PS Insufficient sample size -1,0 D. pulicaria length (mm) FIGURE 8. Species composition by numbers of Cladocera present in the Big Bear Lake plankton and in Big Bear Lake gamefish stomachs, and size-frequency distribution of D. pulicaria in the lake and in fish stomachs during September-November, 1978 (AV = available in environment, RT = rainbow trout, BC = bluegill, PSD = pumpkinseed; upper fig- ure: Black = Chydorus, Cross hatched = D. pulicaria, White = Ceriodaphnia). Copepoda Diaptomus franciscanus was the dominant limnetic copepod in Big Bear Lake, particularly in spring at Stations III and VIII (Figure 9). D. franciscanus has a prolonged reproductive period in Big Bear Lake, producing several generations per year. Population peaks occurred in spring and late summer-early fall. D. franciscanus nauplii were present throughout the study (Figures 9 and 10). D. franciscanus overwinters primarily in late copepodid stages which mature and reproduce in early spring, producing the first generation (Figure 10). Hatching.
