In the Vologda region, work continues on the artificial reproduction of the valuable fish population. So, in Lake Onega, at the mouth of the Andoma River, 1696 white fish weighing about 10 grams each were released. Before settlement, the condition of the fish was checked by experts of Rosrybolstvo and the regional branch of the All-Russian Research Institute of Fishery and Oceanography. The level of water temperature and oxygen were also evaluated. All this in order for the seg to have a good root.
