Summary[edit]
| Description |
English: фото — большая, или байкальская, голомянка (Comephorus baicalensis). Вместе с малой голомянкой, или голомянкой Дибовского (Comephorus dybowski), она входит в род голомянок. У больших голомянок самки достигают длины 23 см, самцы — 15 см, у малых — 15,8 и 12 см. Голомянки — эндемики озера Байкал. Оба вида лишены чешуи и плавательного пузыря, однако проблему плавучести каждый вид решает по-своему (см. ниже). Голомянки составляют большую часть биомассы Байкала и служат пищей байкальским нерпам (Pusa sibirica)
Ab: photo - large, or Baikal, golomyanka (Comephorus baicalensis). Together with the small golomyanka, or Dibovsky's golomyanka (Comephorus dybowski), it is included in the golomyanka genus. In large golomyankas, females reach a length of 23 cm, males - 15 cm, in small golomyankas - 15.8 and 12 cm. Golomyankas are endemic to Lake Baikal. Both species lack scales and a swim bladder, but each species solves the problem of buoyancy in its own way (see below). Golomyankas make up the majority of Baikal's biomass and serve as food for Baikal seals (Pusa sibirica)
English: Golomyanka (Comephorus), the only genus of fish of the golomyanka family, the perch-like order. The body is naked, pale pink; pelvic fins absent, pectoral fins very long. 2 types; live only in Lake Baikal. G. large (C. baicalensis) (body length up to 19 cm) is more fat, usually kept in the water column, deeper than 800 m is not found. G. small (C. dybowskii) (length up to 15 cm) keeps mainly at a depth of 250-500 m, and at night - at 50-100 m and near the surface; sometimes descends to a depth of 1 km. Both types of G. are viviparous fish; they are characterized by an extremely small number of males (in G. large - only 3% of the total number of fish, in G. small - 12-20%). The females of both species are larger than the males. They have no commercial value. |
