Dolly Varden and Arctic char have been confused by anglers and biologists in Alaska. The Dolly Varden is one of the most widely distributed salmonids in Alaska. It occurs throughout the coastal areas of the state from southeast Alaska across the Gulf of Alaska and the Bering Sea into the Beaufort Sea to the Mackenzie River in northern Canada.
The Dolly Varden trout is a species of salmonid native to cold-water tributaries of the Pacific Ocean in Asia and North America. It is in the genus Salvelinus of true chars, which includes 51 recognized species, the most prominent being the brook, lake and bull trout, as well as Arctic char. Although many populations are semi-anadromous, fluvial and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the Salvelinus alpinus or Arctic char
Most seasoned guides guess somewhere around infinity, maybe a little more. The Alaska Fish and Game Biologist specializing in Dolly and Char thinks there may be both Dolly Varden and Arctic Char in the river. On goes the debate, but we all know what they are. Arctic char and Dolly Varden had similar numbers of alleles (17.8 vs 17.3) when pooled across all sites. Dolly Varden showed the highest number of alleles for a single locus (39 at locus OtsG83b followed by 38 at locus Sco200). 2020-09-24 · Dolly Varden are mainly semi-anadromous, meaning they will spend part of their time in the sea but primarily live in freshwater rivers or lakes. Arctic Char The last of the char species in North America are aptly named the Arctic Char.
They stage early season in the tidal flats and then eagerly follow the surge of salmon up the rivers and streams, strategically positioning themselves below the spawning salmon.Come mid-September, they display absolutely stunning spawning colors. The Arctic char or Arctic charr (Salvelinus alpinus) is a cold-water fish in the family Salmonidae, native to alpine lakes and arctic and subarctic coastal waters. Its distribution is Circumpolar North. It spawns in fresh water and populations can be lacustrine, riverine, or anadromous, where they return from the ocean to their fresh water birth rivers to spawn.
of Dolly Varden and Arctic char in western Alaskan lake sys-tems showed that sympatric forms were reproductively isolated from one another and acted as valid species (Taylor et al. 2008). Consequently, historical introgression may be responsible for the relationship between Dolly Varden and Arctic char mtDNA

The identical to the IW2-2015 female characteristics of diagnostic loci were found in other individuals from the broodstock TR. The sea-run Dolly Varden populations in this remote region of the Alaska Peninsula are very healthy. Catch rates can verge on ridiculous. They stage early season in the tidal flats and then eagerly follow the surge of salmon up the rivers and streams, strategically positioning themselves below the s Analysis of the absolute values of genetic disctances of the S. alpinus--S. malma forms relative to S. leucomaenis, S. fontinalis, and S. namaycush revealed distances approaching the species rank between the following isolates: Frolikh Char, Mountain Char, Black Lake Char, Goggle-Eyed Char, and Neyva Char. Samples of Dolly Varden currently considered as "S. malma", do not constitute a separate Call for prices and gear information. In Northwest Alaska the best time to target Dolly Varden in during the spawn which runs from the first week of August through week 3.
Alaskan Dolly Varden and Arctic Char Meet The Fish: Dolly Varden and Arctic Char Named for Charles Dickens eponymous character with a predilection for brightly spotted dresses, the Dolly Varden char is indeed a flamboyant dresser especially during spawning season. Whether Dolly Varden, Arctic char, or lake trout, these subspecies are all part of the genus called char. We all know, however, that they are different fish.

Anadromous Arctic chars spend their juvenile years in fresh water, and once mature, migrate annually to the marine environment. Arctic Alaska Dolly Varden Morphologically, each lake system contained two forms: one (Arctic char) largely confined to lake habitats and characterized by greater numbers of pyloric caeca, gill rakers, and shallower bodies, and another (Dolly Varden) predominated in adjacent stream habitats and was characterized by fewer pyloric caeca, gill rakers, and deeper bodies. between Arctic char and Dolly Varden throughout this zone of sympatry (e.g., pyloric ceca, gill raker counts), McPhail (1961) identified populations that had ambiguous (A) (B) Figure 1. Char can be targeted at the season opener all the way to ice over in many rivers and streams.
