This article is devoted to development of actions for improvement of quality of the electric power in rural areas and also in the areas remote from settlements, by installation of booster transformers (BT), and to calculation of economic effect in comparison with alternative versions of the solution of tasks of ensuring reliable, high-quality and available power supply of consumers.

Northeast arctic cod stock is one of a most valuable target of fisheries in the Barents Sea. The catches of cod for the period 1960-2014 are widely changed. The minimum level of catches is marked in 1990 (212 thousands ton), and the maximum values of catches were observed in 1969 – 1.2 mill. ton. In the recent years international catch of cod exceeded 1 mill. ton. Fishable and spawning stock biomass (SSB) also widely changed in this period. According to ICES data, SSB had a minimum in 1965 (102 thousand tons), and extremely high level in 2013 – 2 150 thousand tons. Fishable biomass changed also widely. The maximum level is registered in 2013 – 3 636 thousand tons, and minimum value was 5 times less, 739 thousand tons (1983). The ratio between historical high level of SSB and catch in 2013 was 2.2:1.0, due to low value of fishing mortality. Possibility to increase catch will be discussed.
