Salvelinus alpinus erythrinus, also known as Baikal charr or davatchan, is a subspecies of freshwater fish in the salmon family. It is endemic to the mountains north of Lake Baikal in the Russian Far East. The fish is edible and it is reported that the population of the species shrunk rapidly over the recent years due to over-fishing. [1]

Description

The Baikal charr is benthopelagic, residing at or near the bottom of the lake. [2] The fish can grow to a recorded maximum length of 70 cm (27.5 inches) and up to 4 kg (8.8 lbs).The fish usually feed on microscopic plankton. [3]

The Baikal charr usually have a dark brown body, with yellow spots on both sides of the body. [4]

Salmonidae is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes, consisting of 11 extant genera and over 200 species collectively known as "salmonids" or "salmonoids". The family includes salmon, trout, char, graylings, freshwater whitefishes, taimens and lenoks, all coldwater mid-level predatory fish that inhabit the subarctic and cool temperate waters of the Northern Hemisphere. The Atlantic salmon, whose Latin name became that of its genus Salmo, is also the eponym of the family and order names.

The Dolly Varden trout is a species of salmonid ray-finned fish native to cold-water tributaries of the Pacific Ocean in Asia and North America. Despite the name "trout", it belongs to the genus Salvelinus (chars), which includes 51 recognized species, the most prominent being the brook, lake and bull trout as well as the Arctic char. Although many populations are semi-anadromous, riverine and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the Salvelinus alpinus complex, as many populations of bull trout, Dolly Varden trout and Arctic char overlap.

Salvelinus curilus is a species of anadromous fish in the salmon family. It inhabits the waters of Russian Far East in the Kurile Islands, Sakhalin, Primorye and also Korea and Japan. It has mostly been considered a subspecies of the Dolly Varden trout Salvelinus malma, with the name Salvelinus malma krascheninnikova, and referred to as the southern Dolly Varden or Asian southern form Dolly Varden trout.

Salvelinus is a genus of salmonid fish often called char or charr; some species are called "trout". Salvelinus is a member of the subfamily Salmoninae within the family Salmonidae. The genus has a northern circumpolar distribution, and most of its members are typically cold-water fish that primarily inhabit fresh waters. Many species also migrate to the sea.

Solanum acaule is a species of wild potato in the family Solanaceae, native to Peru, Bolivia, northern Chile, and northwestern Argentina. The complete chloroplast genome of S. acaule was constructed by de novo assembly using Illumina paired-end (PE) sequencing data. The chloroplast genome of S. acaule is circular and has a length of 155,570 bp and typical quadripartite consisting of 86,020 bp of large single copy, 18,364 bp of small single copy, and 25,593 bp of a pair of inverted repeat regions. A total of 158 genes were annotated including 105 protein-coding genes, 45 tRNA genes, and eight rRNA genes. Maximum likelihood phylogenetic analysis of the sequence with 31 species in the Solanaceae revealed that S. acaule is fully resolved in a large clade with nine other Solanum species including S. tuberosum. It is being extensively studied for its resistance to Phytophthora infestans, Potato leafroll virus, Potato virus X, Potato virus Y, potato cyst nematodes, and frost, in an effort to improve the domestic potato Solanum tuberosum.
