Figure 6. — The relationship between average standing stocks 

 of prey (grams ash-free dry weight of polychaetes per square 

 meter) and predator (grams wet weight of Dover sole per 10 m^) 

 at the seven stations. 



stocks of predator and prey have been elucidated 

 by Brocksen et al. ( 1970) for the biomass of phyto- 

 plankton and zooplankton and for zooplankton 

 and sockeye salmon among ecosystems with dif- 

 ferent productivities. This is the first example, to 

 our knowledge, of such a relationship for the 

 marine benthos.
