The number of salmonid taxa within some genera (e.g. Salmo, Salvelinus, and Coregonus) listed in various taxonomic databases (e.g. Fishbase or Eschmeyer's Catalog of Fishes) has increased very rapidly over the past 15-20 years. Many of these taxa are not widely accepted across the international community and are associated with very sparse data, leading to significant difficulty in accurately carrying out Red List assessments. The SSG strongly recommends a rigorous evaluation of the validity of these species designations, which can have real implications where legal protection is reflected by the use of these binomial taxonomic names.

Salvelinus taranetzi is a widespread species recorded from the eastern Arctic to the Bering Strait and down to the northern Sea of Okhotsk, Russia. This species is commercially fished but not in all areas of its range, and the overall impact of fishing is not considered to be high. It occurs within multiple protected areas. Therefore, it is assessed as Least Concern.

Salvelinus taranetzi is a widespread charr species, recorded from the eastern Arctic to the Bering Strait and down to the northern Sea of Okhotsk, Russia. This species is widespread in the sub-Arctic Pacific from Chukotka to Dezhnev Bay. Due to the presence of migratory fish, the population system forms a continuous range and reaches a high abundance. The lakes of the territory are inhabited by residential forms. In the southern part of the range, the distribution is patchy, with only relict populations inhabiting only deep lakes of glacial origin.

Searching for populations is recommended in the peripheral part of the Ichigemsky ridge, 40 km south of Lake Verkhnepenzhinsky in the basins of the Kholokhovchan and Shayboveyem rivers (the Karovoye - Lednikovoye, Romany - Svetloye and Gornoye systems of lakes). Reliable findings in the Penzhina will close the gap in the area of distribution between the northern coast of the Sea of ​​Okhotsk and Kamchatka.

This species is abundant and common across its range (Chereshnev 2002, 2008). Chereshnev (2008) indicated a period (1970-1980s) when the species was dramatically overharvested. However, for its current occurrence within Chukotka, Chereshnev (2008) indicates that the state of the population is unknown due to almost complete cessation of scientific and fishery research in inland waters. It is assumed that the population is increasing as in recent decades economic activity and the population of chukotka Autonomous Okrug has significantly decreased.

Semi-anadromous populations live in basins that connect to large lagoons (Lake Achchen) or in the lagoon lakes themselves (Lake Pekulneyskoe, Mainitz). Typical lake populations occur in mountain lakes remote from the coast (Nuteneut, Gytgylveeyrgytgyn, Pychgynmygytgyn). In Koryakia and Kolyma, a high ecological diversity is recorded. Isolates can be represented by two forms with different growth rates (Darpir Lake, Cherechen). In some cases, the growth rate, lifestyle, and morphology change in adulthood (ontogenetic groups from Lake Ayaogytgyn). On the southern border of the range, the populations are monomorphic, can be represented by a form with fast growth (lakes Nachikinskoye, Dvuyurtochnoe, Podsopochnoe) or with slow growth (lakes B. Sokoch, Sapozhok).

The age limit of this species is 22 years, with a length of 96 cm, and weight of 13.7 kg (Chereshnev 2002, 2008). Most of the populations are anadromous, but there are also known land-locked residential forms inhabiting the same river systems together with the anadromous populations (Chereshnev 2002, 2008). Not all fish migrate to the sea every year, sometimes staying in fresh water for several years (Chereshnev 2002, 2008). The largest numbers are found in river drainages, which include deep large lakes, where the species reproduces and winters (e.g., rivers Ioniveem, Koolen’veem and Seutakan) (Chereshnev 2002, 2008). Marine migrations seem to be limited to coastal zones. Adults in the sea eat zooplankton and fish; during the period of mass run of young salmon (Pink Salmon, Sockeye Salmon) they switch to its consumption (Chereshnev 2002, 2008). The young of this species feed on zooplankton when in lakes, and on small benthos when in rivers (Chereshnev 2002, 2008). From the sea, fish start to enter rivers in early July with the mass run in August-September. The spawning season is very long, with the majority of individuals spawning in late summer to early autumn, and the rest in late autumn to winter, and even the following spring, but not every year (Chereshnev 2002, 2008). Spawning usually occurs in lakes at a depth of 4-5 m. It most probably builds redds on gravel and sandy ground and buries its eggs (Chereshnev 2002, 2008). This species spawns for the first time at the age of 4-8 years, at 12-21 cm length and 56-96 g weight; males earlier than females (Chereshnev 2002, 2008). Fecundity is 0.51-8.7 (more often 0.86-4.5) thousand eggs. Eggs are yellow and 3-5 mm in diameter.

This species is an object of local commercial fisheries (Chereshnev 2002). This species is, however, widespread in areas that are not impacted by fishing.

This species is an object of local commercial fisheries (Chereshnev 2002).

Further research to clarify the population dynamics is recommended. It is recommended to survey for this species in the peripheral part of the Ichigemsky ridge, 40 km south of Lake Verkhnepenzhinsky in the basins of the Kholokhovchan and Shayboveyem rivers (the Karovoye - Lednikovoye, Romany - Svetloye and Gornoye systems of lakes). Reliable findings in the Penzhina will close the gap in the area of distribution between the northern coast of the Sea of ​​Okhotsk and Kamchatka. This species range is greatly widespread and so it occurs within the boundaries of multiple protected areas, such as Koryak State Natural Reserve and State Natural Complex Reserve "Swan".
