О возможности прогнозирования запасов зоопланктона в Балтийском море и Рижском заливе
The statistical relationship between crustacean plankton stocks and environmental factors in the Baltic Sea and the Riga Bay during different seasons from 1960 to 1984 is investigated. Regression analysis is used to ascertain the influence of different environmental factors on zooplankton productivity. The authors show that the quantitative development of the zooplankton in spring (May) is governed by the temperature and the severity of the winter, whereas in summer it is governed by food availability and in autumn mainly by auto-correlative relationships (open sea) and the combination of food availability and temperature (in the bay). Regression equations are presented for forecasting the number and biomass of zooplankton for 3, 6, 9 and 12 months in advance and for the possible deviations of the actual values from those calculated.
