bacteria is decreased in this process, which may result in a renewed 

 increase in production of the entire community. We found this at 

 155°W. Apparently, the net production of the community undergoes 

 significant, regular fluctuations against a background of overall 

 reduction. Probably, changes in the production of the community occur 

 analogously as it develops in other regions of the ocean. 



Thus, the materials accumulated to date give us some idea of the 

 production of populations of marine planktonic animals, of trophic 

 levels of zooplankton and of the planktonic community as a whole. 

 However, as we have noted, due to the paucity of factual material, it is 

 difficult to draw any broad conclusions concerning the intensity of 

 production of planktonic animals and zooplankton in general in waters of 

 different trophicities and in different geographic zones of the World 

 Ocean. However, we can hope that the problem of efficient utilization 

 of the resources of the World Ocean which has now arisen will lead in 

 the next few years to rapid development of studies of the process of 

 production in marine communities, allowing us to develop descriptions of 

 these processes for the entire World Ocean and for its individul parts, 

 thus approaching a solution of the problem of prediction and even 

 control of the productivity of marine ecosystems.
