Особенности формирования зимних скоплений шпрота в восточной части Балтийского моря под влиянием океанологических факторов.
The regularities in the formation of winter sprat stocks in transitional period (the end of autumn - the beginning of winter) depending on oceanological factors are revealed. It is established that its behaviour and distribution patterns are caused by the peculiarities in cooling down the upper layer of the sea. Winter area of sprat is determined by temperature and oxygen conditions in deep-water layer of the sea. In the years of increased oxygen content in deep-water layer the expansion of its winter area occurs, and in the years of decreased oxygen content the narrowing of the area is observed.
