THE SEA OF AZOV 489

 (A. Novoshilova, 1958) 



This was observed also in the autumn, when the 'marine' plankton moved 

 eastwards. In subsequent years the Sea of Azov zooplankton biomass decreased 

 owing to the change in the flow of the river Don {Table 201). 



General quantitative characteristics of zooplankton and its seasonal 

 changes are given in Figs 232 and 233.

and Novoshilova).
