D. Encrusting Bryozoa 



Site 1 encrusting bryozoan data for 1956-58 did not change 

 significantly from those presented by Maloney (1958) for 1956-57. 

 Monthly encrusting bryozoa set and growth repeated the bimodal peaks 

 which were altered only by an expansion of the June-July peak to 

 include identical set intensity during July-August and a slight set 

 increase in September-October (Fig 27). 



Figure 29 shows very little change in the percent of panel coverage 

 pattern. The Site 1 September-October peak set shown in Figure 27 

 replenished the stock and probably caused the growth increase in the 

 October-November-December cumulative panels after a September- 

 October decay as shown in Figure 30. It should be pointed out that 

 these organisms conform to accepted ideas of productivity potential 

 per unit area. Figure 31 demonstrates this relationship vividly in the
