In this connection optimal correlation between the environment temperature and food availability that determines the rates of physiological processes and the amount of energy expenditure are of paramount importance for power-consuming physiological processes, and generative in particular. In accordance with temporal variability in the temperatures of the environment and productivities of the deep water and surface layers of the sea, changes in biological state and distribution of sprat by the sea areas in separate seasons are observed.

Authors: Грауман, Г. Б.; Кренкель, К. Abstract: The first cooperative ichthyoplankton survey was carried out on board the research vessels of IfH and BaltNIIRH throughout the sprat spawning area from the 'Bay of Mecklenburg to the Gulf of Finland. Reproduction conditions and regularities in sprat distribution at early stages of ontogenesis were investigated within a vast sea area. The tendency towards an increase in sprat abundance at early stages of development was established. The most intensive sprat spawning was noted in Bornholm area: 73 % of the total amount of eggs was spawned here in May. By the amount of eggs within the spawning area, absolute size of sprat spawning populations for Subdivisions 22, 24, 25, 26, 28, 29, 32 was determined in May, and for Subdivisions 25, 26, 28, 29 in June, and constituted 24,346 • 106 and 32,746 • 106 individuals, respectively.
