Table 16. Calculation of annual production P and P^ of a population of 

 Buccinum cyaneum var. tenebrosum from the eastern portion of the Barents 

 Sea by a static-dynamic method based on one-time analysis of the status 

 of the population in early fall. 



NOTE: ^Iq NW is the biomass of population B; AWs is the weight gain 

 of an individual of a given size during the current year (up to the 

 moment of observation); for individuals born that year, it is equal to 

 their weight, for individuals which were older, it is equal to the 

 difference between their weight and the weight of individuals one year 

 younger, calculated from the weight growth curve; NaWs is the production 

 of individuals present (not eliminated) of the given size in the year, 

 adding up to the supporting production of the population P^ for the year 

 up to the moment of observation; AWg is the expected annual weight 

 increase of individuals of a given size; for all individuals except 

 those having the maximum size in the population, it is calculated from 

 the curve of weight growth as the difference between the weight of 

 individuals of a given size and the individuals a year older; NAWg is 

 the production of individuals present and eliminated of a given size 

 over the course of the year, while in some it represents the growth 

 production of the population P over the year in question up to the 

 moment of observation. ^
