning to the stream where they originated. Spawning occurs between late June and mid-October, in coastal streams and some longer rivers, and in the intertidal zone or at the mouth of streams if hyporheic freshwater is available. Using her tail, the female digs a trough-shaped nest, called

667-597: The streams. NatureServe lists the pink salmon as critically imperiled in California, and imperiled in Washington. In Alaska and British Columbia , they are considered secure. No pink salmon Evolutionary Significant Units are listed under the Endangered Species Act . The commercial harvest of pink salmon is a mainstay of fisheries of both the eastern and western North Pacific. In 2010,

696-575: The summer of 2024, salmon fishing will be banned, as ordered by Finnish authorities and Norwegian authorities; however, fishing for species other than salmon will be facilitated; There will be some opportunities for fishing humpback salmon ; The summer season (for fishing) started in May. In July 2024, media said that on Finland's side of the river, applications were made to allow for young people to learn salmon fishing; however, individuals are not allowed to apply - applications must be made by an association or

725-413: The summer or autumn as two-year-old adults. In their freshwater stage, juvenile pink salmon consume invertebrates and zooplankton. In the ocean, they feed on a variety of plankton, invertebrates, and small fish. Adults do not feed as they return to freshwater to spawn. Many different animals feed on pink salmon throughout their life cycle, from small fish, birds, and mammals in freshwater ecosystems when

754-497: The total harvest was some 260 million fish, corresponding to 400,000 tonnes. Of this, 140 million fish were from Russian fisheries and 107 million from the USA (Alaska). Pink salmon account for 69% of the total Russian salmon fisheries. The majority of pink salmon are harvested using coastal set net traps , and the fisheries are concentrated on the east coast of Sakhalin (average 110,000 tonnes per year). In North America, beginning in

783-804: Was 30 inches (76 cm) and 15 pounds (6.8 kg). The native range of the species is in the Pacific and Arctic coastal waters and rivers, from the Sacramento River in northern California to the Mackenzie River in Canada ; and in the west from the Lena River in Siberia to Korea and Honshu in Japan . In North America , pink salmon spawn from the Mackenzie River in

812-437: Was recorded. In 2021, they were reported to have invaded Akerselva in downtown Oslo , the capital of Norway . Pink salmon are coldwater fish with a preferred temperature range of 5.6 to 14.6 °C, an optimal temperature of 10.1 °C, and an upper incipient lethal temperature of 25.8 °C. Pink salmon in their native range have a strict two year life cycle, thus odd and even-year populations do not interbreed. In

841-399: Was the annual total of salmon captured in the river. Previously, in 2002, fishermen on the river captured an annual total of 99,546 kilograms (219,461 lb) salmon, with an average size of 4.5 kilograms (9.9 lb). The annual sea trout catch for that year on the river was 4,426 kilograms (9,758 lb). Both Finland and Norway regulate the fishing on the river. During the years when
